nearly over veutrals. Anal basis short. Lateral line complete. Intes- 
tinal canal short. Peritoneum white. Small, {oipo-oiioj, to feed daintily ;

413. O. ciiiiliae Hay. 
Body rather elongate, moderately compressed, not elevated. Head 
short, slender. Muzzle blunt and rounded. Mouth very small and very 
oblique, smaller than in any other of our Ci/prinidw, with scarcely any 
lateral cleft ; its size, when opened wide, less than that of the eye. Man- 
dible short and deep, strongly curved, jaWs equal. Eye longer than 
snout, 3 in head. Dorsal beginning over posterior rays of veutrals, nearer 
snout than base of caudal. Pectoral very small, not reaching veutrals, 
the latter to anal. Caudal peduncle long and slender. Anal short and 
deep. Breast naked; IG large scales before dorsal. Yellowish; sides 
silvery; scales above dark-edged; a dark lateral band from snout to 
caudal, above and below which are series of black dots; anterior ra.ys 
of dorsal dark; sometimes a black spot on the posterior rays. D. 9; 
A. 8; scales 5-40-3; teeth 5-5, serrate. Eastern Mississippi.

(Forbes, MSS. geu. nov. : type Tryclierodon megalops Forbes.) 
Pharyngeal teeth in one row, 5-5 or 5-6, strongly hooked, deeply 
crenate, without masticatory surface. Lateral line imperfect. Dorsal 
over veutrals. Intestine shorter than head and body. Peritoneum pale. 
Thorax naked almost to veutrals. Mouth terminal, upper jaw protrac- 
tile. 1^0 barbels. (ir^y;/£:/jdr, ragged ; ddwv, tooth.) 
414. T. tiieg^alops Forbes, spec. nov. 
“A small, fusiform species, with a small, terminal, oblique mouth, a 
very large eye, an imperfect lateral line, a narrow black lateral stripe, 
a partly naked breast, and large fins. The dorsal has a large dusky 
black blotch on the front rays. The depth is contained from 4 to 5 
times in the length without caudal ; the head 4^ to 5 times. The eye 
is longer than the snout, and goes but times in the head. Its verti- 
cal diameter equals the interorbital space. The mandible scarcely 
reaches a vertical from the anterior border of the nostril, and falls far 
short of the orbit. The lateral line is variously imperfect ; sometimes 
present only on the first 4 or 5 scales, and sometimes extending, 
with numerous interruptions, to the middle of the caudal peduncle. It
