Hah. North-east end of Malajta Island, Solomon group. 



The specimens from the above locality are very closely 

 allied to the type of Helix Behnoret, Cox*, from Iloki 

 Island, also one of the Solomon group. They differ in 

 being more depressed and consequently more sharply angled 

 at the periphery, and they have not the " irregular longi- 

 tudinal stria3 " (which might be more explicitly described as 

 irregular impressed spiral lines) upon the base. The type 

 of H. Belmorei was presented to the British Museum by 

 Dr. Cox, and from an examination of it I am inclined to 

 think that these impressed lines are rather an individual 

 characteristic than a specific feature. I therefore think it 

 advisable to consider the specimen sent by Mr. Brazier as a 

 variety of this species until we have a larger series of the 

 typical form to prove them distinct. H. merziana has a more 

 convex upper surface, is smaller, and the last whorl expands 

 at the aperture.

Hab. Ferguson Island, D'Entrecasteaux group, south-east 

 of British New Guinea. 



The species here described was exhibited by Mr. Brazier at 

 the Linnean Society of New South Wales as representing a 

 new genus, and he proposed to name it Braziera typica. After 

 due consideration 1 have failed to find good reasons for sepa- 

 rating it from Megalomastoma. In shape it is very like 

 M. Gundlachi, Pfeifier. It has, however, a more contracted 

 umbilicus, and the peristome is differently connected with the 

 body- whorl. The fact of this species being from New Guinea, 

 whereas Megalomastoma mainly comprises West-Indian forms,
