pleistocenp: fossils 245 



Gylichna occulta. Mighels and Adams. 



Fossil — Montreal ; Murray Bay ; Maine. 

 Recent — Greenland to New England. 



Gylichna striata. Brown. 



Fossil — Riviere-du-Loup and Clyde beds. 



Recent — Arctic seas. JeflFreys thinks this the same with the pre- 

 ceding species. 



Haminea soUtaria. Say. 



Fossil — Montreal ; rather common. 



Recent — New England and northward. 



If this species is rightly determined, it furnishes a curious instance 

 of a somewhat southern species occurring in the drift of Montreal. 

 The Hamineoi, however, can scarcely be identified by weathered or 

 fossil specimens, so that this may possibly be a northern form distinct 

 from solitaria. 



Diaphana dehilis. Gould. 



Fossil — Montreal. 



Recent— Gulf St. Lawrence (VVhiteaves) ; Greenland to New 

 England. 



Jeffreys considers it the same with B. hyalina, Turton. If so, it 

 is a shell of the Clyde beds and of the Arctic seas generally. 



Utriculus pertenuis. Mighels. 



Fossil — Montreal. 



Recent— Labrador (Whiteaves) ; Gulf St. Lawrence, and south to 

 Cape Cod. According to Jeffreys it is U. turritus, Moller, Greenland.
