210 Natural History of the 



Pagurus Bernhardus. — Abundant in shells of Natica, Bucci - 



QUID, FUSUS, &C. 



Homarus Americanus. — Lobsters are rare on the south-east 

 side of the St. Lawrence, but very abundant on Anticosti and in 

 the Bay of Chaleur as far up as Dalhousie, and Principal Dawson 

 mentions them as being likewise abundant in Ga>pe Bay. 



Astacus Bartonii. — The common crawfish is abundant in the 

 Mat-ipedia, Restigouche and Metis Rivers, and in 1857 I found a 

 specimen just below the high falls of the Ouiatchouan, which emp- 

 ties into the south side of Lake St. John. 



Crangon vulgaris. — Although the common shrimp is abundant 

 in the St. Lawrence, and lar^elv devoured bv the cod, the fisher- 

 men have not yet got into the way of using them for bait. 



C. sculp tus. — A specimen corresponding nearly with Bell's des- 

 scription of this, was caught in the dredge, off Cape Cliatte. 



Hippo/yte (?). — A shrimp of this genus was dredged near 

 Metis ; but the specimen is so much damaged, that the species is 

 not satisfactorily determined. 



Orchestia (?). — A species of beach-flea swarms in all the pools 

 left by the receding tide. 



MOLLUSC A. 

 Gasteropoda (Marine). 



Fusus scalariformis. — Peter River, Ste. Anne and Marcouin,iri 

 stomachs of haddock and flounders, and living specimens dredged 

 in 60 fathoms at the latter place. 



F. Islandicus. — Trent, Ste. Anne and Marcouin, not common. 



F. tornatus (Gould). — Parts of large individuals were found on 

 the shore at Rimouski, and complete specimens near Ste. Anne. 

 This is the same species as the one so common in the Post Plio„ 

 cene clays near Montreal. 



F. decerncostatus. — Two good specimens in a collection of 

 shells brought from near Cape Gaspe by Sir W. E. Logan in 

 1844. 



F. rvfus. — Numerous specimens from stomachs offish at Ruis- 

 seau Vallee. 



F. Bamjjius. — Same source. 



Pleurotnma bicarinata ? — One specimen from same source. 



Bnccinvm undutum. — Whole coast from Riviere du Loup 

 downwards; very abundant at low tide, and constitutes one of the 

 principal articles of bait used by the fishermen after the capelin 

 have disappeared.
