H2 GOBIES OF THE PHILIPPINES 



I have been unable to get a copy of Bleeker's diagnosis of 

 this genus. 



This group includes small dull-colored fishes of tide pools, 

 rocky, shallow, coastal waters, and river mouths. One of the 

 species is the most widely diffused of all gobies. 



Key to the Philippine species of Bathygobius.

 a 2 . No black spots on body as above. 



b 1 . Sides with longitudinal rows of white spots; four or five dark brown 

 dorsal crossbands, six or seven dark brown lateral spots B. fuscus. 

 5 2 . No white spots on sides.

 tudinal series, 13 in a transverse series, and about 16 before the 

 first dorsal. 



The wedge-shaped body strongly compressed posteriorly, with 

 very broad head, the depth 4.5 in the length; the head 3 times 

 in length, its breadth equal to depth of body, and 0.2 more than 

 its own depth; the broad rounded snout 3.6 times in head; 

 the mouth terminal, slightly oblique, jaws equal, posterior angle 

 of maxillary beneath pupil; the outer row of teeth in upper 

 jaw enlarged, with three inner rows of very small teeth; in 

 lower jaw an outer row of larger teeth and two inner rows of 

 minute teeth ; the tongue notched ; the eyes very high up, latero- 

 dorsal in position, equal to snout, and in forward half of head; 

 the interorbital space narrow, 2.5 times in eye ; the body covered 

 with small scales a little larger posteriorly; those on nape ex- 

 tend to eyes and are very small; a few small scales on upper 

 margin of opercle ; the dorsals well separated, the height of first 

 equal to f the depth of body ; the second dorsal and anal a little 

 higher, 0.75 to of depth, reaching about halfway to caudal 

 when depressed; the caudal equal to the pointed pectoral in 

 length, about more than the depth and I of head; the pec- 

 toral reaches to a point beyond anus but not to anal fin; the 

 ventrals rather thin, broad, and short, extending halfway or
