We have taken this new and rare fliell by dredging ia 

 Salcomb bay ; and have found it of a very inferior fize on 

 other parts of the fouth coafl of Dcvonjliirey particularly 

 at Torcrofs ; and once on Studland beach, in Dorfetjliire. 

 It has alfo been found at Weymouth, by Mr. Bryer. 



The animal, like that of the preceding fpecies, fo com- 

 pletely envelopes the (liell, that not the leaft appearance of 

 it is to be difcovered, either in a dead or livinsr ftate. It 

 is of an oval fliape, and of a reddifli, or brown colour ; 

 foraetimes nearly white: has much the appearance of a 

 contra6ied, naked Limax, and indeed feems to be nearly 

 allied to that clafs pf animals. 



The upper part of the body is very convex, covered 

 with a thick, tough, ligamentous fl<in, that conceals the 

 flieil, and extends downwards on each fide, where the 

 edges are thin, and detached from the body : in the fore 

 part of this margin is dijinus, through which the animal 

 protrudes an appendage, or arm, fomewhat flat, a quarter 

 of an inch in length, the extremity of which is bifid; the 

 lower divifion terminating in a thread-like procefs. The 

 body of the animal beneath, or rather the Sujlentaculum^ 

 is oblong and flat, with a deep depreflion between it and 

 the marginal (kin : the head is furniflied with two fmall, 

 white tenlacula, at the bafe of which, are two fmall black 

 eyes. 



The {hell may be felt under the fl^in on the back, but 

 is difficult to be extratted without breaking, from the 



extreme
