dorsal in height, the posterior rays of both somewhat elongate 

 and angulate, never reaching caudal when depressed; the depth 

 of caudal peduncle 2.3 to 2.5 times in head and 1.5 to 2 times 

 in its own length, which equals depth of body; the broadly 

 rounded caudal 3.5 to 3.75 in length and 0.8 to 0.9 as long as 

 head; the pectoral a little shorter than caudal, 0.7 to 0.8 of 

 head; the ventrals are typical of the genus, very short and 

 rounded, twice or more than twice in head and reaching less 

 than halfway to anus; the anal papilla small and triangular 

 in males, much broader and blunter in females.

 minute, dark brown spots, which may extend upon pectoral 

 base ; ,all the fins more or less brown to blackish, the ventrals 

 palest, with traces on second dorsal of cross rows of darker 

 spots; the tips of the two anterior spines of first dorsal and 

 the tips of second dorsal rays usually silvery white; the tip of 

 caudal white. 



Here described from fourteen specimens, 33 to 53 millimeters 

 in length, from Irid River, Santa Ines, Rizal Province, and 

 twenty-two cotypes, 30 to 60 millimeters long, from Banaban 

 River, Angat, Bulacan Province. Two of them are females, 

 40 millimeters long, ready to spawn; their eggs are few and 

 very large, 1.75 millimeters in diameter. 



The Banaban River specimens have the ground color pale 

 yellowish or yellowish gray, with five broad, blackish, dorsal 

 crossbands which divide on the sides and form a series of 

 broad lateral bands or spots more or less united along the mid- 

 dle of the sides; the posterior bands may be divided so as to 

 form a series of zigzag bands, with the ground color forming 

 pale or golden spots dorsally and laterally between them ; there 

 is a black crossband at the base of the caudal with a trans- 

 verse black spot behind it; the sides of the head are sprinkled 

 with tiny, dark brown specks, which may extend upon the pec- 

 toral; the first dorsal is blackish, with the upper anterior part 

 silvery white; the other fins are more or less golden, with 

 blackish rays, or the membranes may be partly violet-red, and 

 with a white or golden margin; the second dorsal is obscurely 

 crossbarred with faint, dark brown dots; the pupils are white.
