56 GOBIES OF THE PHILIPPINES 



This fish is common in estuaries and river mouths in central 

 and southern Japan, where it reaches a length of 300 milli- 

 meters. It also occurs in Korea and along the coast of northern 

 China, and has been recorded from Java. It is apparently very 

 rare in the Philippines. 



Genus 11. PALOA g. nov. 



Dorsal V, 1-10; anal I, 8; scales in longitudinal series 85 or 

 more; before first dorsal 55 or more; six rows of teeth in upper 

 jaw, those of outer row much enlarged, stout, conical; the 

 remaining teeth minute except the four central ones of the 

 innermost row, which are enlarged and strongly curved back- 

 ward; in lower jaw is an outer row of a few widely spaced, 

 enlarged conical teeth, followed by three rows of minute teeth. 



The robust body little elevated, laterally compressed, with 

 a large, wide, depressed head, full cheeks, oblique mouth, and 

 projecting chin; the eyes small, dorsolateral, the interorbital 

 space broad ; the vertical fins all low, the dorsals far apart, the 

 height of first dorsal less than half the depth of trunk; the 

 pectorals and ventrals narrow and short; the broad rounded 

 caudal much shorter than head; the entire body, except lips, 

 tip of snout, and ventral surface of head, covered with small 

 cycloid scales, which extend upon pectoral and caudal fins;

 first dorsal. 



The robust body subcylindrical anteriorly, the posterior part
