282 GOBIES OF THE PHILIPPINES 



each jaw, those of outer row tricuspid, and set alternately so 

 that they can almost be said to form two rows; the inner row 

 is some distance behind, of simple, sharp, small but stout teeth; 

 the head entirely naked; the body covered with ctenoid scales 

 which are smaller above pectoral base and extend forward of 

 first dorsal, greatly reduced in size as far as above posterior 

 margin of preopercle; the first dorsal low, the central spines 

 longest, not reaching second when depressed, 2.5 to 2.9 times in 

 head and twice to 1.66 times in depth; the second dorsal and anal 

 alike in shape and height, the anal shorter than dorsal, not 

 touching base of caudal when depressed, higher than first dorsal, 

 2 to 2.33 times in head, and 1.4 to 1.7 times in depth; the depth 

 of caudal peduncle is 1.33 to 1.6 times in its own length and varies 

 from a little more than 10 to 15 per cent of total length; the 

 caudal of moderate size, rounded, the accessory spines extending 

 well up on caudal peduncle, 1.3 to 1.5 times in head and 4.1 to 4.5 

 times in length; the broad, round-pointed pectoral equals or is 

 greater than depth, and is a trifle longer than caudal, which 

 equals or is slightly less than depth ; the ventrals nearly as broad 

 as long, semicircular, with a fleshy frenum, 1.6 to 1.85 times in 

 head, falling far short of anus; the anal papilla thin, slender, 

 pointed in males; in females it is stout, subcylindrical, with a 

 bifid point. 



The color in alcohol yellowish brown or olive brown, with 

 vaguely defined, blackish vertical or diagonal crossbars as fol- 

 lows: A short bar on. top of head a little behind eyes, a larger 

 one a little back of this, and a third one above pectorals ; a fourth 

 bar passes under posterior half of first dorsal ; the fifth crosses 

 under middle of second dorsal, the sixth just behind it, the last 

 two inclined diagonally forward; there is a dark circular spot 

 below eye and a dark blotch from eye diagonally back upon 

 cheek; a large dark spot on base of pectoral and one on upper 

 and one on lower pa.rt of caudal base ; the first dorsal crossed by 

 one or two broad diagonal blackish crossbands or the whole fin 

 may be blackish except basal part of first three spines ; in some 

 specimens the anterior third of second dorsal is whitish with 

 longitudinal rows of dusky spots on membrane, and upper mar- 

 gin blackish; the rest of the fin blackish; in others the second 

 dorsal is barred alternately with whitish and blackish bands, 

 the membranes everywhere specked with dark dots; the caudal 

 obscurely barred with five or six rows of dark spots ; the pecto- 

 rals crossbarred by numerous rows of blackish spots; the ven-
