obtained. Head, 4 in the length of the Itody; depth, fit to 6; dorsal, ix or x-10 or 11;

2 in eye. Lateral line incomplete, terminating about half way. Color olivaceous, mottled 
with darker. Nine blackish (irregular) spots on sides. Six dark bauds across the back. 
Dors.al and caudal fins barred; ventrals dark, other fins light. E. ioivw is a very variable 
darter. The specimens here described differ somewhat in form and coloration from speci- 
mens from the northwest. The range known at present is Iowa and Nebraska to BritisR 
Columbia. I am inclined to consider these specimens as E. iowa’, regarding the difference 
here recorded as season.al. These specimens were taken in the spring, evidently near the 
breeding season; other specimens I have examined were collected in the summer and fall.
