r. Description of a New Species of Darter from Tippecanoe 



Lake. 



W. J. MOENKHAUS. 



During the summer of ISDC. while collecting large quantities of Per- 

 cina caprodes in Tippecanoe Lake, a single large specimen of darter was 

 taken which could not be identified with any described species. I thought

 caprodes and Hadropterus aspro becaWe of evident intermediate charac-

 specimens might be taken, I last year published a note in the Proceeding's
