52 THE CANADIAN NATURALIST. [Marcll 



Aporrhais occidentalis Beck : — Alive, with the two preceding. 



Mcnestlw alhula Moll. — Three living ; adult specimens were 

 taken on a stone, from about 20 fathoms water. 



Velutina (^MorvUUa^ Zonata Gould : — Three examples taken 

 on stones in deep water. 



Velutina liallotoidea Miill. — One taken living, with the above. 



Natica affinis Gmelin (= N. clausa Brod. et Sow.): — Fine, 

 in about 40 fathoms. 



Lnnatia Groenlandlca Mtjll. — Very large, living with the

Lunatia hews Say : — Frequent in sandy parts of Gaspt^ Bay, 

 but rare opposite Grande Greve. 



Pleurotoma bicarinafa Couth : — Rare, in 30 to 50 fathoms. 



Bela nohilis Moll. — A few living, at the same depth as the 

 above. 



Bela exarata Moll. — One living, in about 40 fathoms. 



Bela scalaris Moll. — In mud, at from 30 to 50 fathoms. I 

 regard these three as good species, distinct from the British B. 

 turrlcula, of which I have never seen typical specimens in 

 Canada.

 fathoms mud.

 F. rufus Gould and B, VahlU Moll.) : — With the preceding, 

 but rare. 



Nassa trlvlttata Say : — Living, a little above the village of 

 Gaspe Basin, where the water is brackish. 



Buccinuni undatum Linn. — Several varieties of this species 

 were dredged in deep water. I regard the Buccinum u/ulidatum 

 of MoUer and the B. Lahradorense of Reeve, as varieties of this 

 protean mollusc. 



Buccinum tenue Gray (= B. scalariforme Moll.): — Alive, in 

 60 fathoms mud. 



Buccinofusus Kroyeri Moll. sp. — One living specimen, with 

 the preceding ; it is the Buccinum cretaceum of Reeve and the 

 B. Donovani of Prof. Bell's list. 



Chrysodomus decemcostatus Say : — One dead immature speci- 

 men was dredged in deep water. 



Chrysodomus pygmceits Gould : — Not rare, living in about 

 30 fothoms.
