200 EOCENE MOLLUSCA. 
Lamarck, and, since his time, MM. Deshayes and D’Orbigny, have considered 
C. lineatus as identical with C. stromboides (Lamk.), from the Paris basin. These two shells 
do not appear to me, however, to be referable to the same species, for in the French 
species the shell is narrower, the spire more elevated, and formed of more numerous 
volutions ; the whorls, also, are more rounded at the shoulders, the transverse lineation 
is feebler and more irregular, and the outer lip is more strongly arched than in the 
English shells. I have, therefore, not cited C. stromboides as a synonym of the presen 
species. 
So closely does C. lineatus resemble C. scabriculus, from which, in fact, it is only 
distinguished by its smooth, crowded, concentric lines, separated by rounded furrows, 
that it ought, perhaps, to be regarded as merely a variety into which the smooth lined 
specimens of the latter species would lead ; but, without an examination of Brander’s 
shell, I do not venture to question Solander’s species. 
Size-—The dimensions of my largest specimen are—axis, 7-12ths of an inch; 
diameter, rather more than 3-12ths of an inch : those of Brander’s shell were, according 
to the figure—axis, 10-12ths of an inch ; diameter, rather more than 5-12ths of an inch. 
Localities.— Barton, Bracklesham Bay. Very rare.

Shell rather thick, fusiform, resembling two nearly equal cones, placed base to base, 
and ornamented with concentric raised lines; the spire, forming the shorter cone, is 
elevated, pointed, and terminates in a very small conical pullus of three volutions; whorls
