Ig4 GOBIES OF THE PHILIPPINES 



This species has a strong resemblance to Gobius ornatus, 

 with which it would be readily confused if it were not for the 

 pectorals. 



Here described from two specimens, 31 and 38 millimeters 

 long, collected at the barrio of Nalvo, Luna, La Union Province, 

 Luzon. It has been previously known solely from the type 

 specimens collected at Caldera Bay, a few kilometers north of 

 Zamboanga, Mindanao.
