Determinations of Mollusca. 

 By Mr. C. Hedley, F.L.S., Conchologist. 



"After spending considerable time on Mr. Mawson's collec- 

 tion, I return it with such identifications of shells as I was able 

 to make. It contains a number of species which are probably 

 new to science, but the task of elaborating these for publication 

 would be both lengthy and laborious. Viewed as recent species, 

 the material is not well enough preserved for description. The 

 collection represents material from a deeper zone than the beach. 

 As no dredging has been done in this archipelago, nothing is 

 known of the deep-water fauna, with which this collection ought 

 to be compared. The lot numbered 165 [Tasiriki foundation- 

 beds] reminds me of the mollusca I dredged in 15 fathoms off 

 the Palm Islands. In lot 242 [Foreland fossiliferous cinder-beds] 

 the appearance of Cucullcea, Conus, Pleurotoma, and Cardium 

 suggests a like origin."
