caaiidl when laid backwards. Caudal as long as the head, deeply 

 forked, with the lobes pointed, the length of the middle rays being 

 one-third of that of the outer ones. Pectoral rather long, extending 

 to the twelfth scale of the lateral line. The ventral is inserted 

 immediately behind the vertical from the dorsal spine, and some- 

 what shorter than the pectoral. Scales with numerous radiating 

 striaj. Uniform greenish, shining silvery, with a darker stripe 

 along each scries of scales. Dorsal and caudal blackish.

Osseous dorsal ray very strong, strongly serrated. There are five 

 longitudinal series of scales between the lateral line and the ventral 

 fin. The height of the body is contained five times and one-third in 

 the total length (without caudal), the length of the head thrice and 

 one-half. The eye is a little nearer to the end of the snout than to 

 that of the praeoperculum, its diameter being one-half of the length 

 of the snout, and rather less than one-fifth of that of the head. 

 The dorsal fin occupies the middle between the base of the caudal 

 and the middle of the opercle, and commences immediately behind 

 the insertion of the ventrals. (Pet.)

Third dorsal spine not stronger than the other rays, flexible, and 

 not serrated. There are five (?) longitudinal series of scales between 

 the lateral line and the base of the ventral. Body rather elongate ; 

 snout moderately produced, with thick lips ; barbels somewhat 

 elongate. Eyes small. The orgin of the dorsal fin is midway 

 between the front margin of the orbit and the root of the middle 

 caudal rays f. Anal fin narrow and high ; caudal deeply forked, 

 the length of the middle rays being less than one-haK of that of the 

 outer ones. (Steind.)

t According to the description ; but in the figure it is midway between root 

 of the caudal and end of the snout, as in B. caninus.
