I20 GARRETT: CATALOGUE OF CYPR^IDiE, 



52. C. (Aricia) tessellata, Sowb. This, like C. su/a'dentata, 

 is ouite rare, and is found only at the Sandwich Islands. 

 We obtained beach specimens on the west coast of Hawaii 

 and on the north coast of Kauai. It is generally recorded from 

 New Zealand, but I very much doubt its occurrence there. 



53. C. (Luponia) tigris, L. This common and well-known 

 cowry occurs in more or less abundance inside the reefs at 

 all the groups. 



They are very variable in size and color. The largest 

 examples, which were obtained at Cook's Islands, measured 

 5 inches in length, whilst the smallest, found at the Carolines, 

 is only 2| inches in length. 



The animal has a creamy-yellow mantle, closely veined 

 longitudinally with deep brown, and marked with a few 

 diffuse spots of the same color. It is also furnished with 

 small, stout, tentacular processes of an amber-yellow color, 

 tipped with white; the processes are either cylindrical or 

 slightly compressed, and simple or bifid. Head, tentacles 

 and siphon grey. The upper surface of the foot is marbled 

 with black, deep brown, and fawn-yellow ; creeping disk 

 purple-brown with darker veins. 



54. C. unifasciata, Mighels. Rather rare; under dead coral 

 on the outer reefs. Obtained only at the Sandwich and 

 Society Islands. The late Mr. Pease considered it a variety 

 of C. fimbriata. The two species are certainly very closely 

 allied, and the color of the animals are quite similar. 



Having now before me about a dozen perfect specimens 

 of each species, I note the following differences: — Mighels' 

 species is larger, the teeth coarser, less numerous, and the 

 ground color, which is of a more bluish tint, is marked with 

 a more or less broken, transverse, yellowish-brown band. 

 Both species have the terminal pink spots as well as the 

 profusion of small yellow dots.
