horizontal, pointing inward, enlarged, the posterior ones very 

 much so, the inner rows minute ; the scales on forward portion 

 of body very small, becoming much larger posteriorly; they 

 extend before first dorsal as far as front margin of the very 

 narrow opercle ; the first dorsal high, the middle spines longest, 

 0.9 of the length of head ; the sixth spine separated by a con- 

 siderable space from fifth; Scale was in error in stating it to 

 have seven spines and the figure is incorrect in showing the first 

 spine as longest; there is a projecting filament of skin behind 

 sixth spine but no additional spine; the second dorsal and 

 anal sharply angulate posteriorly, the last or next to the last 

 ray longest, 1.5 times in head, or f its length; the caudal pointed, 

 3.25 times in the length and | longer than head; the rather 

 narrow pointed pectoral i as long as head; the ventrals have 

 a wide frenum forming a very deep cup, their length equal to 

 head, the narrow pointed tip reaching the small, conical anal 

 papilla. 



The color, according to Seale, was light brown, with a wide, 

 dark brown saddle over back under first dorsal and extending 

 downward on sides and belly; a dark brown area along middle 

 of sides to base of caudal; a brownish area behind eyes and 

 one below them; about fifteen blue spots on sides of head and 

 base of pectoral ; the first dorsal and anal dark purplish, lighter 

 basally, and approaching black above; the ventrals dark pur- 

 plish; the second dorsal blackish basally and along margin, the 

 rest of the fin with three longitudinal rows of white spots and 

 two longitudinal lines of blackish spots; the caudal and pec- 

 torals uniform brown. After fifteen years in alcohol the mark- 

 ings have changed little; the second dorsal, however, is now 

 practically all brown and the spots on the sides of the head are 

 blackish brown. 



The type and only specimen is a male, 80 millimeters long, 

 collected by Seale in Hongkong.

 The body elongate, the sides strongly compressed, the head 

 large, blunt, broad, the body deepest at origin of ventrals; the 

 mouth of medium size, oblique, with strongly projecting chin; 

 the upper jaw has an outer row of enlarged fixed teeth, some 

 of those in front caninelike, and four rows of very small de-
