FRESH-WATER FISHES OF SIAM, OR THAILAND 223 



Dangila kuhli (now Labiobarbus kuhlii) but that it appeared to 

 differ therefrom in having a shorter head and fewer scales between 

 the dorsal fin and the lateral line. In a recent examination of speci- 

 mens from Tanoy in the Indian Museum in Calcutta. Dr. Sunder Lai 

 Hora determined the number of circmnpeduncular scales as 16 and 

 the pharyngeal teeth as 5,4,2-2,4,5, thus agreeing with Weber and 

 de Beaufort in the formula for the teeth in their generic definition, 

 rather than with the formula 5,4,3-3,4,5 noted by Day. 

 The Malay name given to the fish at Patani is ikan tubu. 



LABIOBARBUS SUMATRANUS (Bleeker) 

 Dangila sumatrana Bleeker, 1852 (67), p. 506 (Solok, Sumatra). 



There are a few Thailand records for this fish, otherwise known 

 only from Borneo and Sumatra. The species was first observed in 

 the Chantabun River, Southeastern Thailand, April 10, 1925, and 

 three specimens were preserved. A specimen was taken in the Men am 

 Wang at Lampang November 17, 1928. A third locality is Klong 

 Chawang, east of Bandon in Peninsular Thailand, where the late 

 R. Havmoller collected a specimen in February 1929. 

 '"'The length of the fishes examined has ranged from 12 to 16 cm. 



In the vicinity of Lampang the name for the fish is pla huk lien. 



LABIOBARBUS LINEATUS (Sauvage) 



Dtiiigila Imeafn Sauvage, 187Sb. p. 287 (Stung-Strang, Laos). — Smith, 1933a, p. 

 80 (Tapi River, Chantabun River). — Fowler, 1934a, p. 115 (Chiengmai, 

 Chiengsen). 



Originally known only from what is now French Indo-China, this 

 species in recent years has been found in Peninsular Thailand (Tale- 

 Sap and Tapi River near Bandon), Southeastern area (Chantabun 

 River), and Northern district (Chiengmai and Chiengsen). In the 

 Tale Sap the fish is common, reaching a length of 15 cm. A specimen 

 from the Tapi River was courteously examined by Dr. L. F. de Beau- 

 fort at the Zoological Museum in Amsterdam and foiuid to be in agree- 

 ment with Sauvage's description. 



In the Chantabun River in May 1929 the fish was very abundant 

 and in spawning condition ; two ripe males 17 and 17.5 cm. long had 

 iarge rostral tubercles and minute pearl organs on top of head and 

 predorsal region. Many small buckets of ripe or nearly ripe eggs, 

 lightly salted, were exposed for sale in the Chantabun market. 



This species may be recognized by two transverse rows of rostral 

 pores or tubercles on pores, and six to nine dark longitudinal stripes 

 following the rows of scales. 



In the Tale Sap this fish shares with other members of the genus the 

 name p?a ta deng {ta deng, red eye). In the Bandon district the ver- 

 nacular name is jda lao tong {Jao fong, golden spear). At Chantabun
