From the Chickasawha at Enterprise. Caught for bait for larger 
fishes, and called ‘‘ Bull Heads”. 
While this species must resemble H. tuditanus, it evidently is distinet 
from it. The dorsal fin of that species is said to be markedly nearer to 
the caudal than to the end of the muzzle, while the contrary is true in 
my species. If the horizontal rows of scales have been counted cor- 
rectly, and in the same way in both species, there is one more row above 
the lateral line in mine than in Professor Cope’s species. The mouth in 
H. tuditanus is said to be very small and inferior, as in Hyborhynechus 
notatus. The latter feature certainly does not belong to the present 
species. 
31. Alburnops longirostris, Hay, sp. nov. (No. 27,440.) 
The general appearance of this species is much like that of small 
specimens of Hricymba buccata. 
Head rather small, contained in the body 435 times. Eye small, being 
contained in the head 4 times; not equaling the snout, which is one- 
third the length of the head. The upper jaw is rounded and much 
overlaps the lower jaw. The mouth, therefore, inferior, rather large, 
horizontal. The maxillary attains a vertical from the anterior of the 
orbit. Teeth 4-4, hooked, and having a triturating surface. 
Lateral line somewhat decurved. Scales large, there being 36 along 
the lateral line, 4 horizontal rows above, and only 3 below. About 12 
large scales in front of the dorsal. Depth in length 4? to 5. 
Origin of the dorsal fin midway between the tip of the snout and the 
base of the caudal and directly over the insertion of the ventrals. Rays 
of dorsal I, 8; anal I, 7. Dorsal nearly twice as high anteriorly as long; 
anal short and low. Caudal deeply forked, nearly one-fourth the length 
of the body. Pectorals far from reaching the ventrals; these extend- 
ing fully to the vent. 
Caudal peduncle in body 3? times; its greatest width nearly one-half 
its length. 
This fish is of a pale straw-color, slightly dusky from the brown edges 
of the scales. There is a very narrow, dark dorsal line; also an obso- 
lete lateral band just below the lateral line. Top of the head brown; 
the vertical fins dusky. 
eneth of the largest specimen 2 inches. Seined in considerable 
numbers at Enterprise. The females teem with eggs. 
32. Alburnops xzenocephalus, Jor. (No. 27,435.) 
Hyboypsis cenocephalus, JORDAN, Annals N. Y. Lye. Nat. Hist. 1877, 335. 
Alburnops xenocephalus, JORDAN, Bull. U. S. Geol. Surv., vol. iv, No. 2, 420 
Several specimens of a dark-colored minnow were seined at Enter- 
prise the resemblance of which to H. «enocephalus is so close that I have 
referred them to that species, so well described by Professor Jordan in 
his *‘ Fishes of Upper Georgia”. There are some differences, however, 
that I have thought worthy of mention.
