PLEISTOCENE FOSSILS. 251) 



1*. Carpenter thinks that tiiis and the British P. (intiqnus may prove 

 to belong to one very variable species. The /'. (h.'^jnctiis is an Arctic 

 form. The F. loDiatus is recent, and is the form now found in the Gulf 

 and Kiver St. Lawrence, where it is much larger and better developed 

 than in the I'leistocene. C. (Icctmcostdfiis is more southern. 



Neptunea (lecenicoxf(tl(t. Say. 



Fossil — Portland, Maine. 



Kecent — Magdalen Islands and (Jaspu ]5ay (Whiteaves) ; coasts of 

 Nova Scotia and New England. 



This species has not yet been found in the Pleistocene of Canada, 

 where it is represented by C. tornatiis. There are still two opinions as 

 to whether Say's species is identical with C. /yrutus (Mart.) =Midden- 

 dorffii (Cooper) from the Pacific coast. The latter is variable, and 

 graduates towards tormUuH (Gould), but the living New England shells 

 are tolerably constant in character. 



Tvophon scalarifornie. (iould. 



Fossil — Montreal ; Murray Bay ; Rivir-re-du-Loup ; Labrador. 



Recent — (ireenland (Hayes) ; Little Metis; Murray Bay; Nova 

 Scotia (Willis) ; (iaspe and North Shore (Whiteaves). 



It is a rare shell in the Pleistocene, but of large size and in good 

 condition. 



Trophoii cluthralum. Linn. 



Fossil— Montreal ; Murray Bay ; Riviere-du-IiOup ; Anticosti ; also 

 glacial beds of Europe. 



Recent — Riviere-du-Loup ; Little Metis ; Greenland and Arctic seas 

 generally ; Labrador ; (lulf St. Lawrence (Whiteaves). The allied 

 species or variety, T. Ounneri, has been found living at Gaspe by 

 Whiteaves, and occurs at Little Metis, but not fossil as yet. British 

 Columbia ; Alaska (Dall).

Serpula vermicularis. Linn. 



Fossil— Montreal ; Murray Bay ; Riviere. du-Loup. 

 A small species of Serpula, apparently the above, though perhaps 

 the determination may be regarded as uncertain. _
