Genus Cyprcea. 227 



slightly flattened at the base, extremities less produced than 

 in the type, but more so than in C. tiirdiis, aperture fairl}- 

 wide, two last anterior labial teeth distinct and projecting, 

 as in Lantarckii and iniliaris. Dorsal surface pale-ochreous, 

 indistinctly marked with obscure whitish spots, laterally 

 thickened with white callosity on each side, and a double 

 row of brown spots (almost becoming blotches in one 

 specimen), which impart a special character at first sight. 

 Size about the same as the type. 



I take this shell to be very well developed and full 

 grown Lamarckii. I had at one time, some eighteen years 

 ago, when I gave the MSS. name of redimita to the speci- 

 mens then acquired at a dealer's in Liverpool, imagined the 

 species was a new one. I have found an example among 

 the Cholmondeley shells now at Owens College, rather larger 

 than my own, but not so well marked as that now 

 photographed. 



The underside is the same as C. turdus, and were it not 

 for the projecting ridges of the two last labial teeth, which 

 are never found in that shell, I should have been inclined 

 to connect the two species more closely. 



C. iniliaris (Gmel.); {a) magistra (var. nov.), (fig. 6). \ 

 very large variety, lately acquired through Mr.G.B.Sowerby, 

 from Japan. Character the same as in the type, but teeth 

 very well developed and size, long. 2^, lat. i^ inch. I 

 have seen five or six other specimens in no other way 

 differing. It is a handsome shell, and in fine condition ; 

 it slightly resembles C. guttata on dorsal surface only. I 

 consider C. ebnrnea (Barnes), often reckoned a mere albino 

 form of this, a sufficiently good species. 



C. iniliaris (Gmel), C. Lamarckii (Gray), and C. Listeri 

 (Gray) are commented upon by the Rev. R. Boog Watson, 

 B.A., F.L.S., in his " Report on the Gasteropoda, Voyage of 

 H.M.S. Challenger," Vol. XV., pp. 424, 425. To quote his 

 remarks : 'Tn classing the Challenger specimen (of C. iniliaris,
