A conclusion not unworthy of observation may be deduced from this

catalogue; namely, that Ceylon was the unknown, and hence

unacknowledged, source of almost every extra-European shell which has

been described by Linnæus without a recorded habitat. This fact gives to

Ceylon specimens an importance which can only be appreciated by

collectors and the students of Mollusca.

2. RADIATA.

The eastern seas are profusely stocked with radiated animals, but it is

to be regretted that they have as yet received but little attention from

English naturalists. Recently, however, Dr. Kelaart has devoted himself

to the investigation of some of the Singhalese species, and has

published his discoveries in the Journal of the Ceylon Branch of the

Asiatic Society for 1856-8. Our information respecting the radiata on

the confines of the island is, therefore, very scanty; with the

exception of the genera[1] examined by him. Hence the notice of this

extensive class of animals must be limited to indicating a few of those

which exhibit striking peculiarities, or which admit of the most common

observation.

[Footnote 1: Actinia, 9 sp.; Anthea, 4 sp.; Actinodendron, 3 sp.;

Dioscosoma, 1 sp.; Peechea, 1 sp.; Zoanthura, 1 sp.]

_Star Fish_.--Very large species of _Ophiuridæ_ are to be met with at

Trincomalie, crawling busily about, and insinuating their long

serpentine arms into the irregularities and perforations in the rocks.

To these they attach themselves with such a firm grasp, especially when

they perceive that they have attracted attention, that it is almost

impossible to procure unmutilated specimens without previously depriving

them of life, or at least modifying their muscular tenacity. The upper

surface is of a dark purple colour, and coarsely spined; the arms of the

largest specimens are more than a foot in length, and very fragile.

The star fishes, with immovable rays[1], are by no means rare; many

kinds are brought up in the nets, or maybe extracted from the stomachs

of the larger market fish. One very large species[2], figured by

Joinville in the manuscript volume in the library at the India House, is

not uncommon; it has thick arms, from which and the disc numerous large

fleshy cirrhi of a bright crimson colour project downwards, giving the

creature a remarkable aspect. No description of it, so far as I am

aware, has appeared in any systematic work on zoology.

[Footnote 1: _Asterias_, Linn.]

[Footnote 2: _Pentaceros?_]

_Sea Slugs_.--There are a few species of _Holothuria_, of which the

trepang is the best known example. It is largely collected in the Gulf

of Manaar, and dried in the sun to prepare it for export to China. A

good description and figures of its varieties are still desiderata.

_Parasitic Worms_.--Of these entozoa, the _Filaria medinensis_, or

Guinea-worm, which burrows in the cellular tissue under the skin, is

well known in the north of the island, but rarely found in the damper

districts of the south and west. In Ceylon, as elsewhere, the natives

attribute its occurrence to drinking the waters of particular wells; but

this belief is inconsistent with the fact that its lodgment in the human

body is almost always effected just above the ankle. This shows that the

minute parasites are transferred to the skin of the leg from the moist

vegetation bordering the footpaths leading to wells. At this period the

creatures are very small, and the process of insinuation is painless and

imperceptible. It is only when they attain to considerable size, a foot

or more in length, that the operation of extracting them is resorted to,

when exercise may have given rise to inconvenience and inflammation.

These pests in all probability received their popular name of

_Guinea-worms_, from the narrative of Bruno or Braun, a citizen and

surgeon of Basle, who about the year 1611 made several voyages to that

part of the African coast, and on his return published, amongst other

things, an account of the local diseases.[1] But Linschoten, the Dutch

navigator, had previously observed the same worms at Ormus in 1584, and

they are thus described, together with the method of removing them, in

the English version of his voyage.

"There is in Ormus a sickenesse or common plague of wormes, which growe

in their legges, it is thought that they proceede of the water that they

drink. These wormes are like, unto lute strings, and about two or three

fadomes longe, which they must plucke out and winde them aboute a straw

or a feather, everie day some part thereof, so longe as they feele them

creepe; and when they hold still, letting it rest in that sort till the

next daye, they bind it fast and annoynt the hole, and the swelling from

whence it commeth foorth, with fresh butter, and so in ten or twelve

dayes, they winde them out without any let, in the meanetime they must

sit still with their legges, for if it should breake, they should not,

without great paine get it out of their legge, as I have seen some men

doe." [1]

[Footnote 1: JOHN HUIGHEN VAN LINSCHOTEN _his Discours of Voyages into

the Easte and West Indies._ London, 1599, p, 16.]

The worm is of a whitish colour, sometimes inclining to brown. Its

thickness is from a half to two-thirds of a line, and its length has

sometimes reached to ten or twelve feet. Small specimens have been found

beneath the tunica conjunctiva of the eye; and one species of the same

genus of _Nematoidea_ infests the cavity of the eye itself.[1]

[Footnote 1: OWEN'S _Lectures on the Invertebrata_, p. 96.]

_Planaria_.--In the journal already mentioned, Dr. Kelaart has given

descriptions of fifteen species of planaria, and four of a new genus,

instituted by him for the reception of those differing from the normal

kinds by some peculiarities which they exhibit in common. At Point

Pedro, Mr. Edgar Layard met with one on the bark of trees, after heavy

rain, which would appear to belong to the subgenus _geoplana_.[1]

[Footnote 1: "A curious species, which is of a light brown above, white

underneath; very broad and thin, and has a peculiarly shaped tail,

half-moon-shaped in fact, like a grocer's cheese knife."]

_Acalephæ_.--Acalephæ[1] are plentiful, so much so, indeed, that they

occasionally tempt the larger cetacea into the Gulf of Manaar. In the

calmer months of the year, when the sea is glassy, and for hours

together undisturbed by a ripple, the minute descriptions are rendered

perceptible by their beautiful prismatic tinting. So great is their

transparency that they are only to be distinguished from the water by

the return to the eye of the reflected light that glances from their

delicate and polished surfaces. Less frequently they are traced by the

faint hues of their tiny peduncles, arms, or tentaculæ; and it has been

well observed that they often give the seas in which they abound the

appearance of being crowded with flakes of half-melted snow. The larger

kinds, when undisturbed in their native haunts, attain to considerable

size. A faintly blue medusa, nearly a foot across, may be seen in the

Gulf of Manaar, where, no doubt, others of still larger growth are to be

found.

[Illustration: PHYSALUS URTICULUS.]

Occasionally after storms, the beach at Colombo is strewn with the thin

transparent globes of the "Portuguese Man of War," _Physalus urticulus_,

which are piled upon the lines left by the waves, like globules of glass

delicately tinted with purple and blue. They sting, as their trivial

name indicates, like a nettle when incautiously touched.

_Red infusoria_.--On both sides of the island (but most frequently on

the west), during the south-west monsoon, a broad expanse of the sea

assumes a red tinge, considerably brighter than brick-dust; and this is

confined to a space so distinct that a line seems to separate it from

the green water which flows on either side. Observing at Colombo that

the whole area so tinged changed its position without parting with any

portion of its colouring, I had some of the water brought on shore, and,

on examination with the microscope, found it to be filled with

_infusoria_, probably similar to those which have been noticed near the

shores of South America, and whose abundance has imparted a name to the

"Vermilion Sea" off the coast of California.[1]

[Footnote 1: The late Dr. BUIST, of Bombay, in commenting on this

statement, writes to the _Athenæum_ that: "The red colour with which the

sea is tinged, round the shores of Ceylon, during a part of the S.W.

monsoon is due to the _Proto-coccus nivalis_, or the Himatta-coccus,

which presents different colours at different periods of the

year--giving us the seas of milk as well as those of blood. The coloured

water at times is to be seen all along the coast north to Kurrachee, and

far out, and of a much more intense tint in the Arabian Sea. The

frequency of its appearance in the Red Sea has conferred on it its

name."]

The remaining orders, including the corals, madrepores, and other

polypi, have yet to find a naturalist to undertake their investigation,

but in all probability the new species are not very numerous.

NOTE.

TRITONIA ARBORESCENS.

The following is the letter of Dr. Grant, referred to at page 385:--

Sir,--I have perused, with much interest, your remarkable communication

received yesterday, respecting the musical sounds which you heard

proceeding from under water, on the east coast of Ceylon. I cannot

parallel the phenomenon you witnessed at Batticaloa, as produced by

marine animals, with anything with which my past experience has made me

acquainted in marine zoology. Excepting the faint clink of the _Tritonia

arborescens_, repeated only once every minute or two, and apparently

produced by the mouth armed with two dense horny laminæ, I am not aware

of any sounds produced in the sea by branchiated invertebrata. It is to

be regretted that in the memorandum you have not mentioned your

observations on the living specimens brought you by the sailors as the

animals which produced the sounds. Your authentication of the hitherto

unknown fact, would probably lead to the discovery of the same

phenomenon in other common accessible paludinæ, and other allied

branchiated animals, and to the solution of a problem, which is still to

me a mystery, even regarding the _tritonia_.

My two living _tritonia_, contained in a large clear colourless glass

cylinder, filled with pure sea water, and placed on the central table of

the Wernerian Natural History Society of Edinburgh, around which many

members were sitting, continued to clink audibly within the distance of

twelve feet during the whole meeting. These small animals were

individually not half the size of the last joint of my little finger.

What effect the mellow sounds of millions of these, covering the shallow

bottom of a tranquil estuary, in the silence of night, might produce, I

can scarcely conjecture.

In the absence of your authentication, and of all geological explanation

of the continuous sounds, and of all source of fallacy from the hum and

buzz of living creatures in the air or on the land, or swimming on the

waters, I must say that I should be inclined to seek for the source of

sounds so audible as those you describe rather among the pulmonated

vertebrata, which swarm in the depths of these seas--as fishes, serpents

(of which my friend Dr. Cantor has described about twelve species he

found in the Bay of Bengal), turtles, palmated birds, pinnipedous and

cetaceous mammalia, &c.

The publication of your memorandum in its present form, though not quite

satisfactory, will, I think, be eminently calculated to excite useful

inquiry into a neglected and curious part of the economy of nature.

I remain, Sir,

Yours most respectfully,

ROBERT E. GRANT.

_Sir J. Emerson Tennent, &c. &c._
