302 New Species of Fish. 



species, however, are very peculiar in their position. Instead 

 of lying obliquely (thus forming the opening of the mouth as 

 in ordinary fishes) they are perfectly horizontal, and as the 

 integuments covering them are thick and project forward in 

 the form of a pointed snout, the mouth becomes, of course, 

 situated beneath the head, almost as in the sharks and other 

 cartalaginous fishes. Leuciscus atronasus of Mitchill ap- 

 proaches more nearly to it in this respect than any other 

 species of the genus with which I am acquainted. To atro- 

 nasus also it appears otherwise somewhat allied. 



The first information we had in regard to this species was 

 obtained from Mr. Charles P. Turner, of Hartford, Ct., who 

 found it in a small stream in West Hartford. It appears 

 there, however, to be rather rare, and the only specimen I 

 have been able to procure from that locality is the one which 

 he first presented to me. But it has since been ascertained 

 to exist in Massachusetts. Mr. C. H. Olmstead recently found 

 it very abundant in some of the streams in Blandford, and to 

 his kindness I am indebted for numerous specimens. Ac- 

 cording to his account of them they inhabit rapid streams, 

 hiding most commonly under stones, from which they often 

 dart out with great speed. All those which he procured were 

 caught with the hook. They struck at the bait with all the 

 quickness and vigor of trout, and might be taken in almost 

 any numbers. The largest which he saw, and which is now 

 in my possession, is five and one fourth inches in length.
