Dolph._ p. 3.

Odontoceti _or_ Delphinoidea, _Flower_, _l. c._ p. 111.

Teeth well developed in one or both jaws, sometimes deciduous. Palate

without baleen. Head large or moderate, compressed. Tympanic bones two,

dissimilar, separate, becoming united, sunk in a cavity in the base of

the skull. Gullet large.

The suborders in this section have certain relations to each other by

which they may be arranged in two parallel series:—

| A. Nostrils | B. Nostrils

| separate, | united,

| elongated. | transverse.

| |

Teeth only in the lower jaw. Cervical | |

vertebræ often united | Physeteroidea. | Ziphioidea.

Teeth well developed in both jaws. | |

Jaws beaked | Susuoidea. | Delphinoidea.

Division I. _Nostrils longitudinal, parallel or diverging; each covered

with a valve_ (cf. p. 62).

Suborder III. PHYSETEROIDEA.

Physeteroidea, _Gray_, _l. c._ p. 195; _Synops. Whales &

with a valve, the right often obliterated. Teeth many in the lower

jaw, fitting into holes in the gums of the upper one. Lachrymal bone

none distinct. “Costal cartilages not ossified. The hinder ribs losing

their tubercular and retaining their capitular articulation with the

vertebræ. The greater number of the cervical vertebræ ankylosed together.

Pterygoid bones thick, produced backwards, meeting in the middle line,

and not involuted to form the outer wall of the postpalatine air-sinus.

Symphysis of mandible of moderate or excessive length. No functional

teeth in the upper jaw. Mandibular teeth various, often much reduced in

number. Lachrymal bones usually large and distinct. Bones of the skull

raised so as to form an elevated prominence or crest behind the anterior

nares. Orbit of small or moderate size. Pectoral limbs small. Dorsal fin

usually present.”—_Flower._

linear, in front of the upper part of the head. Mouth inferior, linear.

Pectoral fin short, broad, truncate. Dorsal hump rounded. Skull elongate.

Crown concave, surrounded by a high perpendicular wall formed by the

doubled-up maxilla and occipital bones. Upper jaw toothless. Atlas free;

rest of cervical vertebræ united by their bodies and spines into a

consolidated mass.

1. CATODON.

Catodon, _Gray_, _l. c._ pp. 196, 386, 387; Synops. Whales &

Dolph. p. 3.

Physeter, _Flower_, _Trans. Zool. Soc._ vol. vi. p. 309.

The atlas vertebra transverse, nearly twice as broad as high; the central

canal subtrigonal, narrow below. Skull nearly one-third the entire

length of the body. Lachrymal bone wanting. The zygomatic process is

formed of the malar bone. Vertebral column rough and rather spongy.

Vertebræ 50: 7 cervical, 11 dorsal, 8 lumbar, 24 caudal. The atlas

separate; the other 6 cervical united by their bodies and spines into one

consolidated mass, and sometimes united to the first dorsal vertebra.

The atlas subquadrangular, broader than long. The transverse process

truncated. Upper edge nearly straight, lower slightly curved. Neural

canal triangular, one of the angles directed downwards. The thyro-hyal

triangular, thick in front, thinner behind; the basihyal broad and flat.

The basihyal and thyro-hyal united. The ribs long, all but the first

slender and light. The first rib is short, broad, and very thick near

the lower end. Sternum large, triangular, the apex turned backwards. The

broad front end nearly straight, composed of two large anterior and a

small posterior piece. Pectoral limb small. Scapula higher than broad;

outer surface concave, inner convex. Acromion very large, dilated at the

end. Coracoid large, narrow, and about half the length of the acromion.

often united at the ends and separate in the middle. The carpus wide

and short. The carpal bones six, nearly in a single row. The fingers

five, all well developed, the second, third, and fourth not differing

greatly in length, the fourth the shortest; the first consisting of two,

the second and third of six, the fourth of five, and the fifth of four

joints; the second finger two-thirds the length of the arm-bones.

The skull of the young animal is much shorter and broader than in the

adult (Flower, Trans. Zool. Soc. vol. vi. tab. 57).

1. Catodon macrocephalus.

Physeter macrocephalus, _Flower_, _Trans. Zool. Soc._ vol. vi.

p. 309, tab. 55 to 61, and woodcuts.

Inhab. Tropical seas, accidentally in the temperate ones.

Mr. Flower (Trans. Zool. Soc. vol. vi.) considers _C. australis_, Gray,

_l. c._ p. 206, fig. 55, the same species; and certainly there does not

appear to be any character in the skeleton to divide them.

Maury remarks:—“The Sperm-Whale, according to the result of this chart,

appears never to double the Cape of Good Hope. It doubles Cape Horn.

Since this fish delights in warm water, shall we not expect to find off

Cape Horn an under-current of warm water heavier with its salt?”—_Maury_,

_Whale-Charts_, p. 267.

How far the species indicated range beyond the habitats whence they were

received is yet to be discovered and recorded. No doubt their range is

influenced by many local circumstances (peculiarities in the currents,

and disposition of the food) that are not easily observed or understood.

2. MEGANEURON.

Meganeuron, _Gray_, _l. c._ pp. 386, 387; _Synops. Whales &

Dolph._ p. 4.

The atlas vertebra subcircular, rather broader than high. The central

canal subcircular, in the middle of the body, widened above.

The rest of the animal not known; it is placed in _Catodontidæ_ because

this family is the only one that has the atlas separate from the cervical

vertebræ and of the simple form.

the maxillaries, and divided, as it were, into two subequal parts by a

central bony ridge, which is more or less twisted towards the right side.

Physeter, _Gray_, _l. c._ pp. 196, 210, 386; _Synops. Whales &

Dolph._ p. 4.

Head large, rather depressed in front. Skull ⸺?

Only known from Sibbald’s description, which, like his others, is very

specific; and all his other accounts of animals have been proved to be

correct.

Mr. Flower has no faith in Sibbald’s account of this animal, and says,

“If the Linnæan genus _Physeter_ is to be kept in abeyance until the

rediscovery of Sibbald’s ‘_Balæna macrocephala tripinna_,’ it is to

be feared that it may ultimately disappear altogether from zoological

literature.”—_Trans. Zool. Soc._ vol. vi. p. 369.

Inhab. Australia, India. Length 10 feet, young.

The difference between _Kogia_ and _Euphysetes_ does not depend on the

sex of the animals. Mr. Krefft described a male, and Professor Owen a

female specimen; the latter mistook the two drawings of the same specimen

for the two sexes, deceived by certain additions surreptitiously made to

Mr. Elliot’s drawings; but the additions, especially the penis, are not

represented on the plates, and the artist (Mr. Willis) says he received

no directions to leave out any part of the drawing, and accurately copied

them. The measurements given in the paper do not agree with those in Mr.

Elliot’s notes made from the living animal; and reference to them would

have prevented all this confusion.

“The number of the teeth in the different specimens of _Inia_ examined

shows a considerable range of variation, presuming that they all belong

to one species. In the one now described there are R. 26, L. 26 / R.

25, L. 27 = 104. The larger specimen in the British Museum, from Ega,

has 28-28/26-27 = 109, and also two minute rudimentary teeth in the gum

behind the last in the left maxilla. In the smaller skull from the same

place there are 29-26/28-27 = 110. In the skull in the Paris Museum,

brought by D’Orbigny, there are, according to Gervais, 33-33/33-33 =

132; but in the type specimen in the same museum, taken from Lisbon, the

number is given by De Bainville as 26-26/26-26 = 104. In the Berlin skull

the teeth are 34-32/33-32 = 131. Von Martius, in his diagnosis of the

species, gives 28-28/29-29 = 114.”—_Flower._

9. FERESA.

Orca (Feresa), _Gray_, _P. Z. S._ 1870, p. 77.

The beak of the skull from the notch rather shorter than from the notch

to the condyle, depressed, flat above, gradually tapering in front; the

width at the notch two-thirds of the entire length of the beak. Lower jaw

slender, narrow and thin in front, teeth not reaching the notch.

This reexamination has convinced me, and also, I believe, Mr. Flower,

that the skull described under the name of _Orca intermedia_ belongs to

a very small species, and is not “the skull of a very young individual,

probably of one of the large species,” as Mr. Flower supposed, apparently

from the examination of the figure (see Flower, P. Z. S. 1864, p. 425).

Indeed, when the animal is known, I should not be at all astonished if

it should prove to be a species of _Electra_ rather than of _Orca_, or

perhaps a new genus.

This skull has many resemblances to those of some of the species of

_Electra_; the teeth are much smaller than those of _Orca_.

Inhab. ⸺?

This is the skull of a full-grown animal, and yet it is not so large as

the skull of a newly born specimen of _Orca_. Mr. Flower, judging from

the figure, believed it to be the skull of a very young animal; but on

examining the skull along with me he became satisfied, from the solidity

and definite form of the bones, that it is the skull of a full-grown

though not aged specimen.

Inhab. Cape of Good Hope (_Viney_, B.M.; _Villette_, Mus. Coll. Surg. no.

In the Cape specimen the intermaxillaries are nearly of the same width in

the whole of their length; in the Seychelles skull they are contracted in

the greater part of their length, and rather dilated in front.

Mr. Swinburne Ward has kindly sent a very beautiful skull of a “Killer”

taken in the sea near the Seychelle Islands.

To determine this skull I have been induced to compare the skulls of the

genus in the British Museum, which it is very necessary to do from time

to time, as specimens gradually accumulate, and often arrive when I am

occupied on other subjects, and consequently are put aside for future

examination.

In this examination I have observed that in the ‘Catalogue of Seals and

Whales’ I have confounded with the skull described under the name of

_Orca capensis_ one from the North Pacific, the former being the true

_Orca capensis_, and the skull now received from the Seychelles Islands

being of the same species.

The skull figured in the ‘Zoology of the Erebus and Terror’ under the

name of _O. capensis_ is from a specimen received from the Zoological

Society, to which it was presented by Capt. Delville, who said he

obtained it in the North Pacific (?). It is quite a different species,

for which I propose the name of _Orca pacifica_. I doubt its being from

the _North_ Pacific, as I believe there is a skull of the same species

in the Paris Museum, collected by M. Eydoux, and said to have come from

Chili.

Delphinus orca, _Cuv._ _Oss. Foss._ v. tab. 22. fig. 4 (skull).

The skull very similar to that of the Cape species, but much smaller;

but the beak is rather narrower, the intermaxillaries moderately broad,

slightly dilated in front.

Inhab. North Sea.

An adult skull from the coast of Essex (361 _a_), and another without the

lower jaw, are in the British Museum.

These skulls of the smaller British, or, rather, European _Orca_ are

distinguishable from those of _O. gladiator_ by the smaller size and

the broader, rounder nose—and from the skulls of the Cape-of-Good-Hope

species by being of a much smaller species, and having a depressed crown

of the head.

I believe the skull figured under the name of _Delphinus orca_ by Cuvier,

Oss. Foss. vol. v. tab. 22. figs. 3, 4, represents this species, from the

form of the beak and the narrowness of the occiput: this figure has been

copied by various British and other authors.

Inhab. Mediterranean, Cette.

Skull about 22 inches long. It is about the same size as the _Orca_ from

Algoa Bay; but the brain-cavity is rather broader and the beak is not so

acute in front.

Gervais, in the ‘Zoology and Paleontology of France,’ figures the skull

of a young _Delphinus orca_, taken on the coast of Cette, which is now

in the Museum of Paris. It appears to belong to this species; or it

may be that the _Orca_ of the Mediterranean does not grow to the usual

size; or, again, it may be of a different species; for the skull is only

fifty-eight centimetres long and thirty broad.

free; the second with a large dorsal process.

“The Narwhal and the _Beluga_ appear to separate themselves from all

the rest, by certain well-marked structural conditions, especially the

characters of the cervical vertebræ. As these two animals are in almost

every part of their skeleton nearly identical, even to the number of

the vertebræ and phalanges, I am disposed to look upon the exceptional

dentition of the former as an aberration of secondary importance, and to

unite the two genera into a distinct subfamily, placing it next to the

Platanistidæ.”—_Flower_, _l. c._ p. 114.

The animal figured by Gervais as _Delphinus (Stenodelphis) Blainvillii_

(Voy. Amér. Mérid. t. 23) differs from Burmeister’s figure in having an

elongated subfalcate pectoral fin, and a higher dorsal, and a broad white

streak, commencing from the blower and extending down the back to near

the tail. If this is not a figure of the animal seen at sea, which I

suspect it must be, it must be a different species.

“One small tooth imbedded close to the tip of lower jaw on left side, 1

“This is the skull of a young animal. A groove containing a strong

ligament connecting the muscle of the forehead with the snout is deeply

imbedded in the intermaxillary groove. The snout is described as long and

flexible. Atlas and axis anchylosed. Length of cervical vertebræ 3⁷⁄₁₀

inches. Scapula, longitudinal diameter 10 inches, transverse diameter 6

inches. Paddles, length 14 inches, width 3½ inches. Hyoid arch 5½ × 4

inches high. Pelvic bones 2½ inches.

“The specimen was cast on the beach on the west coast, and prepared by

Dr. Knox.”—_Hector._

“Your _Berardius_ proves to be quite different from the first one we got,

both in the dentition and form of the skull. We have had several good

papers on it from Dr. Knox. He has made a beautiful preparation, showing

that the tooth does not pass through the gum.”—_Dr. Hector_, letter dated

30th October, 1870.

“A fine specimen of _Berardius arnuxi_ has been cast ashore on the coast

of Canterbury, New Zealand. It was made into a skeleton, which is now in

the museum at Canterbury. The skeleton is complete, only wanting one of

the pelvic bones. It was 30 feet long, and a young animal; not a single

epiphysis is anchylosed. The cervical vertebræ, which, in the old animal

evidently form a compact mass, are still partly free; the first three

vertebræ (including the atlas) anchylosed, and of these the first two

completely, and of the second and third the neural arches are as yet not

completely united into one bone. It has ten ribs.”—_Julius Haast._

The animal was 30 feet 6 inches long.

Deep velvet-black, belly greyish, tail with two falcate lobes 6½ feet

broad. The pectoral fins are little above the middle of the body, 17

inches broad and 19 inches long, of a triangular form. Dorsal fin small,

falcate, not very far from the chin (?). “The animal has the power of

protruding the four teeth at will.” They live on cephalopods. The stomach

contained about a half-bushel of the horny beaks of the _Octopus_, which

were nearly all the same size. It was evidently a young animal, as all

the disk-like epiphyses of the vertebræ are still separate, as was the

case with the limb-bones.

The seven cervical vertebræ were beginning to coalesce; the first three

are already anchylosed, the first two completely, and the second and

third only partially, as the neural arches and transverse processes are

not yet united in one bone. It has ten dorsal vertebræ; the lumbar and

caudal vertebræ were not observed. (Dr. Haast, Annals & Mag. Nat. Hist.,

Oct. 1870.)

The form of the lower jaw gives a very peculiar appearance to the

skeleton. The cervical vertebræ are united together by their bodies and

large dorsal spines, the latter forming a thick conical process. The

bodies of the dorsal vertebræ are very small, enlarging in size towards

the tail; they are thirty-six in number. The four terminal caudal ones

are very small, forming a kind of cylindrical process. There are eight

chevron bones. The thoracic cavity is small. There are twelve ribs on

each side. The dorsal processes of the first eighteen vertebræ have an

anterior basal process, which becomes gradually smaller.

Upper arm-bone very slender, slightly curved; the lower arm-bones

moderate, straight, parallel to each other, and rather longer than the

upper arm-bone. The ribs very broad at the upper end, and gradually

tapering towards the chest, where they are nearly cylindrical.

“The total length of the skeleton, without cartilage, is 14 feet 8

inches; the head measures 2 feet 5½ inches in length, and the lower

jaw 2 feet 3 inches in length. The first three cervical vertebræ are

anchylosed; the next one is more or less free; and the remaining three

are anchylosed again. The dorsals are ten in number, the last bearing a

short rib 8 inches in length. Five of these ribs are jointed direct to

the sternum; the following two meet the cartilage of the fifth rib.

“The sternum is composed of four pieces, 20 inches long, with a width of

between 5 and 7 inches. It is not yet sufficiently cleaned to enable me

to have it photographed; this, however, will be done as soon as possible,

and copies forwarded to the Society. The lumbars number twenty, the last

nine having V-bones attached. The fifth lumbar is 17½ inches high, 4

inches wide at the top, and 11¾ inches at the base, including the side

processes. The eleventh lumbar is the widest, being 4¾ inches at the top.

The caudals probably amounted to 13; but five of these are missing; the

basal one is very small, about the size of a pea; and as it was firmly

attached to the second last, there can be no mistake about it.

“The head is 2 feet 5½ inches long and 14 inches across at the widest

part; the lower jaw 2 feet 3 inches long and 6¼ inches high behind the

tooth. The left tooth measures 6 inches in length, 3⅜ inches in width,

and is 1¾ inch thick [not well represented in the figure]. The space

between the teeth measures 7¼ inches. The limbs are very imperfect; all

the smaller bones are missing; and there is only a part of one scapula. I

did not find the pelvic bones.

“This animal was captured about a year ago, near Lord Howe’s

Island.”—_Krefft_, P. Z. S. 1870, p. 426.
