PLEISTOCENE FOSSILS. 213 



Recent Gulf and River St. Lawrence, 30 to 313 fathoms. G. M. I). 

 British Columbia. 



Not uncommon in the Pleistocene, particularly in the deeper part 

 of the Leda clay. Less common recent. I observed in the Riviere- 

 du-Loup gatherings a small individual of this species with the internal 

 pipe at the aperture characteristic of Entosolenia, which is also some- 

 times observed in recent specimens. 



Truncatulina lobatula. 



Fossil Leda clay, Labrador ; Riviere-du-Loup ; Anticosti. 



Recent Gulf St. Lawrence, very common 30 to 50 fathoms. British 

 Columbia. 



This species is much less common in the Pleistocene than in the 

 recent. 



Orbulina universa. 



Fossil Leda clay, Montreal ; Riviere-du-Loup ; Labrador. 

 This may be regarded as a rare and somewhat doubtful Pleistocene 

 fossil. It has not yet been recognized in the Gulf of St. Lawrence. 



Globigerina bulloides. 



Fossil Riviere-du-Loup ; Anticosti. 



Recent Gulf St. Lawrence, more especially in the deeper water, 

 where it is common. It is very rare in the Pleistocene. 



Pidvinulina repanda. 



Fossil Montreal, Leda clay ; Riviere-du-Loup ; Murray Bay ; 

 Labrador ; Quebec ; Portland (Maine). 



Recent Gulf St. Lawrence, 30 to 313 fathoms. G. M. D. 



Somewhat rare both in the Pleistocene and recent, and of the small 

 size usual in the arctic seas. 



Polystomella crispa. (Var. striatopunctala). 

 (Var. arctica). 



Fossil Montreal, Leda clay ; Labrador ; Riviere-du-Loup ; Murray 

 Bay ; Quebec ; Portland (Maine) ; St. John, N.B. 



Recent Gulf and River St. Lawrence, 30 to 40 fathoms. G. M. D. 

 British Columbia. 



Very common, especially in depths of 10 to 40 fathoms. This is by 

 far the most abundant species in the Pleistocene deposits, as it is also 

 in all the shallow parts of the Gulf of St. Lawrence at present, and
