H. nigro-fasciata. Le Sueur. The handed Minnow. 

 Journal Academy Nat. Sciences, vol. i. p. 133, 



Several specimens of a beautiful little species answering in 

 the important characters to Le Sueur's ''■ nigro fjsciata" 

 were sent me by Dr. Yale. From the largest of these, I draw 

 up the following description : 



Length of fish two inches. Color above, a yellowish green ; 

 beneath, silvery white, crossed transversely by from ten to four- 

 teen black bars commencing upon each side of the dorsal ridge, 

 and passing down towards the abdomen ; the bands cross en- 

 tirely 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. Eyes less than 

 a line in diameter, which is less than the distance between the 

 eyes. Gill-covers silvery, with a bluish blotch upon the oper- 

 culum. Jaivs 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. 



The Ventrals are quite small, the color of the abdomen ; 

 commencing on a line with the extremities of the pectorals. 



The Anal fin the color of the ventrals ; length to height as 

 1 to 3. 



The Caudal fin is yellowish ; length to height as 1 to 3. 



The fin rays are : D. 12 ; P. 18 ; V. 6 ; A. 12 ; C. 17. 



H. ornata. Le Sueur. The ornamented Minnow. 

 Journal Academy Nat. Sciences, vol. i. p. 131. 



This species of Hydrargira, very common about the salt 

 marshes in the vicinity of Boston, I suppose to be a variety of 

 the " ornata^'^ of Le Sueur. It may be taken in large num-
