Scales large and thin. The height of the body is contained five 

 times and one-half in the total length (with the caudal), the length 

 of the head six times and one -half. Eye large, rather close to the 

 end of the pointed snout ; lower jaw but slightly projecting beyond 

 the upper. Dorsal fin above the anterior anal rays. Pectorals not 

 extending on to the ventrals, one-fifth of the total length. Curva- 

 ture of the lateral line inconspicuous.

The height of the body is nearly equal to the length of the head, 

 which is one-fifth of the total (without caudal). Snout longer than 

 the eye, much compressed ; mouth very oblique and wide, the 

 maxillary extending beyond the front margin of the orbit ; man- 

 dible with the symphysial hook much developed. Suborbital ring 

 narrow. The lateral Une descends gradually in a straight line below 

 the middle of the side. Origin of the dorsal fin opposite to that of 

 the anal. Pectoral fin very long, two-sevenths of the total length 

 (without caudal), not reaching the root of the ventral. Thorax 

 compressed into a sharp edge supported by the dUated bones of the 

 forearm. Caudal fin comparatively short, forked ; a blackish blotch 

 at its base. 



Pharyngeal bones very narrow, teeth small, uncinate 5 . 4 — 4 . 4 

 or 5. Gill-rakers rudimentary. The middle of the hinder edge of

* The scales are very irregularly arranged, which accotmts for the difference 

 of Valenciennes's and Eleeker's statements, the former counting L. lat. 90, the 

 latter 150-175.
