The margined stone cat lias a moderately elongate and low 

 body, its width greater than its depth, and the least depth of 

 the caudal peduncle about three fourths the greatest depth of 

 body. The head is rather long and depressed, one fourth of 

 total without caudal, the snout short and rounded. The eye 

 is small, its length one half the width of interorbital space and 

 little more than one half the length of snout. The lower jaw 

 is slightly shorter than the upper; the width of the mouth equals 

 postorbital part of head. The width of the maxillary band of 

 teeth equals one third the length of head; there is no extension 

 backward. The maxillary barbel reaches nearly to the end of 

 the head. Six short gill rakers below the angle of the first gill 

 arch. The dorsal origin is about oyer the middle of the space 

 between the pectoral and yentral origins; the length of the 

 dorsal base equals the distance between the eyes, and also the 

 length of its spine. The longest ray is half as long as the 

 head. The yentral reaches beyond the yent and almost to the 

 anal origin, its length half the head. The pectoral does not 

 reach to the yentral origin, its spine half as long as the 

 head, rough along its front edge and coarsely serrate behind. 

 The adipose fin is little deyeloped; it begins oyer the anal origin 

 and is continuous with the caudal. The anal origin is nearly 

 midway between the pectoral origin and the base of the caudal; 

 the base is scarcely two ninths of total length without caudal; 

 the posterior and longest rays are scarcely one half as long as 

 the head. The caudal is rounded. D. I, 7; A. 17; V. 10; P. I, 9. 

 In spirits the upper parts are dark brown, the belly and under
