BULLETIN 01 THE UNITED STATES FISH COMMISSION. 69 



Teeth 2, 4-4, 2, without hook and with a masticatory surface; appear- 

 ing to differ from those of Sybognathm only in being in two rows. 



Lateral line complete, running rather low anteriorly. Transverse 

 rows of scales 38. Of the horizontal rows of scales there are five 

 between the lateral line and the front of the dorsal, and three between 

 the lateral line and the base of the ventrals. Dorsal I, 8; Anal I, 7. 

 Dorsal slightly nearer the base of the caudal and the snout, beginning 

 slightly in front of the ventrals, rather high, four-fifths the length of 

 the head; its length one-half the same unit. Anal small; its height 

 scarcely two-thirds the length of the head; its length about one-third 

 the head. 



Caudal peduncle short, contained in the length of the body nearly 5 

 times; its depth about one-half its length. 



Color in spirits a clear yellowish green. The lower jaw, the sides of 

 the head, and the body below the lateral line silvery. On the scales 

 above the lateral line from head to tail there is a great number of minute 

 black dots. A few of these occur just below the lateral line anteriorly, 

 while on the hinder half of the body these punctulations are condensed 

 into a dark line just above tbe line of pores. A row of black points 

 arises at the beginning of the anal, and runs on each side backward to 

 the base of the caudal. Top of the head dusky, fins pale. 



A siugle specimen, 1^ inches long, was obtained in the Pearl River 

 at Jackson, Miss. 



38. Alburnops taurocephalus Hay. — Bull-headed Minnow. 



This minnow appears to have a wide distribution in the South. I 

 obtained specimens of it at Memphis, Vicksburg, Jackson, and Grenada. 



39. Alburnops xaenocephalus Jor. 



Numerous specimens of this species were seined in the vicinity of 

 Jackson. 



In the autumn of 1881 I received from Mr. W. A. Warner, of Enter- 

 prise, Miss., a number of fishes which had lain in alcohol but a short 

 time. Among these were several belonging to this species which showed 

 some peculiarities of coloration that I have not seen described. The 

 ground color on the upper half of the body is olive, below it is pale. A 

 blue band runs along the side, palest on the anterior half, deepeniug 

 posteriorly to indigo, and ending at the base of the caudal in a spot of 

 the same color. Top of the head, opercles, and a band across the snout, 

 leaden blue. Snout above the blue band rosy. Tip of lower jaw blue. 

 A dark blue stripe along the back, broadest in front of the dorsal. 

 Body below the lateral line white, except that there is more or less 

 blue on the belly, and a blue streak on each side of the anal fin. The 

 dorsal and the caudal fins are red. 



40. Alburnops longirostris Hay. — Long-nosed Minnow. 



No specimens of this species were found on my last excursion. 1 have 

 additional specimens from the Chickasawha River at Enterprise. In
