VAIMOSA 153 



The color in alcohol whitish with a wide, vaguely limited, 

 black band from shoulder to base of caudal, and two similar 

 but narrow and much fainter black bands above, between it and 

 the dorsal fins, or all the scales above the middle band may be 

 lightly black margined, leaving the middle of each scale as a 

 whitish spot; the opercles and preopercles reticulated or diag- 

 onally marked by a few broad brown bands composed of minute 

 dots; a black blotch on upper part of. posterior or central 

 part of first dorsal, the remainder of fin clear except for a 

 black spot or two on the first spine ; three or four crossbars of 

 blackish brown dots on second dorsal and about five transverse 

 or diagonal blackish transverse bars on caudal; the anal and 

 ventrals blackish or dusky, the pectorals clear. 



Here described from twenty-one specimens, 16 to 26 milli- 

 meters long, from Sapanga Creek, Angat, Bulacan Province, 

 Luzon. The larger specimens are adults, some of them females 

 ready to spawn at the date of their collection, September 24, 

 1925. I also collected four specimens, 15 to 22 millimeters in 

 length, from Gumay River, Pampanga Province, the coloration 

 of which is much darker. This little fish unquestionably occurs 

 in gravelly brooks throughout the whole region tributary to the- 

 northern part of Manila Bay. 



I refer here a specimen, 25 millimeters long, collected by me 

 in the Tagmatay, a brook on the Allen ranch near Cagayan, 

 Misamis, Mindanao. The specimen is brown with a well-defined, 

 very dark brown band on the side from the axil of the pectoral 

 to the caudal. 



Sapanga or sapa ng a is Tagalog for "the A brook," the local 

 name for the streamlet where the type specimens were collected.
