348 Mr. J. F. Whiteaves on Bee-p-sea Dredging 



TUNICATA. 



The following is a list of the few species of this order at 

 present identified bj Prof. A. E. Verrill : — 



Ascidiopsis complanatus { = Asctdia complanata, Fabr.). In 



212 fathoms to the south-east of the east point of Anticosti. 

 Eugyra pilidarisj Verrill. In 50 fathoms off the St. John's 



River, Mingan. 

 Botryllus^ a purple species, distinct from B. Oouldii, Verrill. 



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



Trinity Baj. 



Several examples of Amouroucium glabrunij Verrill, were 

 collected in and just outside of Gaspe Bay, where I had pre- 

 viously dredged 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 question. The shells collected last summer have been 

 carefully studied ; and the following is a list of some of tho 

 most interesting among them *. 



Terehratula septentrionalis^ 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. 



Terebratella 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. Taken 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 {=A. raridentata^ Searles Wood). 

 Dredged on the north shore of the St. Lawrence, also be- 

 tween 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 pre- 

 ceding one. 



* I am indebted to Ma-. J. Gwyn Jefireys, F.R.S., for the determination 

 of those species to which an asterisk is affixed.
