40 SALMOWID^. 



tudinal series of scales between the lateral line and the base of the 

 ventral. The transverse series descending forwards from behind 

 the adipose fin to the lateral line is composed of sixteen scales. All 

 the scales are obtusely rounded behind. 



Back greenish-brown ; sides silvery ; belly dark brown ; scattered 

 black, X-shaped spots, irregularly distributed, and sometimes con- 

 fluent so as to form an irregular small blotch, occupying the sides 

 above and below the lateral line. Fins immaculate, with a blackish 

 tinge.

The greatest depth of the body is below the origin of the dorsal fin, 

 and is contained four times and two-thirds in the total length (the 

 caudal not included) ; the length of the head is a little less than one- 

 fourth of the same. The snout is moderately produced, conical, and 

 is contained once and three-quarters in the postorbital portion of the 

 head; the lower jaw is without a hook, and the mouth closes per- 

 fectly ; the maxillary is considerably longer than the snout, and ex- 

 tends far beyond the vertical from the posterior margin of the orbit ; 

 the width of its broadest part is less than the diameter of the eye. 

 The dentition of the jaws and palate is perfect, the teeth of the 

 mandible being rather stronger than those of the intermaxillury and 

 much longer than those of the maxillary und palatine bones : of tho
