94 THE CANADIAN NATURALIST. [Vol. vii=- 



Botri/Uus, a purple species, distinct from B. Goiddli, VerrilL 

 Attached to Flustra Barleei :?, Busk, from 96 fathoms in 

 Trinity Bay. 



Several examples of Amouvcecium glahnim, Verrill, were col- 

 lected in and just outside of Gaspe Bay, where I had previously 

 dredo'ed it in 1869. 



MOLLUSCA. 



In the 'Canadian Naturalist' for 1869, I published a cata- 

 logue of 114 species of marine Mollusca inhabiting the Gulf of 

 St. Lawrence, to the north of the Bay of Chaleurs. We now 

 know localities for 150 species which inhabit the region in ques- 

 tion. The shells collected last summer have been carefully 

 studied ; and the following is a list of some of the most interest- 

 ins: amono; them*. 



Terehratula septentrional is, Couth. In 112 fathoms, stones, 

 off Charleton Point, Anticosti, and in 212 fathoms to the S.S.E. 

 of the east end of that island. 



Terchratella Spitzhergensis, Davidson. 38 fathoms, stones, off 

 Cap-Rosier lighthouse, alive, adult, and frequent ; 96 fathoms, 

 in Trinity Bay, one young, but living example; 112 fathoms, off 

 Charleton Point, Anticosti, one dead, adult. Most abundant in 

 somewhat shallow water. 



Pecten Grcenlandicus, Chemn. Take alive in several localities 

 in from 160 to 250 fathoms,- mud. 



Lima sulculus, Leach. Fine specimens in 38 fathoms, off 

 Cap-Rosier lighthouse. 



Area pectunculoides, Scacchi (=^4. rai'identata, Searles Wood.) 

 Dredged on the north shore of the St. Lawrence, also between 

 Anticosti and the south shore, in 160 to 170 fathoms. The 

 specimens were often living, and of large size for the species. 

 New to the western side of the Atlantic. 



Area glacialis, Gray (==A. raridentata, var. major, Sars). 

 A few dead examples of this shell were taken with the preceding 

 one. 



Yoldia (? Fortlandia) thracia^formis, Storer. One living 

 specimen occurred in 212 fathoms, S.S.E. of the east point of 

 Anticosti, and a dead, but perfect one, in 125 fathoms, off Cap 

 Rosier. 



* I am indebted to Mr. J. Gwyn Jeffreys, F.E.S., for the determin- 

 ation of those species to which an asterisk is affixed.
