No. 3.] DAWSON — I'OST-PLIOCENE. 255 



Truncafulina lohulata. 



Fossil — Lcda clay, Labrador ; Pviviere-du-Loup. 

 Recent — Gulf St. LuT^'rence, very common 30 to 50 futlioms. 

 This species is much less common in the Post-pliocene than in 

 the recent. 



Orhidlna unicersa. 



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



This may be regarded as a rare and somewhat doubtful Post- 

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

 Lawrence. 



Glohigerina huUoides. 



Fossil — Riviere-du-Loup. 



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

 water, where it is common. It is very rare in the Post-pliocene. 



Palvinulina 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 Post-pliocene and recent, and^ of 

 the small size usual in the arctic seas. 



Folystomella a'lsjxi. — (Yar. Striatojmncfafa) . 

 (Yar. Arcfica.) 



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. 



Yery common, especially in depths of 10 to 40 fathoms. This 

 is by far the most abundant species in the Post-pliocene deposits, 

 as it is also in all the shallow parts of the Gulf of St. Lawrence 

 at present, and also in the Arctic Seas, according to Parker and 

 Jones. It is the only species yet found in the Boulder-clay of 

 Montreal, and this very rarely.
