The fish is 7 cm. long and has 18 narrow dark cross bands, whicli 

 extend to the median line of the back and are deficient on the lower 

 part of the body; 7 of the bands are predorsal, 3 subdorsal, and 8 

 postdorsal, in addition to a narrow, sharply defined, vertical black 

 stripe at the base of the caudal fin. A black bar extends from the 

 axil of the pectoral fin to a black blotch at the beginning of the lateral 

 line; there is a diffuse brownish area on the upper part of the opercle; 

 the whole upper surface of the head is covered with rounded black 

 spots; a brown stripe extends under eye to angle of mouth; the pale 

 yellow dorsal fin has a jet-black spot at its base anteriorly and several 

 transverse rows of dark spots on the dorsal rays; and the greenish- 

 yellow caudal fin has five irregular transverse rows of brown spots. 

 The barbels are long, all reaching to or beyond the eye; the eyes, in- 

 visible from below, are much nearer to tip of snout than to the gill 

 opening; the anterior nostril is in a tube with a posterior flap, which 

 nearly reaches eye; the lateral line terminated in advance of the 

 anal fin.

The status of this species as a Thai fish is somewhat uncertain. De- 

 scribed by Day (1878) from Darjeeling and Assam, India, the species 

 was lost sight of until Vinciguerra reported it from Burma near the 

 Thai border in 1890. 



In a mountain brook at Pang Meton, on Doi Nangka, Northern Thai- 

 land, 20 specimens, 4.3 to 8.4 cm. long, were collected April 28, 1931.
