The Blue-breasted Darter is rather rare in Ohio, although it 

 has been taken at a number of widely separated localities, which 

 would indicate a general distribution. It is found in company 

 with E. zonule, on swift, stony ripples, but is much less frequent 

 in occurrence. Jordan mentions it for the Mahoning river ;

 Very rare. The species was described in 1838 from speci- 

 mens taken in the Mahoning river by Dr. Kirtland. I know of 

 but one subsequent record of its capture within the state. Mr. 

 K. B. Williamson and the writer took a single specimen, a female 

 with ripe eggs, from a swift ripple in Big Walnut creek, near 

 Lockbourne, Franklin County, on June 26, 1897.
