TOR DOURONENSIS (Cuvier and Valenciennes) 



Barhus douronensis Cuvier and Vauenciennes, 1842, vol. 16, p. 187 (Java). 

 Barius duoronensis Boulenger, 1903, p. 303 (Patani River). 

 Labeobarbus duoronensis Smith, 1031d, p. 185 (Patani River). 

 Labeobarius douronensis Fowlke, 1935a, p. 120 (Srisawat). — Koumans, 1937a, 

 p. 63 (Tale Sap). 



This species, previously known from Sumatra, Java, and Borneo, 

 was added to the Thailand fauna by Annandale and Robinson, who 

 collected three specimens in the Patani River that are now in the 

 British Museum. These specimens, recorded by Boulenger under the 

 name Barhus duoronensis., came from the Patani River between 

 Biserat and the town of Patani. Most unexpectedly, the fish was 

 found by the writer in the Mekhan, a tributary of the Meping, in the 

 Northern district, a specimen 31.5 cm. long being taken February 6, 

 1932. Another record is for Srisawat, where R. M. de Schauensee took 

 a specimen of 14 cm. in July 1934. A specimen about 15 cm. long is re- 

 corded by Koumans from the inner lake of the Tale Sap at Patalung. 



The fishermen along the Mekhan know this fish and give it a special 

 name, fla ngien. 



TOR STRACHEYI (Day) 



Barbus stracheyi Day, 1871, p. 307 (Akyab, Moulinein). 



This fish, recorded from Akyab and Moulmein in Burma, occurs 

 in the Salwin Basin in Thailand. An example, 22.5 cm. long, taken 

 by the writer in the Mepai near Mehongsorn, June 27, 1932, agreed 

 well with Day's description and plate. 



The fish is not rare in the Mehongsorn district and is called pla yard 

 by the local fishermen.

A fish of Java and Sumatra, this species was first detected in Thai- 

 land in 1925 when a small example was taken in the waterfall stream
