TRIFORIS DOLICHA, Watson. 

 Watson, Chall. Report, Zool., xv., 1886, p. 565, pi. xlii., fig. 1. 



One specimen from the Funafuti lagoon agrees exactly with 

 another now before me from Prince of Wales Island, Torres 

 Straits. Young specimens were collected ofl' Cape Sidmouth, 

 Queensland, by Mr. A. U. Henn, and presented to this Museum. 

 The " Challenger " collected it a little west of Cape York. 



The two adult specimens I have seen are pure white, punctuated 

 between the gemmules with orange ; in neither is the lip more 

 developed than in the "Challenger" example. It may be that this 

 species does not attain the spurred lip of its congeners. 



TRIFORIS .SJGLE, Jousseaume. 



(Fig. 27) 



Jousseaume, Bull. Soc. Mai. France, 1884, p. 256, pi. iv., fig. 12 ; 

 Tryon, Man. Conch., ix., 1887, p. 185, pi. xxxix., fig. 40. 



Jousseaume's account, as reflected in Tryon's Manual is too 

 scanty to allow of a proper determination, and with much doubt 

 I assign here a Funafuti species. A single specimen of T. cegle, 

 from Noumea, presented by Mr. R. C. Rossiter, now before 

 me, is too immature to show the aperture. It is a larger and 

 lighter coloured shell than those from Funafuti, and the gemmules 

 seem rather closer together. As, however, it fairly corresponds 

 to the Ellice shells in apex and sculpture, I prefer, instead of 

 adding another name to the long list of Triforis, to assume that 

 the one figured and described below is a variety of Jousseaume's 

 species. The still more scanty information published relative to 

 T. collaris, Hinds, suggests that it should also be compared.
