416 Newer Pliocene and Post Pliocene Deposits, 



Greenland. Fossil iu British pleistocene. Specimens found in 

 Montreal are of small size (Cor.) 



*Fusus tornatus, Gould. Montreal, between Saxicava sand 

 and Leda clay. This shell I suppose to be the F. Carinatus of 

 the lists ; but Dr. Gould assures me that it cannot be referred to 

 that species, nor to the F. despectus of Linnaeus, nor does it cor- 

 respond precisely with any of the varieties of the Trophon anti- 

 quum of Wood's crag Mollusca, but it is evidently closely allied 

 to that species. It corresponds exactly with Dr. Gould's descrip- 

 tion and figure*, and with recent specimens collected in Gaspe by 

 Sir W.E.Logan. I have about 50 specimens, andthey present no 

 well marked variety of form. Recent on American banks (Cor). 



*Fusus scalarifonnis, Gould, (Trophon Scalariforme, Wood); 

 very rare in Montreal, with F. tornatus. Recent Massachusetts 

 Bay and northward ; also in Spitzbergon, Behring's Straits and 

 North Sea. Fossil iu British crag. (Cor. and D. S. Cor.) (Fig.30.) 



*Fusus (Trophon) harpularius, Couthouy. Two specimens in 

 the collection of the Geological Survey, correspond with this 

 species. Recent in Massachusetts Bay. It closely resembles 

 Clavatula castanea of Wood's crag Mollusca. 



Trichotropis boreaUs, Brod. and Sow. Abundant at Montreal 

 in Saxicava sand. Recent Cape Cod and northward, also in Bri- 

 tish crag. (Cor). 



* Trichotropis arctica, Middendorfi". (Fig. 27) A single specimen 

 found at Logan's farm, Montreal, is referred by Dr. Gould to this 

 species, figured as Cancellaria arctica in the Malac, Rossica, and 

 found recent at Behring's Straits. 



*Admete [Cancellaria) viridula, Stimpson (Fig. 6) (C. Costelli- 

 fera, Wood's crag Mol). Montrenl, with Fusus tornatus, &c. 

 Larger than recent specimens, but resembles, according to Dr. 

 Gould, large specimens figured by Middendorfi. Recent Cape Cod 

 and northward. Fossil in British crag. (Cor.) 



Velutina zonata, Gould, (Fig. 10,) (V. Undata ? Wood's crag 

 Mol.) A single specimen from Logan's farm Montreal, given to 

 me by Arthur Ross, Esq., appears to belong to this species. It is 

 probably the same with that mentioned by Sir C. Lyell without 

 specific name. Recent Massachusetts Bay and northward (Cor.) 



Natica clausa, Brod. and Sow (Fig. Can. Nat., Vol. 1.) Plen- 



*The figures given by Sir C. Lyell, Prof. Emmons, and in Can. Nat. 

 Vol. 1, represent small specimens with the lip broken.
