entirely disappear. In the young there is at the base of the anal fin 

 a small black spot that disappears with growth. 



Two figures showing variations in Puntius hinotatus are given by 

 Fowler (1934a) ; his figure 79, however, representing a male fish 18 

 cm. long, does not seem to be this species, as it shows a sharply defined 

 black submarginal band on each caudal lobe, a peculiarity of coloration 

 hot otherwise known in P. hinotatus. It is suggested that this example, 

 together with those from Chiengmai described as having a "spot on 

 gills cherry red. Fins all like sealing wax, dorsal and caudal edged 

 Avith black" may be Puntius orphoides^ a species characteristically 

 marked as stated and moreover having 31 to 34 scales in the lateral line 

 (33 in Fowler's figure), while P. hinotatus has 23 to 27 lateral line 

 scales (26 in Fowler's figure). 



PUNTIUS VERNAYI (Norman) 

 HarhuH rcrnaiii Nokman. 1925, p. 315 (Mewong). 



Described from two specimens, 13.5 and 18.5 cm. long, collected by 

 Arthur S. Vernay in the Mewong east of Umpang in west-central 

 Thailand, this species has not since been recognized. 



PUNTIUS BEASLEYI (Fowler) 



Btirbus leasleyi Fowleb, 1937, p. 194, figs. 153, 154 (Kemarat). 



This species is known from a single speciaiien, 6.2 cm. long, from the 

 Mekong at Kemarat. It has four barbels and plain coloration, but 

 Fowler states that it resembles P. pessulifei^us^ a species with a single 

 pair of barbels, a series of short black vertical bars on the side, and a 

 black spot on the back at the anterior base of the dorsal fin. The closest 

 relationship appears to be with P. vemayi. 



PUNTIUS FOXI (Fowler) 



Barbus foxi Fowler, 1937, p. 188, figs. 144, 145; (Keniarar). 



Described from two specimens, 5.2 and 5.7 cm. long, from the 

 Mekong at Kemarat, Eastern Thailand, and known only from that 

 point, this species is described as characterized by a large black apical 

 blotch on the dorsal fin, with a narrow pale margin anteriorly and 

 distally. 



PUNTIUS HUGUENINI (Bleeker) 



Barbus huguenini Bleeker, 1853 (76), p. 294 (Ombiling River, Sumatra). 



Described by Bleeker in 1853 from a specimen from the Ombiling 

 River in Sumatra, this species has proved to be very rare. In addi- 

 tion to possessing the type, the British Museum has a specimen from 

 Lake Korinche, Sumatra, collected by Robinson and Kloss, and an- 

 other from the Palom River, Pahang, Federated Malay States, col-
