Gen. 5. Solen, Razor -Jheath. 
Gen. Char . — The animal inhabiting this fhell is an af- 
cidia : fhell bivalve, oblong, open at both ends ; 
hinge with a fubulate reflected tooth, often double, 
£nd not inferted in the oppofite valve. 
Species. 
* 1. S. linear, firaight, roundifh ; one end margined ; 
hinge with a Angle oppofite tooth in each valve. Eu- 
ropean and Indian feas, Caermarthenfliire, Wey- 
mouth. 
* 2. S. linear, firaight, one hinge 2-toothed. Euro- 
pean and Indian feas. Length 1 inch, breadth 8 inches. 
Common on the fhores of Britain, where it is employed 
as food. — This fpecies lurks in the fand, near low-water 
mark, in a perpendicular diredlion, and when in want 
of food, they raife one end above the furface, and pro- 
trude the body a confiderable way out of the fhell. At 
the approach of danger they dart deep into the fand, as 
far even as to the depth of two feet ; and the place is 
known by a fmall hollow on the furface. They are 
fometimes taken by digging them out of the fand, or by 
Ariking a barbed dart into their bodies.
