The long nosed dace or Niagara gudgeon is found in New 

 England and the Middle states, and in the Great lakes region in 

 clear, cold water. In Pennsylvania, according to Cope, it is 

 limited to the rapids and swift waters of the eastern part of the 

 state. 



Evermann and Bean collected 50 specimens in Saranac river, 

 Plattsburg N. Y. July 28, 1894, but did not find it in the St 

 Lawrence river or in the Lake Ontario tributaries. Though Dr 

 Meek obtained no specimens of this species from Cayuga lake 

 basin, he believes it a member of the fauna, as it is common in 

 the streams south of Ithaca near Van Ettenville, Chemung co. 

 N. Y. 



The long nosed dace frequents rapids and rocky pools, and is 

 associated in mountain regions with the brook trout. Its move- 

 ments are swift and powerful and it is a very shapely little fish. 

 As a bait for the black bass it is scarcely surpassed.

The black nosed dace has a moderately long and stout body, 

 with a broad back, and rather small conical head. The greatest 

 depth of the body is contained four and one fourth to four and 

 one half times in the total length without caudal. The least 

 depth of the caudal peduncle equals one half greatest depth of 

 body. The head is one fourth as long as the fish to caudal base; 

 its width is about one half its length and the snout nearly one 

 third to two sevenths. The eye is as long as the snout and 

 much less than width of interorbital space. The mouth is small,
