fig. 105 (Pitsanulok, Mepoon). 

 Danio aliolineata Fowler, 1934a, p. 113 (Chantabun). 



Originally taken in 1925 in the waterfall brook at Pliew, on Kao 

 Sabap, Southeastern Thailand, this fish has since been reported by 

 Fowler from Pitsanulok and Mepoon, Central Thailand, and also from

 specimens up to 50 mm. long at Mepoon.
