2o6 Mr. Cosmo Melvill on the 



eye-like holes are cut out, as it were, by some secreting 

 juices ; leaving them clearly defined, and there is no sign of 

 the blurred lateral striae, so conspicuous in vitellus. C. dania 

 (Ferry), Conch, xxiii., 3, has been supposed to be nk'osa, 

 and thus to claim precedence of title. But I am convinced, 

 on examining Mr. Perry's figure, that vitellus was intended^ 

 for the ' hair-like marks at the sides ' are not only mentioned 

 in this description, but also delineated. Broderip's name 

 will therefore stand. This species is very rare ; found at the 

 Mauritius. My specimen came from Mr. Lombe Taylor's 

 collection. The dentition of both these is identical. 



C. vitellus (L.) (ci) sarcodes (var. nov.). — A colour variety, 

 of pale uniform flesh colour, otherwise as in the t}'pe. 

 Figured. Sowb. Thes. Conch., pi. vi., £31. 



G. cainelopardalis (Perry) was for many years confounded 

 with vitellus, but the absence of lateral striation, the clear- 

 ness of marking, and the smoky black interstices between 

 the columellar teeth distinguish it. Common in the Red 

 Sea. Better known by the later name of ^nelmiostoma 

 (Leathes). 



C. pulcJiella (Swn.). 



C. pyriforviis (Gray). 



Two beautiful and rare shells, allied to each other, and 

 with a connection, too, with G. Walkcri, but otherwise 

 isolated. This latter, however, has a characteristic violet 

 tinge, never found in the two under observation, and through 

 this shell there may be a connection with G. lynx (L.). 



C. pulchella (Swn.) is truly pyriform, whitish, dorsal sur- 

 face pale brown spotted, with or without a central deep 

 brown blotch, sides spotted, base white, shining, teeth 

 extending over the centre of the base, and labial teeth well 

 developed, red. Length i % inch. Chinese Seas. 



C. pyriformis (Gray) and its small variety G. Sniithi 

 (Sowerby). On dorsal surface pale cinereous, mottled with 

 darker. Truly pyriform in shape, teeth on the outer lip
