Length of head 4 to 4f- ; depth of body 4 to 4^ in 

 the total length ; width oi: head If to 2 of the convex 

 interorbital region 3f to 3f ; diameter of eye 3/y to 

 4 in the length of the head ; snout obtuse, as long 

 as or a little longer than the eye ; maxillary as loug as 

 or a little shorter than the diameter of the eye, reaching to 

 or nearly to the vertical from its anterior margin ; distal end 

 of the preorbital rounded and oblique, not so wide as the 

 pupil ; posterior half of the lower and the hinder borders 

 denticulated ; 27 to 29 gill-rakers on the lower branch of 

 the anterior arch ; body ralher elongated, the dorsal and 

 ventral profiles equally and slightly convex. The origin of 

 the spinous dorsal is midway, or a little in advance of 

 midway, between the base of the caudal and the extremity of 

 the snout ; the spines are feeble, the first straight and but 

 little longer than the second, its length If to 2 in that 

 of the head ; the third spine is intermediate in length 

 between the second and the fourth, which is 2 to 2^ in 

 the length of the first ; the space between the origins of the 

 dorsal fins is as long as or a little longer than the head ; the 

 anterior rays are as long as the first spine, and the outer 

 border of the soft dorsal is moderately emargiuate, the last 

 ray being slightly produced ; the anal originates well in 

 advance of and does not extend quite so far back as the 

 second dorsal, its base being as long as or a little shorter than 

 its distance from the caudal ; the anterior rays are slightly 

 longer than those of the dorsal, and when laid back extend to 

 or a little beyond the base of the last ray, which is moderately 

 produced, the outer border of the fin being deeply emarginate ; 

 ventral inserted beneath or a little behind the middle of the 

 pectoral, its length If to l^ in that of the head, and 

 2i to 2f in the distance between its origin and the anal; 

 the middle ray the longest ; third and fourth pectoral rays 

 the longest, not extending to beneath the origin of the 

 spinous dorsal, 1^ to IJ in the length of the head ; 

 caudal peduncle long and slender, its least depth 2f to 

 2f in the depth of the body, and If to 2 in its length. 

 The elongated scale in the axil of the ventral is small ; no 

 pointed scale at the base of the spinous dorsal ; some small 

 scales between the anterior rays of the anal fin.
