314 Notes on the 



52. ETHEOSTOMA FliABELL. AREt Rafinesqae. 



(Fan-tailed Darter.) 

 A., 237. B., 518. C, 80. 



Found with the preceding. These two are the only species of 

 darters found. It seems very strange to me that even these 

 were not found in the streams on the uplands. 



Darters frequent shallow running water, especially if it is 

 clear and the bottom of the stream is rocky. 



Such are the characters of the upland streams near Ithaca. 



Both Six Mile Creek and Fall Creek flow from the uplands to 

 the lake in a series of cascades. It is impossible for fishes to 

 ascend these falls, even in the case of high water. This fact 

 gives considerable interest to the study of the fishes of these two 

 streams; and the same is true of Oascadilla and Buttermilk 

 creeks.
