BARILIUS KORATENSIS H. M. Smith 



Figure 24 



BariUus koratensis Smith, 1931a, p. 16, fig. 7 (Menam). 



Kiiown from a single specimen, 6 cm. long, from the Menam Mun 

 at Ta Chang, in Korat Province, this fish is easily recognizable by the 

 absence of barbels, the insertion of the dorsal fin almost wholly in 

 advance of the anal, and the presence of two black vertical bars on 

 the side, one over the pectoral, one under the dorsal.

BARIUUS ORNATUS Sauvage 



Barilius ornatus Satjvagb, 1883b, p. 153 (Menam Chao Phya). 



Described from a specimen, 11 cm. long, collected in the Menam 

 Chao Phya by Dr. Harmand, this species does not appear to have been 

 met with again. The description is imperfect, and a number of fea- 

 tures of diagnostic value are not referred to. There are no barbels, 

 the body is comparatively deep (3 in length), the maxillary extends 

 to a line drawn vertically from the pupil, the scales in the lateral line 

 number 45, the origin of the dorsal fin is midway between the pupil 

 and the base of the caudal, the origin of the anal fin is opposite the 

 termination of the dorsal base, and the body is marked with 12 trans- 

 verse steel-blue bands. 



BARILIUS GUTTATUS (Day) 



Opsarius guttatus Day, 1869, p. 620 (Burma). 



Bola harmandi Sauvage, 1880, p. 231 (Cambodia) ; 1881, p. 188, pi. 6, fig. 6 (Cam- 

 bodia). 



Barilius harmandi Fowlee, 1934a, p. 141, figs. 112, 113 (Chiengmai) ; 1935a, p. 130 

 (Sriracba) ; 1937, p. 212 (Mepoon). 



Originally described from Burma, this species was added to the local 

 fauna when specimens were collected in 1924 by Dr. Malcolm Smith 

 from a hill stream near Kaheng on the Meping in Central Thailand.
