 7-90 or 91-28. Vent situated under the twelfth ray of second dorsal, 

 and e(]uidistant from tip of snout and end of second dorsal; distance of 

 dorsal fin from snout equal to twice length of mandible; third ray of first 

 dorsal extremely elongate, extending to a point (thirty-third ray of sec- 

 ond dorsal) f of distance from snout to tip of caiulal, its length more than 

 twice that of head, and more than 4 times as long as the rays immediately 

 preceding and following it; anal fin inserted immediately behind vent, its 

 distame from root of ventrals eijual to that of dorsal from snout; as in 

 other species of the genus, ventral of 3 rays, the first 2 much prolonged, the 

 first contained 3 times in length of body, the second almost 3 times as loug

 caudal, the third shorter than diameter of orbit; pectoral 4 times as long 

 as operculum. Scales large and thin, easily wriukling with the folding 

 of the thick, loose skin, particularly in the median line of sides of body.
