18G9.] AVIIITEAVES — CANADIAN MARINE MOLLUSCA, 53 



Troplwn clathratus Linn. — One taken with T. Gimneri. 

 Triclwtropis horealis Brod. et Sow. 



Admete virklula 0. Fabr. — The two last species were fine, and 

 frequent in 30 to 40 fiithoms. 



CEPHALOPODA. 



? Lollgo ilhcebrosa Lesuer ; — Abundant ; is used by the fisher- 

 men largely as a bait for cod. 



Among other invertebrates dredged here were Metridium 

 marginatum Edw. et Haime, Alci/oniion ruhlforme Ehrenb., 

 EcJdnarachnius parma Linn., OpkioplioKs aculeata Lutk., 

 Oph!ogli/pha rohusta, and 0. Sarsii, with other commoner forms, 

 and some fine sponges. 



It is thought desirable to place on record a list of the sea 

 shells known to inhabit the River and Gulf of the St. Lawrence, 

 north of New Brunswick, and south of north-eastern Labrador. 

 The species enumerated in the preceding list are included, and 

 only unrecorded localities are given for rare species. My thanks 

 are due to Principal Dawson, to Drs. Stimpson, and P. P. 

 Carpenter, and to Messrs. S. Hanley and J. G. Jeffreys, for their 

 kind critical assistance in the identification of difiicult species. 

 At the same time, having carefully compared the Canadian shells 

 with Moller's types in the British Museum, and in the cabinets 

 of Messrs. Hanley and Jeffreys, this and the preceding list must 

 be regarded as the expression of my own individual judgment ou 

 the several species.
