Family Anomiadce. 

 Anomia aculeata, Miiller. 



Anomia aculeata, Miiller (1706) ; Gmelin (1792) ; et auct. 



Widely distributed in and to the north and south of the Gulf of St. 

 Lawrence, at depths of less than 100 fathoms. The little smooth Anomia 

 of this region that has been hitherto referred to A. ephippium, is regarded 

 by Verrill as most probably a form of A. aculeata in which the aculeate 

 scales are more or less abortive.

 Ostrea Canadensis, Lamarck (1819). 



" In the Gulf of St. Lawrence, oysters are usually found in very shallow 

 water, nearly always in depths of less than three fathoms, in sheltered bays 

 or mouths of rivers. In New Brunswick, as has been shown by Perley, 

 they range from Caraquette to Baie Verte. The writer was informed by 

 Captain Purdy that oysters have been taken up on the flukes of anchors, in 

 7 fathoms water between Little and Big Caraquette banks, in the Baie des 

 Chaleurs. On the coast of Prince Edward Island, oysters are found, in 

 suitable localities, from Pinette River to the west point, on the Northumber- 

 land Strait side ; and in Malpeque or Richmond Bay, from Cascumpeque to 

 New London, on the northern. In Cape Breton they appear to be confined 

 to Bras d'Or Lake and its tributaries, whei'e the oyster region extends from 

 St. Ann's to Mira River and St. Peter's Bay. The few oysters to be met 

 with off Nova Scotia occur at Jeddore Head, twenty or twenty-five miles 

 east of Halifax Harbour, also Country Harbour, St. Mary's River, and 

 Lipscombe Harbour, Guysboro' Co., on the outside ; and Pictou Harbour,
