 GARRA FASCIACAUDA Fowler 



Garra fascia cauda Fowlke, 1937, p. 212, figs. 187, 188 (Kemarat). 



Known from numerous specimens, 7.5 to 11 cm. long, from the 

 Mekong at Kemarat, Eastern Thailand, this species is conspicuously 

 marked by a narrow sharply defined black submarginal stripe extend- 

 ing nearly the full length of each caudal lobe, in addition to a broad 

 black band along the middle of the side. The fish is rather slender 

 (depth 5.2 to 5.3 in standard length). The caudal peduncle is about 

 as long as the head and 1.5 to 2 times its own length. From 16 to 20 

 plaits form the edge of the upper lip. The U. S. National Museum 

 has 2 specimens received from the Academy of Natural Sciences of 

 Philadelphia. 



GARRA PARVIFILUM Fowler 



Garra parvifilum Fowlfjr, 1939, p. 73, figs. 21, 22 (Trang). 



Known from several specimens, 11.7 to 14.4 cm. long, from a water- 

 fall stream near Trang in Peninsular Thailand, this species is very 

 similar to G. taeniata in coloration but appears to differ in having a 

 somewhat broader, more rounded snout that is shorter in its preoral 

 aspect, and in having a much shorter caudal peduncle whose length 

 scarcely exceeds its depth. The rostral barbels (referred to in the 

 description as maxillary) are shorter than the diameter of the eye, 

 while in typical G. taeniata they are much longer, but this appears to be 

 a variable character in that species, and examples are met with in which 

 the barbels are shorter than the eye. 



GARRA FULIGINOSA Fowler 



Garra fuliginosa Fowler, 1934a, p. 139, figs. 108-11 (Metang). 



The type of this species, the only specimen known, was taken in the 

 Metang, north of Chiengmai, Northern Thailand, in January 1933 ; it 

 is 17.8 cm. long. Tlie oustanding specific features are the possession 

 of two pairs of barbels, a deep transverse rostral groove, and plain 

 coloration. 



Genus DISCOLABEO Fowler 



Discolaleo Fowler, Proc. Acad. Nat. Sci. Philadelphia, vol. 89, p. 210, 1987. 

 (Type, Discolaheo fisheri Fowler.) 



The genus Discolaheo, as described and figured by Fowler, differs 

 from Garra in having an entire, instead of a crenulated, upper lip and 

 the disk is not margined with a continuous band of papillae. The po- 

 sition of the eye, entirely in the anterior half of the head, seems to 

 be another differential feature. In other respects Discolaheo closely 

 resembles Garra.
