GARRETT : CATALOGUE OF CYPRiEIDiE. 121 



55. C. ursellus, Gmel. Somewhat rare, and inhabits all the 

 groups in Western Polynesia. Station, under dead coral on 

 the inner margins of the outer reefs. 



56. C. (Aricia) ventriculus, Lam. Obtained a few examples 

 at all the groups excejit the Marquesas. Young shells show 

 four transverse, reddish-brown bands on a livid ground. 



57. C. (Luponia) vitellus, L. Found in more or less abun- 

 dance in all parts of Polynesia, and are usually obtained 

 inside the reefs. The young are marked with four bands, 

 which become nearly or quite obsolete in the adult shell. 



58. C. (Luponia) sp. This small species was obtained in a 

 dead but perfect condition on the outer beaches at the 

 Kingsmill Islands. We also received it from Swain's Island. 



It is shaped like C. Gaskoinii. The ground color is 

 slightly darker than in that species, the base less white, the 

 teeth, about 20, are larger and have their external portions 

 dark brown. Sides with similar colored spots. Dorsal region 

 sprinkled with different sized white dots, some of which have 

 deep brown centres. Dorsal line nearly obsolete. 



Length 10 mill. 



59. Cypraeovula Adamsonii, Gray. Rather common under 

 clumps of dead coral on the outer reefs at the Society Islands. 

 More rare and smaller at the Paumotus. In the former group 

 they occurred only in a single location on the east coast ot 

 Huahine. 



All the examples have four irregular-shaped, yellowish- 

 brown dorsal spots, and a similar colored row along the 

 right side. 



The animal is yellowish grey, frecked with rich saffron- 

 yellow. The elongate foot is thin, gradually tapering pos- 

 teriorly to an acutely rounded tip, and slightly auriculate in 

 front. The short siphon is without the terminal fringe.
