BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Head, 4 to 4J; depth, 4 to 4§; eye, 2 1 to 3, greater than snout; D. I, 8; A. I, 8 or 
9; scales, 7-38-3, about 14 before the dorsal; teeth, 1, 4-4, 1 or 2, somewhat hooked 
and with evident grinding surface. 
Body moderately elongate, compressed, back little elevated ; head rather heavy, 
snout short and obtuse, mouth large, oblique, lower jaw slightly projecting, maxillary 
extending to below level of pupil; eye quite large, greater than width of interorbital 
space or length of snout; caudal peduncle moderate, its least depth equal to distance 
from tip of snout to middle of eye; fins not large, dorsal inserted behind the ventrals; 
origin of anal behind last rays of dorsal; lateral line continuous, slightly decurved. 
Color: Upper third of body pale yellowish, with numerous small brown specks 
arranged chiefly parallel with the borders of the scales, not presenting a true cross- 
hatched appearance; top of head dark, snout, region about the nostrils, and supra- 
ocular region paler; a dark dorsal line from nuchal region to caudal fin; lower two- 
thirds of body silvery, the upper part being more or less plumbeous forming a broad 
band well defined above, but less so below; lower third of caudal and forward to tips 
of ventrals plain yellowish ; opercles and cheeks very silvery ; breast and lower jaw pale. 
12. Notropis dilectus (Girard). 
Alburnu8 dilectus Girard, Proc. Acad. Nat. Sci. Phi la. 1856, 193 (Arkansas River, near FortSmith). 
Four specimens of what I for the present refer to this species were obtained from 
Long Lake, near Palestine; one from leeches River, east of Palestine; and several hun- 
dred specimens, the largest about 2f inches long, from the Trinity River at Magnolia 
Point. Drs. Jordan and Gilbert obtained specimens of what they referred to Girard’s 
dilectus from the Sabine River, Long Yiew, Texas; Saline River, Belton, Arkansas, and 
from the Arkansas River near Fort Smith. 
Girard’s original description of the species is as follows: 
1. Alburnus dilectus, is about three inches and a half in total length; the head forming a little 
less than the sixth part of it. The greatest depth is nearly equal to the length of the head. The 
diameter of the circular eye is contained a little more than three times in the length of the side of the 
head, and less than once in advance of its anterior rim. There are ten longitudinal rows of scales 
between the insertion of the ventrals and the base of the dorsal. The lateral line is upon the fourth 
row from the ventrals upwards. The color is uniform yellowish red with a lateral silvery streak. 
The types of this species consist of two specimens, 3 and 3f inches long respec- 
tively, and are numbered 71, in the U. S. National Museum catalogue. They are in 
very good condition, and present the following measurements: Head, 4£ (5£) and 4^ 
(5.}) ; depth nearly equal to length of head; eye, ‘U in head in each, longer than snout. 
The specimens obtained by us may be described as follows : Head, 4 to 4£ (5 to 5£) ; 
depth, 4| to 5 (6 to 6J)'; eye, 3 to 3|-; scales, 7-38-3. 
Body slender, compressed, scarcely elevated; head narrow; eye large, greater 
than snout, equal to width of interorbital space; mouth rather large, quite oblique, 
maxillary reaching orbit. 
Dorsal much nearer base of caudal than snout, considerably behind ventrals, high, 
its anterior rays longest, free margin straight; anal larger than dorsal, free margin 
concave; caudal deeply forked; pectorals short, not reaching ventrals, which are also 
short, not reaching anal. Lateral line somewhat decurved. Peritoneum silvery, with 
numerous dark -brown specks. Color, very pale yellowish, side with plumbeous band 
very indistinct on anterior third of side, plainest on caudal peduncle; back and sides 
down to lateral line covered sparsely with small dark specks arranged mostly along
