(J2 GOBIES OF THE PHILIPPINES 



groove between eyes; the interorbital space contained 3.6 to 4 

 times in head and is 1.75 times to a little more than twice an 

 eye diameter; the oblique mouth very wide, with strongly pro- 

 jecting lower jaw; the angle of maxillary beneath middle of 

 eye; the small villiform teeth in broad bands, with eight to ten 

 rows in each band ; the outer and inner rows a little larger than 

 the others; a short row of stouter teeth in front of lower jaw. 



The first dorsal very low, the second spine longest, and con- 

 tained twice in the depth of body; second dorsal low, its base 

 short, the posterior rays longest and about 1.7 in the depth; 

 anal farther back than second dorsal with a shorter base, but 

 higher, its longest rays about 1.4 in depth and extending farther 

 back than the dorsal rays when depressed ; the long, very broad, 

 rounded pectoral extends beyond the ventrals almost to or as 

 far as vent, and equals or almost equals the broad, gently rounded 

 caudal, which is 3.6 to 4 times in head and trunk; the caudal 

 peduncle very deep, its depth 1.5 to 1.66 times in its own length 

 and about 1.7 times in the greatest depth of trunk. The entire 

 body, except tip of snout, lips, and chin, covered with scales, 

 which extend upon pectoral and caudal fins ; those on sides from 

 head to tail are ctenoid; all others are cycloid; the scales on 

 cheeks and snout very small ; beginning on inner side of anterior 

 nostril a broad, naked furrow, marked by minute papillae and 

 separated from eye by a single row of small scales, extends back- 

 ward and curves around eye to a point opposite upper margin of 

 pupil; here it is joined by a similar but less noticeable furrow- 

 beginning below the forward margin of eye, and continues on 

 back along the side of head to a point above posterior angle of 

 operculum ; similar but much narrower grooves extend from the 

 furrow below eye diagonally backward upon cheek. 



The color in alcohol varies from reddish brown to blackish, 

 above and on sides, with yellowish to whitish belly; the sides 

 marked by narrow dark longitudinal lines; a broad blackish 

 crossband on upper half of spinous dorsal ; the margin is clear 

 and the lower half has narrow alternate bands of blackish and 

 white; all the other fins crossbarred with numerous alternate 

 dark and light spots or stripes ; base of pectoral yellowish with 

 two large dark brown spots, the markings resembling those in 

 the genus Butis. 



Here described from the type, No. 10594 Bureau of Science 

 collection, and three cotypes. The type is a male, 136 milli- 

 meters long, collected in March from Dumaguete River, Orien-
