X — I, 31; A. II, 7; scales 52 in lateral line, ^4 in transverse rows 

 above, 72 below, between insertion of dorsals and lateral line 9 or 10, 

 between lateral line and ventrals IS. Gill rakers 6+10 (and 3 or 4 

 rudiments) ; their length one-third diameter of eye. 



Body somewhat elongate and compressed, its width twice in depth; 

 dorsal profile evenly arched from snout to base of caudal peduncle, 

 ventrally somewhat less convex; length of abdomen from ventrals 

 to anus about 3 in length to base of caudal; distance from anus to 

 last vertebra 2^ in body. Head conical, dorsal profile little arched, 

 interorbital space only slightly convex from side to side; snout short, 

 blunt, broadly rounded, very convex dorsally, its tip vertical, or 

 slightly overhanging premaxillaries. Suborbitals somewhat broad, 

 flat. Lower jaw much shorter, included. Maxillary extending to 

 vertical from last fourth of eye. Cleft of mouth .oblique, anteriorly 

 below level of lower eye by nearly one-third diameter of eye. Teeth 

 in upper jaw in two bands; outer one row of larger, widely set, conical

teeth, stronger than remainder, but hardly canines; inner of a .band 

 of minute bristle-like teeth, 3 or 4 rows wide. In lower jaw an inner 

 single row of very small teeth, but somewhat larger than outer, 

 closely set, conical, moderately stout, with an outer band of bristlelike, 

 minute teeth, 4 or 5 rows wide at symphysis, but laterally only 2 or 3. 



Preopercle with rather firm, strong, bony teeth or spines a little 

 larger than inner row of mandibles, becoming larger and more widely 

 set at the angles than on upper and lower edges. Opercle with two 

 flat points, the lower somewhat larger. 



Dorsal spines weak, third and fourth highest, about twice in head, 

 first dorsal rays If in length of third spine and 2f in head, those 

 posterior not increasing much in height, the last four decreasing 

 rapidly, the last about equal to the diameter of the eye. Soft dorsal 

 base contained 2 J in body, that of spinous dorsal five times. Anal 

 higher than soft dorsal, first soft ray equal or somewhat longer than 



"The scales on this drawing were miscounted. See description.
