gg GOBIES OF THE PHILIPPINES 



gravel, or mud, but not habitually swimming freely in the open 

 waters of sea, river, or lake. Some species live in the interstices 

 of coral ; others hide under stones at or near tide mark, or dwell 

 in tide pools. So far as I am aware, none burrow in the mud 

 as do various species of the eel-like Gobioididae. 



Luzon seems to be particularly rich in genera and species of 

 small lake and brook gobies, each geographical unit of the island 

 having species apparently limited to that particular watershed or 

 fluvial system. When the streams of all the large islands have 

 been as well worked as have those of parts of Luzon and Panay, 

 we may confidently expect a very large increase in the number 

 of Philippine species of Gobiidse known. However, no great in- 

 crease is to be expected in Mindanao, since over a large part of 

 the island Cyprinidse take the place of Gobiidae as brook dwellers. 



There are described here forty-eight genera and one hundred 

 twenty-seven species of Gobiidae, of which ten genera and fifty- 

 four species are new. This large number is probably less than 

 three-fourths of the species actually occurring in the Philippines. 



Gobiidas from the Philippines and the China Sea.
