216 Natural History of the 



Point Levi, all along the south-east side of the St. Lawrence from 

 Riviere du Loup to Gaspe, and in nearly every place examined 

 in the interior of the peninsula or on the Ristigouche. 



AcephaJa (Marine). 



Pholas crispata. — Dead specimens were found at Bic Harbour, 

 Rimouski, and near the Trent. 



Saxicava rugosa. — Abundant living in stiff mud at Les Islets 

 and at Ste. Anne in Limestone, nullipore and the roots of a large 

 green seaweed with perforated fronds (Agarum Turneri). Empty 

 specimens were collected at Cape Chatte, Marsoni and Glande. 



Mya arenaria. — Found abundantly in every favourable locality 

 along the whole coast. In ascending the river they gradually 

 become smaller as they approach the fresh water, and probably 

 extend only a short distance above Riviere Ouelle, where, after 

 searching for some time I found only one small living specimen. 

 In the Bay of Chaleur they seem to be as large as on the north 

 coast of Gaspe. 



M. truncata. — Fresh valves numerous along the shore at Bic, 

 Rimouski and St. Luce. Numbers of fine specimens found at 

 different places between Metis and the Trent ; valves dredged at 

 Ste. Anne and Marcouin. 



Glycimeris siliqua. — CapeChatte,RuisseauVallee and Marcouin. 



Odeodesma hyalina. — Ste. Anne, several very fine specimens 

 from stomachs of flounders. 



Machaera costata. — Very common at Rimouski. 



Solen ensis. — Bic, Rimouski, St. Luce, Cape Chatte, Ste. Anne, 

 and extremely abundant at Grande and Peter Rivers. 



Tellina proximo, (calcarea). — Ste. Anne, Ruisseau Vallee and 

 Marcouin, stomachs of haddock. 



T. Groenlandica. — More or less abundant along the whole coast. 

 In 1857 I found this species at Bay St. Paul, on the north-west 

 side of the St. Lawrence only, about 55 miles below Quebec, 

 which is probably the nearest approach of the living marine shells 

 to their fossil ancestors in the Post Pliocene deposits in the Ot- 

 tawa Valley, some of which are nearly 400 miles distant. 



Mactra ovalis (ponderosci). — First met in Bic Harbour, but 

 lecomes very abundant at Rimouski, 12 miles farther down. 

 Occurs at Metis and Ste. Anne, and in the coves at the mouths of 

 Marcouin, Glande and Mont Louis Rivers. 



Mesodesma arctatum. — Dead specimens were found as far up
