 distant from snout and adipose; adipose well-developed; caudal deeply forked, 

 its lobes equal, about 3.5 in the length; anal obliquely truncate, its highest rays 

 not reaching base of last ray; ventrals not reaching anal by one or two scales; their 

 origin near middle of the length; pectorals reaching ventrals.
