rather short, oblique. Length of gill-rakers equals two-thirds the diam- 

 eter of eye. Insertion of dorsal about midway between root of caudal 

 fin and anterior border of eye. Caudal peduncle robust. Caudal fin 

 deeply forked. Anal moderate, with basal sheath, the length of its base 

 4f in head. Pectorals nearly 2 in head. Ventrals short, 3 ; V in head. 



Color in spirits slightly olivaceous ; side with a sharply defined silvery 

 band, about as wide as eye, more distinct than in our other species. 

 Snout yellowish ; top of head dusky; sides of head lustrous silvery; 

 caudal light, with many dark points ; dorsal little dotted; anal and pec- 

 toral scarcely specked. Described from numerous specimens from 

 Beaufort, N. 0., and a specimen from the coast of Brazil. The specimens 

 obtained by Professor Baird at Beesley's Point, New Jersey, belong to 

 this species. 



Giinther's description of Engraulis mitchilli does not conform to 8. 

 broicni in depth of body and in the number of anal rays; these char- 

 acters probably indicate a confusion with E. mitcMlli C. & Y. Engraulis 

 hiulcus Goode and Bean differs from S. broicni in a body less deep and 

 in having two more rays in the anal — differences which scarcely sustain 

 the validity of the species.

ON A COULECTION OF FISHES FROM THE LOWER MISSISSIPPI 



VALLEV. 



m 



By O. P. HAY. 



The fishes described in the following paper were collected mostly by 

 the author during the summer of 1881. The first point visited was 

 Memphis, Tenn. My collections there were made during the latter part 

 of June, on the Arkansas side of the river. The seining was done there, 

 as I was obliged for the most part to do it elsewhere, in the shallow 



*This species differs from E. broicni in having the dorsal fin entirely anterior to tlie 

 anterior ray of the long and deeply concave anal and in the serration of its belly.
