 body and cheek firmly scaled: caudal peduncle narrow and flat, its width greater than depth: snout flat, its 

 width at angle of mouth 1..50 in length; maxillary short, 3.5() in head, its distal end scarcely reaching second 

 nostril; lower jaw projecting: a single long saber-like spine at angle of preopercle, this spine considerably 

 longer than diameter of eye, being 4 in head: no spine directed fom'ard: 3 very small spines on bon}* stay of 

 cheek, one on a line with middle of pupil and another mth posterior margin of e_ye, the third with posterior

pupil; minute bands of teeth on jaws, vomer, and palatines; tongue broad, roimded, spatulate, free; gillrakers 

 rather sharp and slim, the longest equahng one-half of eye, IS on lower limb; first doi'sal spine small, somewhat 

 separated from second, which is the longest and strongest spine, being 2.60 in head; first soft doi'sal ray 2.10; 

 seventh tu eleventh rays rather wide and separated from other rays except at base, origin of soft dorsal slightly 

 nearer base of caudal than tip of snout; origin of anal slightly in advance of soft dorsal, its base slightly greater 

 in length than base of soft dorsal; pectorals 2.10 in head; ventrals 2, their spine strong, their origin below 

 middle of pectoral; caudal slightly forked, the upper lobe much the larger and longer, usually prolonged into 

 a filament which is about equal in length to remaining portion of fin. 



Color in spirits yellowish, with wash of brownish above; an indistinct broken longitudinal brown band 

 along side; a dusky splotch on anterior of opercle; spinous dorsal with 3 rows of dark spots; soft dorsal and 

 upper lobe of caudal with spots; lower lobe of caudal with spots larger, about 3 in number, the posterior 

 one being a rather large blotch; pectorals and ventrals yellow.
