 length of the head (without subopercle) ; each side of each jaw with about twelve to 

 fifteen tricuspid teeth in a single series. No teeth on the maxillary; suborbitals 

 leaving about half the cheek naked. 



Origin of dorsal equidistant from snout and tip of adipose or upper caudal 

 lobe, the rays nearly equal in height in the female, the eighth to the twelfth of the 

 male prolonged, reaching the caudal; anal rounded in the female, lanceolate in the 

 male, the middle rays reaching beyond basal fifth of the caudal; ventrals reaching 

 more than half-way to end of anal; pectorals half-way to middle of ventrals. 



Sides uniformly dotted ; a large spot a little below the middle at the end of the 

 caudal peduncle; last rays and sometimes base of the dorsal and last rays of the 

 anal hyaline, the rest of these fins uniformly dark with irregular bars or spots; corre- 

 sponding parts of dorsal and anal in male with conspicuous semi-hyaline oval 

 spots surrounded by much darker.
