close together, prominent above the dorsal profile and situated in the 
first half of the head. Their diameter is 21/,—3 times the length of the 
head. The snout is rather obtuse and shorter than the eye. Anterior 
nostrils tubular. Sides of head and opercules naked. Crown of head 
and neck covered by rather large scales, partly imbedded in the skin 
and not easily visible. A pore between the eyes and behind each eye 
as well as on the hinder margin of the praeoperculum. Rictus some- 
what oblique. Jaws almost equal. Maxilla reaching under the front 
border of the eye. Lips thick. ‘Tongue truncated with rounded edges 
and the frontmargin slightly curved inwards. Outer row of teeth in both 
jaws enlarged, lancet-like. Scales ctenoid, those on the fore part of the 
body slightly smaller than the rest. First dorsal lower than the body 
in the female, in the male the middle rays are prolonged and exceed 
the height of the body. Second dorsal beginning above the vent, lower 
than the body. Anal beginning behind the second dorsal, lower than 
the body and with the hindermost rays the longest. Pectorals as long as 
the head, none of the rays free and silk like. Ventrals short, not reach- 
ing the vent, the rays prolonged beyond the membrane, giving the 
border of the fin a festooned appearance. Caudal rounded, !/, of the 
total length. 
Colour in spirits whitish, with 5 saddle like brown bands on the 
back. The first on the neck, the second under the first dorsal, the third 
and fourth under the second dorsal and the fifth on the tail. Ventrally 
they reach to the middle of the sides of the body, where they are partly 
confluent with a longitudinal row of somewhat darker brown blotches. 
A dark brown elongate patch under the eye and an indistinct stripe run- 
ning forward from the eye to the mouth. Brown patches on the sides 
and on the under surface of the head. Three or four small black spots 
above the origin of the pectoral. A black spot on the dorsal side and 
in the middle of tail at base of caudal. In the male there are some 
scattered black spots along the sides of the body and along the back 
similar to those above the pectoral. Two indistinct black bands on first 
dorsal. Rays of second dorsal and anal with black spots, forming dark 
bands on the fins. Pectorals, ventrals and anal dusky, darker in the male.

This species is allied to Ctenogobius hadropterus Jord. & Snyd. 
from Japan, from which it differs by having a shorter snout, a larger 
eye (age differences?) and by having the second dorsal placed more in 
advance, besides other small differences. It may easily be distinguished 
by the three or four black spots above the pectoral.
