5 If) SEALK. 



Body is oblong, compressed, rather detp, greatest depth at origin of 

 Yentrals. The upper outline is an even curve to the anterior margin 

 of eye, it is slightly more convex from this point, the practically 

 straight snout extends down to the protractile upper lip, at an angle 

 slightly greater than 45°. Lower outline from anal to tip of snout 

 forming a low even curve, the lower jaw being but slightly oblique. The 

 depth of caudal peduncle is 1.50 in its length, its median width is 3 in 

 its length, while its length is 2 in head. Greatest depth of head equals 

 its length, its greatest width 2 in length; interorbital space slightly 

 convex. Outline of snout almost straight, excluding the protractile upper 

 jaw; width of upper lip at symphysis 2.50 in pupil; maxillary ends 

 slightly posterior to anterior nostril; the mandible ends on a line with 

 anterior margin of eye. Eye is large, I.-jO in snout. Preorbital 2.50 in 

 head, jaws equal. Teeth of upper jaw consisting on each side of three 

 large molars, two of which have cusps, five conical teeth, and two large 

 curved anterior canine^;, also a patch of minute teeth in anterior of jaw, 

 behind the canines. Lower jaw on eacli side with four large molars, 

 three of which are biscuspid, fi^'e conical teeth, two canines, and a patch 

 of minute teeth just inside the curved anterior canines. Xo teeth on 

 vomer or palatines, opercle ends in a fiat spine and has a rather broad 

 yellow membranous margin. 



Gill openings end on a line with middle of eye, the gill rakers are 

 short, thick ami blunt, four on lower limb, the longest less than one- 

 fourth of pupil. Pseudobranchia present. 



Body entirely co\ered with large smooth scales which are slightly 

 denticulate on margins ; head naked except on opercles and a small patch 

 of scales behind and above eye. The spinous dorsal when collapsed is 

 fully hidden in scaly sheath. Fins not scaled exee]3t base of pectorals 

 and caudal. Origin of dorsal is directly above axil of pectoral, its fourth 

 to fifth spines are longest, 2.75 in head. Longest dorsal ray 2.25 in head. 

 Origin of anal is over second dorsal ray, its third spine is the longest, 

 3.25 in head, the second spine is strongest. Longest anal ray 2.75 in 

 head. Origin of ventrals midway hetweeii tiji of snout and posterior 

 axil of anal. Tips of venlj-als reach to anal pore. Tips of pectorals 

 extend to base of anal. C'audals deeply emarginate, its longest lobe 

 1.20 in head, its shortest lay 2..')0. 



(Jolor in life yellow, with slight wash of grajisli, fins immaculate, 

 except ventrals which have dusky tips and caudal which is washed with 

 yellow. 



('ol(;r in alcohol whitish, slightly grayish drab above; the middle of 

 each row of scales darker, making 4 or 5 narrow longitudinal lines 

 above the lateral line, these rows follow the curvature of the back. A 

 large rather indistinct oblong dusky blotch between the pectoral and 

 lateral line, base and upper axil of pectoral grayish. The fins are white.
