40 THE NAUTILUS, 



Cypraea 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 cruenta, 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 \\, breadth i 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 brilliancy 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. MelvilP, 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 

 mixed than were these poor little waifs.
