 = nifida bracfeata, Govild; (according to Carpenter.) 



Common everywhei-e in sand between tides. I have taken at 

 Victoria an unusually large form which at first I was tempted to treat 

 as a distinct species, but Dr. Dall who kindly examined it considers it to 

 be merely a northern variety of Californica.

Never yet found by us in any numbers but a])parently generally 

 distributed. Living specimens have been taken at the (^ueen Charlotte 

 Islands and Victoria ; dead shells at Comox ( " verj' large " Harvey), 

 Clayoquot Sound and elsewhere.

The generic name Necera, Gray (1884), is said to be preoccupied in 

 Diptera. 



C. pectinata is recorded b}' Carpenter from Puget Sound (1 specimen, 

 Dr. Kennerley). It seems to be quite a common shell with us, having 

 been taken in from 10 to 20 fathoms, in all the localities in which we 

 have dredged. The shells are usually somewhat less than half an inch 

 in length, but Mr. Whiteaves records an extraordinarih' large example 

 from Quatsino Sound measuring 21 x 13 mm.
