Diagnosis of Species. (Br. vii.: D. 7-8/42-44; A. 15-18 (+ 3)* / 15-20 ; L. 

 lat. 87—95. Vert. 5 If). — Barbel slender, black, much shorter than eye. Both 

 anal fins below posterior two-thirds of second dorsal, sub-continuous, the apparent 

 interspace occupied by three minute rays. Anterior ray of first dorsal produced 

 into a short filament. Margin of second dorsal indented. Two outer rays of 

 pelvic fin filamentous, the second ray the longer, reaching beyond anus which is 

 situated slightly anterior to the median point. Lateral line slightly curved at 

 anterior region. Scales large cycloidal, longer than broad. 



Length of head about 4^ to 4f in length of fish without caudal. Total length 

 of fish fully 5^ times extreme depth. Diameter of eye, 3—31 in length of head, 

 greater than snout. 



Interorbital space j in length of head in adults. Snout broad, obtuse. Upper 

 jaw the longer. Opening of mouth extending to beneath centre of eye. Teeth of 

 both jaws cardiform, in bands, widest anteriorly. A toothless interspace at anterior 



* The three minute rays, included in the bracket, may be omitted from the formula, as appears to 

 have been done by previous writers. They appear to us to be connected with the first anal fin, if specially 

 with either.
