PLKLSTOCKNE FOSSILS. 247 



My only fossil specimen, obtained from Dr. Packard, is of the 

 small, elevated and depauperated variety so common at Murray Bay 

 and the north shore of the Gulf. It is curious that this common 

 modern species is so very rare in the Pleistocene. 



Lf./itfn cti'cn. Moller. 



Fossil — Montreal ; Rivicre-du-Loup ; Quebec ; Labrador ; European 

 l»ost-pliocene. (Plate VI., Fig. 9.) 



Recent— ( Jaspe ; Labrador ; Arctic seas generally ; and coast of 

 New England rarely. 



This shell is not at all rare, living at Gaspe, and fossil at Riviere- 

 du-Loup. Carpenter remarks that some of my Montreal specimens 

 have the characters of variety afriata of MiddendorfF from Siberia. 



Capx/itx Uitiiaricus. Lin. (rommodux ? Middendorff. ) 



Fossil— Point Levi, near (Quebec. One specimen only, found by 



Mr. (!unn and communicated )>y Dr. W. J. Anderson. Another and 



larger collected at Montreal (Prof. Kennedy) ; Scotland (Jeffreys). 



(Plate I., Fig. 14.) 



Recent— Spitzbergen ; (Jreenland; Norway. I have not found this 



sliell recent in the (>ulf of St. Lawrence. 



This species is I'ossil at Uddevalla, and is supposed to be the same 



with C. fdllax anc". C. oltfiqiiafiis of Wood from the English Crag. If 



a form of Cajxilus Umjaiintf, it has been repeatedly dredged alive off 



the New England coast, in deep water, by Verrill. 



Crepidida foriiicata, L, 



Baron de Geer, in his visit to Canada, 1891, was so fortunate as to 

 find at the Mile-End Quarries, in the Saxicava sand, a small specimen 

 of this shell, the first hitherto found in Canadian Pleistocene. 



Manjaritd hdkinn. Fabricius. 



Fossil — Montreal ; Murray Bay. 



Young specimens resemble M. antmiiiata of Mighels. Broad speci- 

 mens resemble M. Cfuiipdinihito, Morse. 



Recent— Arctic seas; (Julf of St. Lawrence; and coast of Nev 

 England. Also British Columbia. It is M. Arclka, Leach. 



Mar(farita argentnta. Gould. 



Fossil — Montreal. Rare. 



Recent — Labrador and (iulf St. Lawrence (Whiteaves) ; Murray 

 Bay; Gtaspe ; Riviere-du-Loup ; Little Metis; coast of New England
