The anterior nasal valve is continued towards the median line 

 by a short fold, which, however, is far from reaching those of 

 the other side. The distance between the inner angles of the 

 nostrils is more than the length of a nostril. Snout produced.

 Gunth., Cat. Fishes VIII., p. 442. 



Anterior nasal valve not dilated laterally. Nostril very long,

 on the eyes or shoulders ; a median line of strong, compressed, 

 arched spines, placed far apart. The rostral ridges are arched 

 inwardly, and on their anterior part aro only separated by a
