2. CALLORIIYNCIITTS.

the first dorsal and the ventral 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 cxti'emity of the vcntrals, and in the American 

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

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

 present five spines on the inner surface; in Ch. col I lei these organs 

 have only two spines. Finally, the posterior appendages are tripar- 

 tite, as in Ch. monstrosa, but the division of tlie three portions takes 

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

 is larger, and presents a form different from that in the others.

Snout with a cartilaginous prominence, terminating in a cuta-

 long spiiie. Extremity of the tail distinctly turned upwards, with 

 a fin along its lower edge, but without one above. Anal fin close to 

 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. 

 Claspcrs subcyliudrical, \di\\ a channel along the interior, opening 

 by a lateral slit. Adidt 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 adidt examples, 

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