40 THE NAUTILUS. 
Cyprza Greegori Ford, n. sp. 
Shell depressed, orbicular oval in form, callus on the sides and 
ends remarkably thickened. That on the sides light salmon in color, 
with irregular purple-brown spots, having a blotchy appearance. 
Dorsal surface similar to that of erwenta, but lacking the whitish 
spots typically present in that species. Base semi-translucent, spot- 
less, dark buff or salmon colored, darkest in the interstices. Teeth 
on outer lip very strong, long and whitish ; on inner lip finer, with 
exception of the anterior fold and one or two adjacent teeth, the first 
of these latter being very prominent and notably transverse. Space 
between the anterior fold and the following tooth wide and bright- 
ened ; posterior teeth of inner lip prolonged outward upon the base. 
Dimensions of average specimen: length 14, breadth ¢ inch. 
That C. Greegori is more nearly related to C. cruenta than to any 
other species, I have no doubt. But it is equally true that the 
former possesses several characters altogether distinct from those 
belonging to the latter. For instance, C. greegori is more translu- 
cent, more rugged, much smaller and rounder in form, different in 
general color, and in the peculiar variations of the teeth, also in the 
remarkable thickness and brillianey of the callus with which it is 
rimmed. 
With the probable exception of one poor specimen, this shell was 
unknown to the late Mr. Tryon, and for the same reason, perhaps, 
it was not noticed in Mr. Robert’s catalogue of the species. Never- 
theless, an excellent figure of it was published by Kiener' who merely 
referred to it as a variety of C. cruenta (variolaria). A figure, 
possibly intended for the same shell, was also published by Sowerby’ 
who seems to have considered it a variety of C. caurica. More 
recently, Sowerby’s figures were alluded to by Mr. J. C. Melvill’, as 
the var. coloba, but whether this variety was referable to C. cruenta 
or C. caurica, seems to have been a question that he was either unable 
or unwilling to decide. At least, in one sentence he apparently 
makes C. cruenta responsible for its parentage, while in another 
sentence the same honor is given to C. caurica. Verily it seems that 
even the babes in “ Pinafore” could not have been more hopelessly 
rixed than were these poor little waifs.
