THE MOLLUSCA HEDLEY. 455 



TRIVIA ORYZA, Lamarck. 

 Tryon, loc. cit., p. 200, pi. xxi., figs. 79, 82, 83 ; Garrett, loc. cit., 



pp. 107, 126. 



Several dead specimens of a small form of this species were 

 collected on the beach of the Funafuti lagoon. 



This ranges along the Australian coast as far south as Sydney. 

 Garrett remarks that this has the same range and station in 

 Polynesia as the preceding species. Rossiter notes it from 

 Noumea, New Caledonia, and the Loyalty. It is shown in 

 this Museum from the New Hebrides. 



DOLIUM PERDIX, Linne. 

 Tryon, loc. cit., p. 264, pi. iii., fig. 15 ; pi. iv., figs. 23 - 25. 



I was unable to obtain an example of this circumsequatorial 

 species on Funafuti, but I identified one purchased from a native 

 by another member of our party. 



Melvill and Standen note this from Lifu. This Museum has 

 representatives from British New Guinea, the Solomons, Erro- 

 manga, New Hebrides, New Caledonia, the Gilberts, and Niue. 



DOLIUM POMUM, Linne. 

 Tryon, loc. cit., p. 265, pi. v., fig. 26. 

 One specimen from the lagoon beach. 



Tryon quotes this from the Society Islands. Material in this 

 Museum indicates it from British New Guinea, New Caledonia, 

 and the Gilberts. 



CASSIS CORNUTA, Linne. 



Tryon, loc. cit., p. 270, pi. i., figs. 45, 46 ; pi. ii., fig. 49. 



I collected no examples of this personally, but at Funafuti I 

 remarked it in use as shell trumpets, and at Nukulailai I purchased 

 specimens. There the natives called it " pou," and told me it 

 was not rare. New Caledonian examples are contained in this 

 Museum. 



CASSIS VIBEX, var. ERINACEA, Linne. 



Tryon, loc. cit., p. 277, pi. vii., fig. 90. 

 Two dead shells from the lagoon beach. 



TRITONIUM TRITONIS, Linne. 

 Tryon, Man. Conch., iii., 1881, p. 9, pi. i., fig. 1 ; pi. iii., fig. 16; 



pi. iv., fig. 25. 



I did not myself collect this species. Mr. J. O'Brien told me 

 that it was sometimes found on the leeward reefs alive. The 

 natives recognised an engraving of it as " bofala."
