H. nigro-fasciata. Le Sueur. The banded Minnow. 
Journal Academy Nat. Sciences, vol. i. p. 133. 
Several specimens of a beautiful little species an- 
swering in the important characters to Le Sueur’s 
* migro fasciata,” were sent me by Dr. Yale. From 
the largest of these, I draw up the following descrip- 
tion : 
Length of the fish two inches. Color above, a yel- 
lowish green; beneath, silvery white, crossed trans- 
versely by from ten to fourteen black bars commenc- 
ing upon each side of the dorsal ridge, and passing 
down towards the abdomen; the bands cross entirely 
the fleshy portion of the tail ; in front of the ventrals, 
they reach only the lateral edges of the abdomen. 
Length of the head half an inch. Head flattened 
above. yes less than a line in diameter, which is 
less than the distance between the eyes. Gill-covers 
silvery, with a bluish bloteh upon the operculum. 
Jaws very projectile ; the lower slightly in advance 
of the upper. 
The Dorsal fin is just back of the middle of the 
body ; transparent; greenish white; height equal to 
its length. 
` The Pectorals are lighter colored than the dorsal ; 
length to height as 1 to 4. W
