GEN. CRENILABRUS. THE CORKLING. 299 



also in the Baltic, and on the British shores, where 

 It is usually shorter : Mr. Thompson has detected 

 it on the coast of Ireland. — The mouth of the Cork- 

 wing is small ; the teeth are regular ; the denticu- 

 lations of the pre-opercle very strongly marked ; the 

 lateral line is straight till it reaches the posterior 

 part of the dorsal, where it deflects almost at right 

 angles, and again turns at a similar angle to go to 

 the tail, dividing it equally. The colour, according 

 to Dr. Parnell, is reddish brown on the back and 

 sides, tinged with greenish blue, and marked by 

 twelve or fifteen longitudinal lines of a darker shade ; 

 the abdomen is pale orange-red ; the dorsal, anal, 

 and caudal fins green, with spots and stripes of 

 orange-red. This species is readily distinguished 

 from all the other British, by the black spot at the 

 termination of the lateral line. All the specimens, 

 says Dr. Parnell, taken at Brixham, Devonshire, 

 were nearly of equal dimensions, not exceeding four 

 and a half inches in length, which appears to be the 

 average size ; though on two occasions he observed 

 them larger, one measuring seven inches and the 

 other eight in length. " They feed," adds that ac- 

 curate Naturalist, " on shells and Crustacea; but 

 on some occasions I have observed their stomach 

 filled with vegetable matter and the roe of other 

 fishes."
