CARMAN: PISCES. 115 



of the upper surface. Mouth large, inferior, outline somewhat arched trans- 

 versely; upper lip fringed, connected at the angles with a fold passing a short 

 distance behind that at the hind edge of the disk; jaws sharp-edged. The 

 deep transverse groove in front of the disk, behind the lower jaws, is not con- 

 tinued at its sides. No barbels. Pectorals short, reaching more than half 

 way to the ventrals. Middle of dorsal base half way from snout to base of 

 caudal; fin as high as long, hind margin deeply indented. Ventrals shorter 

 than the dorsal, but extending a little farther backward, origins below the 

 eighth ray of the dorsal. Anal smaller than the ventrals, origin midway be- 

 tween the bases of the ventrals and the base of the caudal. Caudal deeply 

 notched. Total length 10.5 inches. 



Lower surfaces uniform yellowish; back darker yellow to brownish, each 

 scale with a transverse darker streak on its forward portion, those on the 

 lateral line a little more distinct. 



The generic diagnosis of Garra being modified so as to include G. imberba, 

 with Bleeker's subdivisions, based on the number of barbels, the subgenera 

 Garra, with four barbels, Discognathus with two, and Ageneiogarra with no 

 barbels, are readily distinguished.

Slight differences from the type are to be seen among these specimens. 

 Head short, about one fifth of the length to the base of the caudal, moderately 

 broad, blunt, arched from the snout to the eyes and across the interorbital 

 region. Eye one fourth of the length of the head, in front of its mid length. 

 No barbels. Mouth large, arched, reaching the sides of the head below 

 the eyes; lower jaws very strong, with a slight knob below the symphysis; 

 upper jaws thin and protrusive (downward); upper lip thin, distinct. Pectorals 

 small, pointed, reaching a vertical from the origin of the dorsal. Dorsal with 

 a strong serrated spine, the fourth ray longer than the head, hind margin of 

 fin concave, angles acute, middle of base in the middle of the total length with- 

 out the caudal. Ventral origin below the sixth dorsal ray, outer angle acute. 

 Anal short, pointed, origin midway from the origins of the ventrals to the base 

 of the caudal, third ray as long as the head. Caudal deeply notched, lobes
