The height of the body is one-fourth of the total length (without 

 caudal), the length of the head two-ninths or one-fifth. Snout as 

 long as the eye, the diameter of which is two-sevenths of the length 

 of the head. Suborbital ring very narrow ; the maxillary extends 

 to the front margin of the eye. The lateral line descends in a wide 

 arch to above the ventral fin. Origin of the dorsal fin scarcely in 

 advance of that of the anal. Pectoral fin very long, much longer 

 than the head, extending beyond the root of the ventral. Thorax 

 compressed into a sharpish edge supported by the dilated bones of 

 the forearm. Each caudal lobe with a blacldsh longitudinal band.

The height of the body is one-third of the total length (without 

 caudal), the length of the head one-fifth. Snout as long as the eye, 

 the diameter of which is two-sevenths of the length of the head. 

 Mouth very oblique, rather narrow, the maxillary not extending to 

 the front margin of the orbit. Mandible with the symphysis scarcely 

 hooked. Suborbital ring narrow. The scales of the nape advance 

 nearly to above the front margin of the orbit. Lateral line descend- 

 ing in a gentle curve towards the ventral fin. Origin of the dorsal 

 fin opposite to that of the anal. Pectoral fin exceedingly long, one- 

 third of the entire length of the fish, extending to the anal. Thorax 

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

 forearm. Ventral small, inserted somewhat above the abdominal 

 profile. 



Pharyngeal teeth 5.4. 2—2 .4.5. The middle of the hind 

 margin of the gill-membrane is opposite to the angle of the pree- 

 operculum.
