BULLETIN OF THE UNITED STATES FISli COMMISSION. 
Color in spirits: Greenish above, covered with numerous tine, brownish punetula- 
tions, thickest along edges of scales, forming cross-hatching extending about one-fifth 
way down the side; trace of a dark vertebral line: side with a somewhat distinct 
plumbeous band, heaviest on caudal peduncle and ending in most specimens in a 
small but distinct caudal blotch; this baud also extends across opercles, through the 
eye and upon the snout; between this band and the cross-hatching of the back is a 
pale yellowish area, about one scale wide with a few scattered specks showing under 
the lens; body below lateral line pale, with few specks except about base of anal tin 
and along under side of caudal peduncle where they are numerous; tins with few very 
hue dark points. 
Etymology: Latin, nux, nut; in allusion to the 1ST echos River, as Neelies is said to 
mean nut. 
8. Notropis nocomis, sp. nov. 
Head, 4J to 4£; depth, 4f to 5; eye, 3 to 3£; D. I, 8 or 9; A. I, 8; scales, 6-36-3; 
teeth, 1, 4-4, 1, small, hooked, the grinding surface narrow, apparently a little crenate; 
peritoneum silvery, with a few small dark specks. 
Body rather slender, but little elevated; head heavy, resembling that of Cliola 
vigilax; snout blunt and rounded, about equal to eye; mouth small, inferior, horizontal, 
lower jaw included and overhung by the rounded snout; maxillary short, not nearly 
reaching orbit; eye large, equal to interorbital width; preorbital broad; caudal 
peduncle long and slender, its least depth less than half length of head. Dorsal inserted 
directly over the ventrals, high, the longest rays 4 times in length of body, one-fifth 
longer than head, or twice length of fin, reaching middle of anal when depressed, the 
free margin nearly straight; anal resembling dorsal in shape, but smaller, its longest 
rays as long as head; pectorals short, not reaching ventrals; ventrals scarcely reach- 
ing anal fin; lateral line complete, nearly straight. 
Color in alcohol: Yellowish, upper parts of body with numerous fine brown punc- 
tulations, chiefly margining the scales so as to form cross-hatching; lower parts plain 
yellowish; a dark lateral band, faint on the anterior half of side, plainest on caudal 
peduncle; no caudal spot; fins, under the lens, show a few fine specks; top of head 
dark, snout pale. 
This species is described from about 130 specimens, each about 21 inches in total 
length, taken in the Trinity River at Magnolia Point, near Palestine, Texas, and 
five examples from the San Marcos River at San Marcos, Texas. These specimens are 
indistinguishable by me from specimens collected at New Braunfels, Texas, in 1884, by 
Drs. Jordan and Gilbert, and referred to in Jordan’s Catalogue of 1885 under the manu- 
script name Notropis nocomis. In the paper on their Texas collection, these authors 
concluded that their specimens were identifiable with Girard’s Moniana deliciosa, and 
consequently gave no description. 1 obtained numerous specimens at San Marcos, 
New Braunfels, and elsewhere, of what agrees well with the types of Moniana deliciosa 
Grd., with which I have compared them, but they are quite a different fish from that 
for which I adopt the name nocomis. In Notropis nocomis the head is heavier and 
broader, the snout is much more blunt, the mouth smaller and more nearly horizontal, 
and the lower jaw is shorter and included. I have, therefore, thought best to describe 
this form as a new species, adopting for it the manuscript name of Jordan and Gilbert. 
In the Trinity River, at Magnolia Point, this species was found in great numbers 
on a ripple when the current was pretty strong.
