GARRETT: CATALOGUE OF CYPRiEID^. 119 



It is, by some authors, supposed to be a mere variety of 

 Trivia staphyloea. Judging from the few specimens before 

 me, I do not hesitate to pronounce it a distinct species. It 

 is perfectly smooth, of a tawny-brown color, profusely dotted 

 with white. The teeth, about 20 on the outer lip, are pale 

 yellowish-white, and margined with hair-like, buff-yellow lines. 

 The canal at either extremity is also buff-yellow. The teeth 

 on the middle portion of the columellar lip are very short, 

 leaving a large smooth space on that portion of thc'shell. 



Trivia staphyloea is studded with raised white dots, and 

 the teeth extend quite across the face of the shell. 



47. C. (Aricia) sulcidentata, Gray. This rare species seems 

 to be confined to the Sandwich Islands, where we found 

 beach specimens. 



48. C. tabescens, Sol. This rather scarce cowry was found at 

 all the Eastern Polynesian groups. We obtained living ex- 

 amples on the outer reefs, lurking under stones and concealed 

 among sea-weeds. 



Animal vermilion-red, with a pale creeping disk. Siphon 

 dotted with whitish and fringed at the end. The mantle is 

 ornamented with dark red spots, white dots, and studded 

 with dendritic processes. 



49. C. talpa, L. Common at the Paumotus, but more or less 

 rare at the other groups. It inhabits deep water outside the 

 reefs. 



50. C. testudinaria, L. This fine large species, which is 

 rarely found, lives in deep water outside the reefs. They 

 occur at all the islands in Western Polynesia, and range east 

 as far as the Society Islands. The animal of this and the 

 preceding species are unknown to me. 



51. C. teres, Gmel. Also a rare species, and obtained only at 

 the Paumotu and Society Islands, where they were found 

 washed up on the sands.
