beneath the sea. We see no good reason for this conclusion, as 
the shells got from it are all varieties of existing species. That 
Mya Uddevallensis has net been brought up alive on the fisher- 
men’s lines, may be accounted for from its habit of living buried 
in the sand. The specimens obtained appear to have been at- 
tached to the byssus of Modtola vulgaris, a not unusual mode of 
getting shells from deep water, but such are generally in a bad 
state.

Common on some of our sandy beaches, where it lives in the 
sand near low-water mark. It is plentiful at Newbiggin and in 
the north of Northumberland, as well as at Hartlepool and Sea- 
ton; but it is not found on Cullercoats or Whitley sands, and 
rarely in the north of Durham. Capt. Brown found a specimen 
at Holy Island measuring twelve inches.
