front margin of the eye ; mandible with a symphysial hook. Lateral 

 line descending in a curve towards the ventrals. Dorsal fin nearly 

 entirely in advance of the anal. Pectoral fin longer than the head, 

 nearly extending to the root of the ventral. Pharyngeal teeth

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 line 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 reachiug the root of the ventral. Thorax 

 compressed into a sharp edge supported by the dilated 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. GiU-rakers rudimentary. The middle of the hinder edge of

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

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

 latter 150-175.
