286 GOBIES OF THE PHILIPPINES 



closely set scales, which become much smaller before first dorsal, 

 and extend forward above opercles as far as above middle of 

 preopercles; the scales and fins more or less obscured by a 

 heavy coat of mucus ; the second and third spines of first dorsal 

 longest, 1.8 to 2 times in head; the second dorsal and anal alike 

 in shape, approximately equal to first dorsal in height, not touch- 

 ing base of caudal when depressed; the caudal peduncle broad, 

 short, its depth equal to or exceeding its length and 2.1 times 

 in head ; the obtusely rounded caudal 3.78 to 4 times in length ; 

 the round pointed pectoral equals or slightly exceeds caudal ; the 

 rounded ventrals as broad as long, about 1.7 to 1.8 times in head; 

 the anal papilla large, pointed, triangular. 



The color in alcohol brown or dusky brown, the fins all blackish 

 or the first dorsal pale at base, the first spine with black spots, 

 the rest of the fin blackish ; the second dorsal may be pale ante- 

 riorly along base; the pectoral always has a broad yellowish 

 or whitish crossbar near base, and is narrowly margined with 

 the same color. 



Here described from six specimens, 64 to 85 millimeters in 

 length, collected at Fu-chow, Fukien Province, China, by Light. 

 I also have seven specimens, 50 to 80 millimeters long, collected 

 on the mainland near Amoy, by Light, May 4, 1923; a female, 

 65 millimeters long, was ready to spawn when taken. 



This species is known only along the China coast from Hong- 

 kong northward. It may well occur in the Batan Islands or 

 on the Ilocano coast of Luzon.
