la. Dorsal rays iii, 10 or 11; mouth inferior with a hard bony sheath or cutting 
edge inside the lips; groove of lower lip not interrupted by a frenum near 
tip of lower jaw; anterior barbel absent or rudimentary; posterior barbel 
shorter than eye concealed when mouth is closed, snout 1°%4 to 2 in head; 
eye above midaxis of head, 534 to 7 times in the head; pelvics inserted under 
the 5th or 6th branched ray of dorsal; scales 35, 5 above and 4 below 
lateral lmesvanal sil, O22 ee See Se ee es Labeo curriei Fowler 
1b. Dorsal rays iii, 8, rarely 7 or 9 branched rays; mouth with the bony cut- 
ting edges inside of the lips. 
2a. Anal rays iii, 10; cheeks 44 covered by the suborbital bones; no barbels; 
scale rows on side of body 42, and 744 above and 1% below lateral 
line; 14 scales around caudal peduncle; 19% in front of dorsal fin; 
pelvic rays 9; pectoral 15; distance from origin of dorsal to midcaudal 
fin base equal to distance from origin of dorsal to occiput (or end of scaled 
region in front of dorsal) ; inner edges of lips finely plicate. Color.— 
Two irregular rows of blackish blotches anteriorly, the lower row end- 
ing with the 6th spot, but the upper row of 14 spots continuing to base 
of caudal fin (one of these on opercle) —~----_- Barilius silex, new species 
2b. Anal rays iii, 5; cheeks less than 44 covered by the suborbital bones, 
two pairs of barbels present; pelvic fin rays 8. 
3a. Fine parallel lines of papillae on sides and top of head, in groups on 
side of snout, cheeks, opercular apparatus, and top of snout; scales 
radiately striated; two pairs of barbels; simple rays of dorsal not 
bony or enlarged, but thin and segmented; suborbital bones narrow; 
lateral line complete; scale rows 22 to 24, usually 23; scales above 
lateral line 344, below 244; scales around caudal peduncle 10, and 
front of dorsal 8, rarely 9; pectoral 16 or 16; pelvics 8. Color.—A 
black band along midaxis of body and on snout, also on midrays of 
caudal fin but more diffuse. 
Mannichthys lucileae, new genus and species 
3b. Parallel lines of fine papillae or pores not occurring in groups on sides 
of snout, cheeks, and top of snout. 
4a. Posterior suborbital bone under rear half of eye enlarged, 3 times 
wider than the adjacent anterior suborbital bone under the front 
half of eye; the expanded suborital bone covers 24 of the cheek the 
next-to-the-last simple ray of dorsal and anal fins movable and con- 
nected to the last simple ray by a membrane similar to that be- 
tween the other rays; dorsal rays iii, 8; rarely iii, 7; scale rows 
25 or 26; 31% above and 2% below lateral line; 12 scales around 
caudal peduncle and 10 in front of dorsal fin; a blackish band along 
midaxis more or less broken into 4 oblong spots. 
Barbus flomoi, new species 
4b. Suborbital bones below eye, both of the same approximate width, and 
narrow, not covering 14 the cheek. 
5a. Three large, roundish black spots along midaxis of body, first in 
front of dorsal, second over anal origin, and third on caudal 
peduncle; scales 24 to 26, usually 25, and 8% above and 2% 
scales below lateral line; scales around caudal peduncle 12, and
