Specimens collected by Deignan in the Menam Mao agree fairly well 

 with the descriptions and figures of this species; they are 5.6 and 5.9 

 cm. long. 



NOEMACHEILUS SPILOTUS Fowler 



Nemacheilus spilotus Fowler, 1934a, p. 105, fig. 57 (Chiengmai, Chiengdao, 

 Metang, Khun Tan). 



Known from numerous specimens, 3.4 to 11.2 cm. long, from various 

 places in Northern Thailand. The body is marked by seven to nine 

 irregular transverse dark bands, those anteriorly and posteriorly 

 broken into spots or blotches. The dorsal arises very slightly in ad- 

 vance of ventrals and much nearer to tip of snout than to base of 

 caudal fin. 



Fowler (1934a) says: "Characteristic of this species is the dark or 

 black band transversely close before the caudal base," the band else- 

 where being referred to as "at caudal base." As a matter of fact, 

 however, this band is present in a dozen or more Thai and Indian 

 species. 



Fifteen specimens 6.0 to 9.2 cm. long were taken by the Harvard 

 Primate Expedition on Doi Angka, April 1937. These agree rather 

 closely with the originally described specimens from various places 

 in the Meping drainage.
