scribed by Professor Forbes in 1885 from the Wabash and Little 

 Fox rivers in southern Illinois, under the name of L. garmani, 

 but no examples have since been taken in that part of the state. 

 The types of L. garmani Forbes are thin and rather deeply 

 angled at the nape, with pectorals comparatively long, 1.2 to 

 1.4 in head, and dorsal spines rather high, 1.9 to 2.2 in head, in 

 these and all other essential respects agreeing with typical more 

 southern representatives of the species from Missouri, Arkan- 

 sas, and Texas. Specimens of this species taken since 1894 in 

 the Illinois River at Havana and Meredosia have the body more 

 or less robust, dorsal spines short, 2.3 to 2.7 in head, and pec- 

 torals reaching but little beyond the back of the cheek in adults, 

 their length 1.4 to 1.6 in head. These differences are seen to 

 be less important after comparison of specimens from different 

 southern localities, some of which are quite intermediate be- 

 tween the two extremes just described. Southern specimens 

 examined, however, agree in most instances more nearly with 

 the types oiL. garmani than with the form from the Illinois 

 River. 



Lepomis megalotis (Rafinesque).

Generally distributed in Illinois, in the clearer portions of 

 the swifter streams and brooks. 



Lepomis hit mi lis (Girard).

The peculiar structure and coloration of the opercular flap 

 gives to this fish a unique place among the species of the genus 

 Lepomis. 



Widely distributed over Illinois, except in the northern 

 part. 



Lepomis pallidus (Mitchill).

In our collections from Lake Michigan and the streams 

 and lakes of the northern part of the state to the waters of 

 Union county. The most abundant sunfish by far in the Illi- 

 nois River.
