258 THE ICE AGE IN CANADA. 



Tritonofusus Kroytri. Miiller. 



Fossil — Rivivre-du-Loup ; Labrador (Packard); New Ricliinou<l ; 

 River Charles, N.B. (Matthew). 



Recent— Little Meti.s ; Gnlf St. Lawrence and Arctic seas. First 

 recognized as this species l)y Mr. Wliiteaves. Specimens from Spitz- 

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

 Packard found it not unconnnon at Labrador, l)ut it seems rare in other 

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

 appeared as B. cretdceum (Reeve), wliich seems to ))e an error. Alaska 

 (Dall). (I'late VL, fig. 3.) 



Sipho ^^2^itzbcrglnsis. Reeve.* 



Fossil — Montreal (small and rare). 



Recent — Little Metis; Murray Ray to Gasp(5 ; also Spitzbergen, 

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



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

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

 beautiful species, evidently ipiite distinct from S. Mandictis. From 

 Middendortl''s description and figure, I think it not iTiiprobable that it 

 may be the same with his Trito/iinm Schtintnricum, from the sea of 

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

 at ilurray bay, until tliese sheets were going tiirougli the press. 

 Young specimens are renuirkably like in form aiul sculpture to 

 FascioUtria ligtitd, which 13 found with it at Murray l)ay. Reeve's 

 figure in Belcher's " Last of the Arctic Voyages," well rein-esents our 

 specimens, though iieriiaps a very little coarser in sculpture. 



Xeptunea doipecta, L. 



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

 Riclnnond, 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 

 Fiisiis tonidfiin of Gould to F. de-tjiectUK of Linnanis, as described by 

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

 Crag are considered by S. Wood as varieties of /'. (iiitiquuti.f Dr. P. 



* Verrill calls this 8ipho lividus, and holds that it is distinct from 

 Fustis Spitzberc/ensin, Reeve. (J. ¥, W. ) 



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

 from the Arctic regions of the North Pacific.
