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 UddevalleQisis has not 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 Modiola vulgaris, a not unusual mode of 

 getting shells from deep water, but such are generally in a bad 

 state.

1. S. siliqtta, Linn. 



Solen siliqua, Mont. Test. Brit. 46. 

 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. 



2. S. ENSis, Lin n. 



Solen ensis, Mont. Test. Brit. 48.

 last.
