From the Chickasawlia at Euterpiise. CaugUt for bait for larger 

 fishes, and called "Ball Heads". 



While this S[)ecies must resemble H. tuditanuSj it evidently is distinct 

 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 Hyhorliynchus 

 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 Ericymha buccata. 



Head rather small, contained in the body 4:^ 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 3G along 

 the lateral line, 4 horizontal rows above, and only 3 below. About 12 

 large scales in front of the dorsal. Depth in length 4f| 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. 



Length of the largest specimen 2 inches. Seined in considerable 

 numbers at Euteri)rise. The females teem with eggs. 



32. Alburnops x3Baoc9p!ialus, Jor. (No. 27,435.) 



Hybopsis xwaocephalus, Jordax, Annals N. Y. Lye. Nat. Hist. 1877, SS.'). 

 Alburnops xoenocephalas, Jordan, Bull. U. S. Geol. Snrv., vol. Iv, No. 2, 420 



Several specimens of a dark-colored minnow were seined at Enter- 

 prise the resemblance of which to H. .vccnocephalus 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 difl'erences, however, 

 that I have thought worthy of mention.
