258 THE ICE AGE IN CANADA. 



Tritonofusus Kroyeri. Moller. 



Fossil Riviere-du-Loup ; Labrador (Packard) ; New Richmond ; 

 River Charles, N.B. (Matthew). 



Recent Little Metis ; Gulf St. Lawrence and Arctic seas. First 

 recognized as this species by Mr. Whiteaves. Specimens from Spitz- 

 bergen in Mr. McAndrew's collection are perfectly similar to ours. 

 Packard found it not uncommon at Labrador, but it seems rare in other 

 parts of the Gulf of St. Lawrence, In some previous lists it has 

 appeared as B. cretaceum (Reeve), which seems to be an error. Alaska 

 (Ball). (Plate VI., fig. 3.) 



Sipho Spitzbergensis. Reeve.* 



Fossil Montreal (small and rare). 



Recent Little Metis ; Murray Bay to Gasp< ; also Spitzbergen, 

 and probably Sea of Okotsk ; N.W. coast (Dall). 



Only one specimen occurred at Montreal, and was an unknown form 

 until I fortunately dredged a few specimens at Murray Bay. It is a 

 beautiful species, evidently quite distinct from 8. Islandicus. From 

 Middendorff 's description and figure, I think it not improbable that it 

 may be the same with his Tritonium Schantaricum, from the sea of 

 Okotsk. I was not aware that it had been found on our coast, except 

 at Murray bay, until these sheets were going through the press. 

 Young specimens are remarkably like in form and sculpture to 

 Fasciolaria ligata, which is found with it at Murray bay. Reeve's 

 figure in Belcher's " Last of the Arctic Voyages," well represents our 

 specimens, though perhaps a very little coarser in sculpture. 



Neptunea despecta, L. 



Fossil Montreal ; Quebec ; Riviere-du-Loup ; Murray Bay ; New 

 Richmond, River Charles, &c., N.B. (Matthew) ; Labrador (Packard). 



Recent Little Metis, large specimens ; Gaspe Bay, large specimens 

 (Whiteaves) ; Labrador (Packard). 



This shell is not uncommon in the drift, and owing to its dense 

 texture is generally in good preservation. It ranges from the typical 

 Fusus tornatm of Gould to F. despectus of Linnaeus, as described by 

 Fabricius, from Greenland, and shells of similar form from the British 

 Crag are considered by S. Wood as varieties of F. antiquus. t Dr, P. 



* Verrill calls this iSipho lividus, and holds that it is distinct from 

 Fusus Spitzberyensis, Reeve. ( J. F. W. ) 



t The C. despectus of Reeve, however, is a very different species, 

 from the Arctic regions of the North Pacific.
