for half their length, longer than head and reaching far along 

 second dorsal when depressed; the second dorsal elongate, its 

 base extending almost to caudal, low, its height 0.75 the depth of 

 body, and twice or nearly twice in head, the posterior rays 

 reaching far out on caudal when depressed ; the low anal likewise 

 has a very long base, the posterior rays a little the longer, 2.5 

 to 3 times in depth, 3.75 to 4 times in head; the caudal peduncle 

 very short, its depth about 2.8 to 3 times in head, about twice 

 in depth, and twice its own length; the caudal narrow, sharply 

 rounded to acute, equal to or a little shorter than head, the lower 

 margin obliquely truncate: the pectoral acutely pointed, its 

 muscular scaled base nearly half its length, 1.4 to 1.8 times in 

 head ; the short ventrals a third or half as long as head and about 

 2.5 times in the distance to anus; the anal papilla small, 

 elongate-triangular, pointed. 



The color in alcohol bluish gray or slate to brown, paler 

 beneath; the first dorsal blue slate or bluish, with many white 

 spots, which may form short horizontal lines ; the second dorsal 

 has the same ground color, with from four to seven longitudinal 

 rows of elongate white spots; the caudal with elongate, oval, or 

 round white spots between the rays; the other fins pale, un- 

 spotted. 



Here described from three specimens, 96 to 115 millimeters 

 in length, collected by Light at Amoy, China. The Bureau of 

 Science collection also contains five specimens, a little smaller, 

 collected by Scale at Hongkong. 



This species ranges from Burma to Japan. It may well occur 

 along the Ilocano coast of Luzon.

Scartelaos SWAINSON, Nat. Hist. Fishes 2 (1839) 279. 



Dorsal V or VI, 1-24 to 26; anal I, 23 to 25. 



The anterior teeth of upper jaw unequal, awl-shaped canines, 

 curved inward; in lower jaw the teeth are horizontal, simple, 

 medium in size, acute; the scales small to microscopic and 

 rudimentary, few, not conspicuous or else absent on head and 

 forward part of trunk ; the body elongate, the dorsals far apart, 

 the spinous dorsal more than 3 times as high as the length of 

 its base, the base of second dorsal more than 5 times the length 

 of that of first; the caudal long, pointed, its lower margin 

 obliquely truncated ; the muscular base of pectorals shorter and 

 less developed than in the other Philippine genera ; the ventrals
