GARRETT: CATALOGUE OF CYPRMIDM. 1 25 



white beneath, and the ends with a sUght brownish-yellow 

 tinge. The dorsal region is profusely maculated with small, 

 not conspicuous white spots of different sizes. It is more 

 like Luponia than Trivia. 



70. T. (Pustularia) Madagascarensis, Gmel. Not uncom- 

 mon at the Sandwich Islands, where we found a number of 

 specimens washed up from deep water. 



We have two fine examples now before us, one from 

 Starbuck, the other from CaroUne Island, both small islands 

 situated between the Society Group and the Equator. It 

 has never to my knowledge been found in any other part of 

 Polynesia. The name Madagascarensis is no doubt a mis- 

 nomer; its occurrence on the coasts of that island has never 

 been confirmed. 



The two above-mentioned specimens are not so much 

 depressed, and are less dilated than Sandwich Island exam- 

 ples; excepting color they very closely resemble T. nucleus. 

 They are of a pale tawny-flesh color, with the dorsal riblets 

 and tubercles beautifully margined and ringed with violet 

 lines, and the basal ridges with the usual fawn-yellow linea- 

 tions. 



No doubt a large series of specimens of both species 

 will prove that they gradually merge into each other the same 

 as globulus and ciceicula, and limacina and staphylcza. 



71. T. (Pustularia) nucleus, L. Excepting the Marquesas, 



we found this species not uncommon under dead coral on 

 the outer reefs at all the groups. 



As stated in the remark in the preceding species it is 

 very closely allied to T. Madagasca^-ensis. It never attains so 

 large a size, is more convex, narrower, the dorsal ribs and 

 granules more crowded, though similarly ornamented with 

 delicate, fawn-yellow lines.
