FRESH-WATER FISHES OF SlAM, OR THAILAND 193 



present Province of Laos of French Indo-China, although Giinther 

 assigns it to Cochin China. The species would require no notice in the 

 present connection if Sauvage had not mentioned it incidentally as 

 coming from "Petschaburi" as well as from Laos. Petchaburi is a 

 town in the southwestern part of Central Thailand. Pechabun or 

 Pachebun is a small community on the Pasak River on the eastern 

 border of Central Thailand, a region in which Mouhot made fish 

 collections. The fish was described as having 4 barbels, an ossified 

 and serrated simple dorsal ray, 30 scales in the lateral line and 3 rows 

 of scales between the lateral line and the base of the ventral, and the 

 depth of body one-third the standard length (a feature of little signifi- 

 cance in a specimen so small as the type). Giinther's description 

 would be more or less applicable in part to several Thai species recently 

 named, and the status of this species as a Thai fish is doubtful. 



PUNTIUS BALLEROIDES (Cuvier and Valenciennes) 



Barhus halleroides Cuvier and V.alenciexnes, 1842. vol. 16 (?Siirinara). 

 Barbtis (Puntius) halleroides von Martens, 1S76, p. 402 (Bangkok). 

 Puntius halleroides Sauvage, 1881, p. 163 (nomen nudum) (Bangkok). 



The original description of Barhus 'balleroides^ although quite full 

 for the time, did not bring out characters by which the species might 

 be distinguished from related forms. Recent collecting in Thailand 

 has yielded no specimens that could be referred to this species, said to 

 have the depth 5 in standard length, 4 well-developed barbels, lateral- 

 line scales 30, transverse line scales 13, dorsal rays iv, 8, the last simple 

 ray strong and denticulated, and anal rays iii, 5. Giinther (1868, vol. 

 7, p. 115), copying the description of Cuvier and Valenciennes, placed 

 the species between Bar-bus laoensis (Giinther) and B. sarana (Ham- 

 ilton). 



The species is listed from Bangkok by von Martens (1876) and by 

 Sauvage (1881) but without description, Sauvage simply mentioning 

 the fish as having been collected by Bocourt. Although the collector 

 of the type reported it as coming from Surinam (Dutch Guiana), 

 Valenciennes questioned the locality, and the habitat of the species 

 remains as uncertain as its relationships. 



PUNTIUS SIAMENSIS Sauvage 



Puntius siwmensis Sauvage, 1883b, p. 152 (Menam Chao Phya). 



This species was based on a specimen, 11 cm. long, collected in the 

 Menam Chao Phya by Dr. Harmand. It was characterized by 4 bar- 

 bels, comparatively large scales (28 in lateral line), and a strongly 

 ossified denticulated last simple dorsal ray. The ventrals are said to be 

 below the middle part of the dorsal. The edge of each scale and the 

 tip of the dorsal were black.
