1869.] WHITEAVES — CANADIAN MARINE MOLLUSCA. 49 



dredged by myself at Grande Greve, and, 2nd, a catalogue 

 of all the marine mollusca known to inhabit Lower Canada at 

 the present date. 



Grande Greve is a fishing station on the North-east side of 

 Gaspe Bay, and is sheltered by the narrow strip of land of 

 which Cape Gaspe is the extremity. The rocks of Oriskany 

 sandstone here dip slopingly towards the sea, which deepens very 

 rapidly from the shore, so that but few shells can be collected 

 unless the dredge is used. A fortnight was devoted to a careful 

 examination of this particular spot, and seventy-five species were 

 procured, as follows : — 



PALLIOBRANCHIATA. 



RhynclionelJa psittacea Gmelin : — Frequent, alive on stones in 

 from 10 to 20 fathoms. 



LAMELLIBRANCHIATA. 



Anomia ephipjnum Linn. — On stones and shells with the 

 above ; the var. aculeata frequent. 



Amusmm tenuicostatum Mighels (= Pecten Magellanicus 

 Lam.): — Alive in 1 to 10 fathoms. 



Pecten Islandlcus Chemnitz : — Living in from 5 to 40 fathoms 

 water. 



Nucula tenuis Montagu, and var. expansa (= iV. expansa 

 Eeeve) : — Alive in 40 to 50 fathoms mud. The Nucula infiata 

 of Hancock, from Greenland, etc, is apparently only a variety of 

 this species, and is probably the same as N. expansa lieeve. 



Nucula delphinodonta Migh. : — With the above, but much 

 more abundant. The shell is covered with a ferruginous coat 

 like the British Lucina ferniginosa. 



Leda permda Miiller : — Six fine living specimens in 50 fathoms 

 mud. 



Leda minuta Miill. — One, living, with the above. 



Yoldia myalis Couthuouy : — Rare, with the two preceding ; 

 but not infrequent in the stomachs of flat fish caught oft' Grande 

 Gr^ve. 



CrencUa glandula Totten : — A few taken living in from 20 to 

 40 fathoms. 



CrencUa decussata Mont. (== C. clcercula Moll.) — Abundant, 

 living in mud, in from 20 to 60 fathoms. Quite distinct from 

 the preceding, but larger than the average of British specimens.
