Description: Dorsal fin with I,5,i, or I,6 rays; Anal fin with iv,8, iv,9, iv,9,i, iv,10 or iv,11,i rays; pectoral fin with  I,7,i, I,8 or I,8,i rays; pelvic fin with i,5 rays. Colour: Darkish brown above and sides, dirty yellow below; head, sides and fins mottled with dark spots; fins excepting caudal and adipose with spotted bands. Habitat: Lives mainly in hill streams.
