Preorbital and preopercle with small flutings, edge of latter strongly 

 convex. 



■ Gill-opening carried forward below nostrils. Rakers 11+27, com- 

 pressed, slender, and longest about f length of longest filaments which 

 are about |- of orbit. Pseud obranchia? about half of eye. Isthmus 

 narrow, not trenchant. 



Scales small, narrowly imbricated, and cycloid. Head naked, except 

 cheek and upper posterior side above opercles. Spinous dorsal with a 

 low basal scaly sheath, but those of soft dorsal and anal well developed. 

 Base of caudal scaled, and that of pectoral naked. Straight portion 

 of lateral line beginning after elevated dorsal rays or at tip of depressed 

 pectoral. Scutes small, deepest 6^ in greatest depth of body. 



Spinous dorsal small, spines slender, pungent, depressible in a 

 groove, and third and fourth nearly equal. Origin of fin over first 

 fifth of length of pectoral, or nearly equal in space between tip of latter 

 and front rim of orbit. Soft dorsal beginning about over last third 

 of pectoral, or nearly midway between tip of mandible and base of 

 caudal. First few anterior rays elevated, and graduated down from 

 first and second developed rays which are longest. I^ast dorsal and 

 anal ray finlet-like and longer than preceding. Anal similar to soft 

 dorsal, its origin a little before tip of pectoral, or a little nearer base 

 of caudal than front rim of eye. Anal spines short, depressible in a 

 groove, posterior longer, and origin of fin almost opposite that of soft 

 dorsal. Caudal forked, lobes small and pointed, and no keels at their 

 bases. Pectoral long, falcate, and its origin nearly level with lower rim 

 of orbit. Ventral small, depressible in a groove, and about equal to 

 postocular region. Anus nearly midway between root of ventral and 

 origin of anal, or at tips of ventrals. 



Color when fresh in arrack grayish-silvery, somewhat slaty above, 

 and sides, together with lower surface, white. A large deep blue-black
