244 SPECIES OF THE SYSTEMA. 
Bucci flanuvetunr. 
‘T'wo very distinct Cassides, the C.flammea of authors, and the 
C. crumena (now generally regarded as a variety of testiculus), 
were indicated by the respective references to Rumphius and 
Bonanni, and from the extreme brevity of description affected 
. inthe ‘Systema’ would about equally suit the definition. As 
the rude drawing of Bonanni, however, was quoted also for 
B. plicatum in the tenth edition, it may be presumed not to 
have been very characteristic of either: it has been rejected in 
the ‘Museum Ulrice,’ where, indeed, the “ articulata suturis” 
would have been wholly inapplicable to the shell represented 
by it. Hence naturalists, from the account in that publica- 
tion being in harmony with the only engraving there cited as 
illustrative, have selected the Cassis delineated by Rumphius 
(C. fammea, Sowerby, Genera Shells, Cas. f. 2) as the repre- 
sentative of the Linnean species. It seems somewhat strange, 
however, that Linneus (who has not recorded his own posses- 
sion of an example) should not have referred also to Seba, 
vol. ii. pl. 73, f. 10, 11, 14, 15, 19, 20; most of those figures, 
however, exhibit the shell in its maturity, in which stage it does 
not appear, from the remark “ Distinguendum a B. rufo, quod 
nodi nulli in dorso, aisi circa collum,” to have been known to 
him, at least by this appellation.

The Cassis testiculus of authors (Crouch, Introd. Lam. Conch. 
pl. 18, f. 7, a) is marked for this species in the Linnean cabinet. 
In the ‘Museum Ulrice’ the synonyms are accurate, and the 
description characteristic ; but the “ levigata” in the ‘ Systema,’ 
though clearly meant, from the context, to denote merely the 
absence of knobs and folds, might readily mislead one; so too 
might the description of the pillar lip. Plate 73, f. 19, 20 of 
Seba’s ‘Museum’ represent the preceding shell; the references 
are otherwise correct. In quoting that work our author has
