Species nova. 
Body deeper than thick, the dorsal outline not at all elevated. Head 
elongate not more than one-fourth the length to base of caudal, the orbit 
small and bordering the frontal plane. Preorbital region most elongate 
in the genus ; muzzle truncate in promile ; the upper lip hanging free, the 
lower deeply incised behind so asto be A shaped, and with the upper, finely 
granular, not plicate. The muzzle very projectile, more so than in any 
species of the genus. The top of the cranium is everywhere plane. Dorsal 
fin truncate, with XII radii. Scales large, about as in P. coLLAPsus, 
Cope, i. e. B—42—5. 
Color everywhere a silvery white, except some blackish shades at the 
bases of the scales of the dorsal region. The fins, unlike those in most 
other species, are pure white in life. They attain one foot in length, and 
do not exceed one pound in weight. : 
This species is quite abundant in the Catawba and Yadkin Rivers, in 
North Carolina, and is highly valued by the inhabitants as an article of 
food. It is regarded as the best of the Catostomi for this purpose. It is 
less frequently caught on a hook than some other species, but in the 
autumn they come on the weirs in considerable numbers ; from these I 
procured many specimens. The fishermen call it the ‘‘Shiner.’’ Its char- 
acters are very constant, and not likely to be confounded with those of any 
of the known Ptychostomi. ' 
Ptychostomus velatus, Cope. 
Species nova. 
This is a stout species, with a short head, large eye, and more than 
usually elongate dorsal fin. Scales 5-6-——-42——5 ; head scarcely 4 times 
in length; superior plane nearly flat ; orbit 3.75 times in length of head ; 
1.5 times in interorbital width. D. XVI. with straight.superior margin ; 
Vv. IX. Upper lip pendent. Dorsal outline arched to the first dorsal ray ; 
greatest depth 3.2 lines in length (exclus. caudal). Total length 11 
inches.
