272 THE CANADIAN NATURALIST. [Sept. 



Wood bored bj a species of Limnoria (?) was dredged off St. 

 George's cove, and a large parasite isopod crustacean was 

 found attached to cod fishes. Special attention was paid to the 

 smaller Crustacea, of which about twelve species were taken. 

 Among these were f lur species of shrimp, which appear to be 

 Crangon vulgaris, (the common English shrimp,) and another 

 species, also ffippolt/te Fabricii and Gaimanlii. In addition to 

 these, specimens of Gammarus locasta, Alauna Goodsiri, and 

 Caprella septentrionalis were collected ; also several undetermined 

 Amphipods, and two species of Entomostraca, one of which is 

 probably the Cyprldlna excisa of Stimpson. Fine examples of 

 many species of Polyzoa and tunicates were dredged ; these are 

 in the hands of Principal Dawson for study and determination. 

 Among the latter Dldannium rosemn, Boltenia Bolteni, and two 

 species of Cynthia have been recognized. In a previous paper 

 published in this journal (vol. 4 p.p. 48-57), a list was given of 

 all the marine mollusca then known to inhabit Lower Canada. 



In addition to the 103 species there enumerated, the following 

 have since been met with : — 



Macoma inflata, Stimpson. Gasp^ Bay. 



Cochlodesma Leanum, Con. Near Douglastown. This is the 

 most northerly locality yet recorded for this species, 



Thracia Conradi, Couthuoy. Near Grande Greve. 



Teredo dilatata ? Stimps. Gaspe Bay. 



Philine lineolata, Couth. Gasp^ Bay. Principal Dawson. 



Utriculus ? 



Diaphana debilis? Gould. 



Margarita argentata? Gould. 



Rissoa, an additional strongly marked species, at present 

 undetermined. 



Mamma immaculata, Totten. Gasp^ Bay. 

 " nana, Moller. " " 



Amaura Candida, Moller. " " 



Bela. Two additional species, undetermined. 



Besides these 14 additional species, the following new localities 

 were observed for scarce shells : 



Leda minuta. Mull. Plentiful off Cap Rosier village. 



Crenella pectinula, Gould- Off Grande Greve. 



Astarte lactea, Brod and Sow. Alive, between Ship Head and 

 Cape Bon Ami, four miles from shore. This is the shell
