A considerable series of specimens from various localities and a 

 careful examination of the literature quoted, enable me to con- 

 fidently unite Montrouzier's species with that of Hinds. It should 

 be obvious to any student who compares the excellent figure in 

 the Journal de Conchyliologie with the other illustrations that 

 the immaturity of the New Caledonian example is the only point 

 of difference. That this synonomy of so common and distinct a 

 species should have so long escaped attention is another sad proof 

 of the negligence of the authors who have dealt with this much 

 abused genus. Reviewing the shells of Lifu, Melvill and Standen 

 actually record the species first under one name and then under 

 the other.* Tryon has suggested T. bayani, Jousseaume, as a 

 probable synonym, an idea which his figures seem to contradict. 

 One of the specimens before me shows the protoconch to have a 

 double keel, with a very narrow interstice. 



The shallow water of the Funafuti lagoon yielded me several 

 broken specimens. A wide range over the Pacific is indicated 

 by the following records : New Guinea (Belcher) ; Queensland, 

 Torres Straits, (Brazier)f and Cape Sidmouth, (Henn); Gilbert 

 Islands (Garrett) ; New Caledonia, He Art (Montrouzier) ; 

 Oubatche and Noumea (Hedley) ; and Lifu (Hadfield). 



TRIFORIS, spp. 



Several other species of Triforis, too worn for identification or 

 determination are included in the collection. 



OVULA HERVIERI, Sp. nOV. 



(Fig 34). 



Shell small, broadly ovate. Colour pale 

 yellow with four spiral bands of rose, visible 

 alike within the aperture, across the callus 

 and on the dorsal surface, these bands are in 

 breadth equal to their interstices. Sculpture 

 about thirty-five flat-topped spiral lyrse, sepa- 

 rated by narrow, sharply incised grooves, 

 surround the shell. The outer lip is much 

 thickened and reflected without, and bears 

 within about ten slight and widely parted
