206 GOBIES OP THE PHILIPPINES 



males with maxillaries produced backward; a dark spot or bar 

 on base of pectoral; the first dorsal spine alternately clear and 

 black-spotted ; the membrane of first and second dorsal and anal 

 dusky with minute dark specks ; the caudal faintly barred with 

 dusky bands ; the ventrals blackish with paler or white margins. 



In fresh specimens, the lines and vermiculations before the 

 dorsal and the spots and marks on the dorsal part of the body 

 were dark red; the eye spot or bar on the iris was of the same 

 color; the band from the eye to the underside of the head was 

 black; the dorsals were crossbarred by rows of brown spots; 

 at least the upper half of the caudal was crossed by rows of 

 small dark spots ; the pectorals were golden ; the anal was golden 

 with a broad dusky margin. 



Here described from a number of specimens, from 32 to 50 

 millimeters long. They are part of a lot of fifty-two specimens, 

 ranging down to a length of 18 millimeters, collected by me 

 from Abra River, Cauayan, Ilocos Sur Province. I have also 

 examined the generic type at Stanford University, and the 

 following specimens in the Bureau of Science collection : 



Vigan, Ilocos Sur Province, 13. Bigaa and Arimbay Rivers, 

 Agno River, Dagupan, Panga- Albay Province, 35. 



sinan Province, 10. Libog River, Albay Province, 

 Baliuag, Bulacan Province, 1. 18. 



Subic, Zambales Province, 1. Puerto Galera, Mindoro, 1. 



Lake Taal, Batangas Province, San Jose, Antique Province, 5. 



56. Capiz, Capiz Province, 13. 



Pansipit River, Batangas Prov- Molo, Iloilo Province, 9. 



ince, 1. Villa, Iloilo Province, 1. 



The largest specimens of this variable species are 66 milli- 

 meters long. I place here also a specimen, 52 millimeters long, 

 collected by Alvin Scale at Caldera Bay, Mindanao, in 1908. 

 It is in bad condition and differs from the others in having 

 small circular black spots scattered thinly over the entire head, 

 including the jaws, and the upper half of the body back to the 

 tail; other color markings have entirely disappeared, with the 

 exception of the conspicuous brown bar from the eye to the 

 lower margin of the preopercle. 



This species was listed by Jordan and Richardson from Aparri, 

 at the northern end of Luzon, and by Smith and Seale from 

 Cotabato, Mindanao. The Rhinogobius ocyurns of Jordan and 

 Seale is probably this species. 



This fish occurs from the coasts of India to the Philippines.
