2. c^LLORnYNcnus. 351 



the first dorsal and the vcntial fin is great, which causes the pectoral 

 fin to terminate much in advance of the ventral; 'which is not the 

 case in any of the allied species, since in monstrosa the pectorals at- 

 tain to the posterior extremity of the veutrals, and in the American 

 species to the origin of those fins. Caudal fin very small, and ter- 

 minating in a minute filament. The anterior (cephalic) appendages 

 present five spines on the inner surface ; in Ch. coU'iei these organs 

 have only two supines. Finally, the posterior appenda.i^fs arc tripar- 

 tite, as in Ch. monstrom, hut the division of the three portions takes 

 place at two-thirds from the base ; moreover the cylindrical portion 

 is larger, and presents a form diff'erent from that in the others.

Snout with a cartilaginous jirominencc, terminating in a cuta- 

 neous flap. Two dorsal fins, the anterior with a very strong and 

 long sj)ine. Extremity of the tail distinctly turned n])wards, with

 the caudal, short and deep.

The second dorsal fin elevated in front. Pectoral fin very large, 

 extending generally to, or even beyond, the base of the ventral. 

 Claspers subcylindrical, ^dth a channel along the interior, opening 

 by a lateral slit. Adult with an obscure blackish lateral band. 

 Young with the upper parts black, and with whitish bands and spots. 

 The young have also a double series of very small dermal spines on 

 the crown of the head, and on the back of the trunk and tail ; these 

 spines are also sometimes found in half-grown and adult examples, 

 in which, however, they are hidden in the skin.
