FRESH-WATER FISHES OF SlAM, OR THAILAND 295 



Salwin, October 14 and 15, 1936, show 5 regular black cross lines 

 on the caudal fin. 



A lot of 13 specimens, 4.7 to 7.1 cm. long, taken in the Menam Mao 

 December 26, 1936, at a point where the river was a torrent, is note- 

 worthy for the intensity of the dark brown markings on head, body, 

 and fins. The caudal fin has 4 or 5 regular V-shaped bands, and the 

 anal, ventral, and pectoral fins, which do not appear to have been pre- 

 viously described as having any markings, are banded with rows of 

 spots on the rays. 



This species has usually been called Lepidocephalus hasselti (Cuvier 

 and Valenciennes, 1846). Those authors, however, based their de- 

 scription on a drawing sent from Java by Kuhl and van Hasselt and 

 made no mention of the fact that van Hasselt had already given the 

 name L. octocirrhus to the same fish in 1823. Weber and de Beaufort 

 (1916, vol. 3) rejected van Hasselt's name because of "insufficient 

 description," but the fact that the fish was recognizable from the de- 

 scription would seem to validate the name. Bleeker (Atlas Ichthy- 

 ologique, 1863 (301), vol. 3, p. 13) placed L. octocirrhus in the 

 synonymy of Z. hasselti without comment. 



A variety of names is borne by the fish in different parts of its 

 Thai range: pla sai (sand fish) in Nakon Sritamarat, pla rrvu (hog 

 fish, in allusion to the tusklike spines), in Bung Borapet, pla chon 

 (literally, sideways-moving fish) in the Meping at Chiengdao, and 

 pla hluey in Chantabun. 



LEPIDOCEPHALUS CATARACTUS Fowler 

 Lepidocephalus cataractus Fowlee, 1939, p. 60, fig. 10 (Trang). 



Numerous specimens of this fish were available to Fowler in describ- 

 ing the species, all from the waterfall stream near Trang, in Peninsular 

 Thailand. The principal characters are shown in the key. 



Maximum length, 8.4 cm. 



LEPIDOCEPHALUS BERDMOREI (Blyth) 



Syncrossus ierdmorei Blyth, lS60b, p. 166 (Tenasserim). 



Lepidocephalus berdmorei Suvatti, 1936, p. 60 (Meklong).^KouMANS, 1937a, p. 63 

 (Peninsular Siam). 



Otherwise known only from Burma, this species is simply listed 

 by Suvatti from the Meklong but it is definitely reported by Koumans 

 from Takuapa, on the west side of Peninsular Thailand, two speci- 

 mens, 7 and 7.8 cm. long, having been examined in a collection of 

 Thailand fishes sent to the Natural History Museum in Basle, Switzer- 

 land, by Dr. H. Bernatzik. Several specimens collected from time 

 to time for the Siamese Bureau of Fisheries in Peninsular and North-
