GrNnus PGICILICHTHYS, Agassiz. 
7. Pocilichthys artesie, Hay, sp. nov. (No. 27,434.) 
In this species the body is more elongated than usual, and consider- 
ably compressed. The head is large and contained in the length to 
caudal fin 53 times; depth in length 5 times. Caudal peduncle con- 
tained in the length of the body 44; its depth one-half its length, 
Mouth large, the maxillary reaching to a vertical from the pupil, 
terminal, nearly horizontal; the lower jaw slightly shorter than the up- 
per. Gill-membrane rather broadly connected across the breast. 
The eye equal to the snout, and contained in the head 4$ times. The 
cheeks are wholly covered with small scales, resembling in this respect 
P. asprigenis, Forbes, from Central Dlinois. The opercles are covered 
with large scales. The scales on the region between the occiput and 
the dorsal fin are very small. 
There are along the sides about 56 vertical rows of scales, 8 horizontal 
rows above the lateral line and 11 below. The lateral line extends 
slightly behind the posterior end of the soft dorsal, being absent on 
about 10 or 12 scales. Just above the base of the pectoral fin, on each 
side, there is an enlarged black scale. 
The two dorsals are contiguous, the membrane of the first reaching 
the second. The fin-rays are, D. XI, 13; A. II, 7. The length of the 
first dorsal, measured from the first to the last spine, equal to the length 
of the head; its height less than half its length. The soft dorsal seven- 
ninths the length of the head; its height about four-fifths its length. 
The anal is in length a hitle more than one-half the length of the head; 
its height also one-half the head. 
The pectoral and ventral fins reach backward to the same point. The 
pectorals are much smaller than in P. ceruleus (Stor.) Ag., reaching 
back only three-fifths the distance from their origin to the vent, while 
in that species they extend backward four-fifths this distance. 
Color.—Sides yellowish olive, with indications of transverse and 
oblique bars of dark, and sprinkled with many small blotches of car- 
mine. Pectorals and ventrals dull blue. Dorsals with a broad band of 
carmine running along the middle, bordered on each side with orange. 
The tips of the dorsals dull blue, as is also the base of the soft dorsal. 
Base of the spinous dorsal with several blotches of carmine. Anal 
mostly crimson, tipped with blue. Candal first’ blue, then orange, then 
carmine, followed by orange, and tipped with blue. The iris is yellow. 
Length of the only specimen obtained 22 inches. 
Irom a small branch flowing into the Catawba, itself tributary to the 
Tombigbee. 
A brilliant little fish, attracting by its bright colors the eye at a dis- 
tance of many feet. 
The palatine teeth of this species form a broad band, whereas in 
P. coeruleus they are few in number and in a single row.
