Testa subrotunda, inflata, lævis. Apertura oblonga, non utrinque
dentata. Spira obsoleta. Columella obliqua.
The _Murex ficus_ and _rapa_ of the printed edition were originally
located in this genus, from which _Auris Midæ_, _Auris Judæ_, and
_achatina_ were excluded: the two former were placed in _Morion_, the
last in _Buccinum_.
B. OVUM. _B._ birostris, labio dentato.
"Arg. t. 21. f. A." "Pet. Gaz. t. 94. f. 7." "Pet. Amb. t. 8. f. 6."
were additional references in the written copy: "magnitudine ovi
gallinacei", "apice et basi producta", were emendations during the
printing. The "dilatata" was originally modified by a "parum."
B. VOLVA. _B._ birostris, rostris elongatis striatis.
"List. t. 711. f. 63" had been added to the copy by the hand of Linnæus.
The mode of reference (not, as in the earlier writings, by sections and
chapters) evinces that this addition was, in all probability, subsequent
to the publication of the work.
B. VERRUCOSA. _B._ angulata, aucta utrinque puncto osseo.
The correct synonyms of "Arg. t. 21. f. M." and "Pet. Gaz. t. 97. f.22."
were found in the manuscript: the printed emendations were, "magnitudine
ovi passerini", "uti anterius", and "granis duobus" for the earlier
"punctis."
B. GIBBOSA. _B._ angulata, cingulo elevato.
"Bonan. 249", "List. t. 711. f. 64", "Pet. Gaz. t. 15. f. 5", were
cited in the copy: "præcedentis magnitudine", "solidiorque", with
the modification of "cylindrica" by a preceding "sub", were press
emendations.
B. NAUCUM. _B._ rotundata pellucida.
The size was not at first mentioned.
B. AMPULLA. _B._ rotundata opaca.
The printed "nulla" replaced the earlier "descendens, nuda", and
"pallido-testacea" the written "albida." The "antice, nullus vero
postice" was an emendation of the press.
B. PHYSIS. _B._ spira obtusa, lineis crispata.
"Sæpe", "hiansque", "tenue", and the name, are not to be found in
the written copy: "apicem" was the reading for the printed "ventrem,
aduatum."
B. AMPLUSTRE. _B._ spira elevata, fasciis incarnatis.
B. PALLIDA. _B._ spira elevata acuta, corpore cylindrico.
So very many changes has this puzzling species experienced in the
works of our author, that it has been thought advisable to transcribe
the written description from the manuscript copy:--
Testa ovato-cylindrica, glabra. Spira convexo-conica, mucronata.
Columella multum torta. Color lividus, longitudinaliter grisco
undulatus.
This evidently was a very different shell from the four-plaited, pale
pink, and often variegated specimen described in the printed copy.
The description of the outer lip, the name, and the terms "solida",
"lævigata, obsoletior" were, likewise, additions of the press.
B. CANALICULATA. _B._ cylindrica lævis, spiræ anfractibus
canaliculatis.
The entire account of this species was added to the manuscript in the
Linnean handwriting.
B. ACHATINA. _Buc._ glabrum, apertura integra.
"Colum. Aphr. 18. t. 16" was the omitted synonym: "vel inæqualiter
ovata" and the entire account of the base (merely described as "vix
manifeste emarginata") were the printed additions.
B. AURIS-MIDÆ. _Morion_ ovali-oblongum, spira rugosa, labio interiore
bidentato.
Figure 122 of Klein's seventh plate was correctly quoted as
illustrative: "crudæ" preceded "niger."
B. AURIS-JUDÆ. _Morion_ oblongus, spira lævi, labio interiore
tridentato.
B. SOLIDULA. _B._ ovata opaca striata, spira elevata.
I do not doubt, from the "ovata", that _Tornatella flammea_ was the
shell originally here intended; for the inharmonious account of
the inner lip (as well as of the outer one) was not found in the
manuscript,--from which, too, the erroneous reference to Bonanni was
at first absent. The "acutiuscula" was "obtusiuscula": the "postice
rotundata, antice acuta" was an improvement upon the earlier "pone
gibba."
B. LIVIDA. _B._ spira elevata obtusa, corpore cylindrico.
This heading makes no mention of the columellar plication of the
shell so named in the 'Systema,' and confirms my surmise of their
distinctiveness. The name _livida_ was not originally attached to the
description, but had been added (together with "obsoletis") by Linnæus,
from a mistaken identification.
There has evidently been some error in the comparison with _Voluta
Caffra_. I suspect that _Conus bullatus_ was meant, as the contrasting
characters answer admirably. "Differt a _B. pallida_ et _livida_, quod
testa solida--anfractus spiræ canaliculati". This passage shows that
"fragilis et spiræ anfractus obtusæ" referred to _livida_, not to
_Caffra_.
