BUCCINUM. 243 
Bucci vate. 
The Cassis rufa of authors (Kiener, Coq. Viv. Cas. pl. 7, 
f. 12, 13) is marked for this species in the Linnean cabinet. 
The synonymy being very nearly correct (Seba, pl. 78, f. 2, can 
alone be excepted), the shell, being described at large in the 
‘Museum Ulrice,’ was recognised with facility by naturalists at 
an early period. 
Becetwim tuberosum. 
The Buccinum tuberosum, as it appears in the twelfth edition 
of the ‘Systema,’ is a recognisable species, thanks to the ad- 
mirable engraving of Gualtier, which is there referred to as 
illustrative. As the shell there delineated is decidedly the 
Cassis tuberosa of authors (so too is one of the two figures in 
Labat’s ‘ Voyage’), of which the characters are not in opposition 
to the very brief diagnosis, we may regard the species as pic- 
torially defined. I should not venture, however, to cite, as 
identical, the Linnean #Buccinum thus ‘named in the tenth 
edition (where Gualtier, though habitualiy consulted by Lin- 
nus, was not referred to, and where his figure was queried for 
a variety of echinophorum), nor that of the ‘Museum Ulrice,’ 
where the account of its aperture does not coincide with the 
characteristics of that part in the Cassis tuberosa; neither of 
these two, however, even if different, can be identified; hence 
the acceptance of the subsequent definition. The addition of 
“ Apex suturis membranaceis” in the revised copy favours the 
received opinion. 
The shell, being too large for the drawers of the Linnean 
cabinet, is not retained with the rest of the specimens, but a 
marked example (Seba, Mus. vol. in. pl. 73, f. 2) is still pre- 
served in the Linnean Society's Museum, apart from the other 
specimens. Unfortunately, however, a large example of Cas. 
labiata (List. Hist. Conch. pl. 1108), a species usually confused 
with cornuta, has been inscribed with the same numerals.
