fPecten vitreus, Gmelin (1792) ; and Dillwyn (1817) ; Dall. 

 Pecten vitreus (Chemnitz) G. O. Sars (1878). 

 Camptonectes {PaUiolum) vitrcum, Verrill (1897). 

 Camptonectes vitreus, Dall (1898). 



" Common on the deep-water fishing grounds off Nova Scotia and New-

Pecten (Cyclopecten) pustulosus, Verrill. 



Pecten pustulosus, Verrill (1873).

 Pecten imbrifcr, Dall (in part) 1886 ; but not of Loven. 

 Cyclopccten pustulosus, Verrill (1897). 



" The original specimens " of F. pustulosus were " from south of George's 

 Bank, 430 fathoms, and Gulf of Maine, 150 fathoms," where they were 

 dredged by the U. S. Fish Commission in 1872. "It was afterwards 

 dredged by us, in 1877, in the Gulf of Maine, 115 fathoms, and off Nova 

 Scotia, in 190 fathoms, associated with the non-pustulose form" (Verrill). 



Family Limidce. 



LiMATULA SUBAURICULATA (Montagu). 



Pecten subauriculata, Montagu (1808). 



Ostrea subauriculata, Turton (1816). 



Lima subauriculata, Turton (1822). 



Lima sulcata, Brown (1827) ; and Moller (1842). 



Limatula subauriculata, Searles Wood (1839). 



North shore of the Gaspe peninsula at St. Anne des Monts (Bell, 1858). 

 Off Cap des Rosiers in 38 fathoms, stones, one living adult specimen ; and 

 about half way between East Cape, Anticosti, and the Bird Rocks, in 313 

 fathoms mud, a fragment of one of the valves ; both dredged by the 

 writer, the former in 1871 and the latter in 1872. 



Limatula sulculus, the Lima sulculus (Leach) Moller, is stated by Willis 

 to be very rare at Sambro and Sable Island, N.S. ; and Packard says that 

 he dredged several specimens of it near Caribou Island, in 15 to 50 fathoms. 

 But, it is not quite clear that the Canadian shells which have been referred 

 to L. sulculus are really distinct from those that have been identified with 

 L. subauriculata. Jeffreys unites L. sulculus with L. subauriculata.
