arched at first till opposite origin of soft dorsal, then straight to base 

 of caudal. Shields small, deepest about 10 in greatest depth of body. 



Spinous dorsal beginning well behind origin of pectoral, spines low, 

 fourth highest, fin rounded above, and depressible in a groove. Origin 

 of soft dorsal about midway between tip of mandible and base of caudal, 

 first ray highest, and anterior higher rays graduated down from it, 

 not forming a lobe. Last dorsal and anal rays hardly longer than those 

 preceding. Soft anal similar to soft dorsal, its origin a little nearer 

 base of caudal than front rim of orbit. Anal spines strong, short, 

 depressible in a slight groove, and first inserted about opposite origin 

 of soft dorsal. Belly in front of spinous anal with a short bony tren- 

 chant keel. Caudal small, forked, lobes pointed. Pectoral rather 

 broad and pointed. Ventral small, reaching nearly half way to soft 

 anal, and inserted a trifle in advance of origin of pectoral. Anus 

 well anterior, near tips of ventrals. 



Color when fresh in arrack with upper parts of body deep slaty-gray. 

 Sides and lower surface whitish, and more or less silvery. Spinous 

 dorsal black. Soft dorsal, caudal and anal dusky, other fins paler or 

 w^hitish. Opercle with a large blue-black blotch above, nearly as large 

 as eye. Iris yellowish. Peritoneum silvery.
