PLATE 16, FIG. 3 



Dorsal VI, 1-10 or 11; anal I, 9 or 10; there are 38 to 42 

 scales in a longitudinal series and 13 or 14 in a transverse series. 



The body elongate, plump, laterally compressed, the depth in 

 sexually mature males about 5 times in length, in ripe females 

 4.3 to 4.9 times; the head 4 to 4.3 in length; the very short, 

 convex, blunt snout from 3f to 4 times in head; the eyes high 

 up, dorsolateral, their gaze almost as much upward as sideways, 

 equal to snout; the interorbital space very narrow, 3 to 6 times 

 in eye; the small mouth oblique, the jaws equal, the posterior 

 angle of maxillary under anterior third of eye or anterior part 

 of pupil ; the minute teeth in two rows above and two or three 

 in lower jaw, with a pair of small, outward-curving posterior 

 canines in outer row ; the tongue very slightly notched ; the head 

 entirely naked; the trunk covered with ctenoid scales, largest 

 posteriorly, except on breast, pectoral bases, and nape, where 

 they are very small and cycloid ; the scales on nape do not extend 

 forward beyond opercles, about fifteen or sixteen rows in front 

 of first dorsal ; a pore on the anterior and one on the posterior 

 part of interorbital space, four in the supraopercular groove 

 running from eye to pectoral base, and three on the posterior 

 margin of preopercle; the dorsals well separated, their height 

 in general the same and a little more than f the depth of body ; 

 the second dorsal spine may have the tip elongated and thread- 

 like in males, when it may be longer than the head and extend 

 to third dorsal ray when depressed; the posterior ray of second 

 dorsal longest, reaching base of caudal when depressed; the 

 anal similar in shape, but with a shorter base, its height equal 

 to or seven-eighths that of second dorsal, but its posterior rays 

 never reaching caudal; the pectorals and ventrals pointed, of 

 equal length or the ventrals a little shorter, equal to or a little 

 shorter than head; the depth of caudal peduncle 0.6 of its own 

 length and If times in head; the caudal pointed, 2.7 to 2.8 

 times in length in males ; in females it may be as long or shorter, 

 to 3.3 times in length; the anal papilla small, slender, and 

 pointed in males, stout, rounded, and short in females. 



The color in alcohol pale whitish, with two black longitudinal 

 bands on sides ; the first begins behind eye and extends back to 

 upper origin of caudal ; the other and wider band begins in axil 

 of pectoral and ends at middle of base of caudal ; on it are six
