INTRODUCTION. 



31 



In the southern portion of the State, there is observable in some 

 species a marked tendency to the characters of extreme southern 

 races, in smaller size and darker coloration, and, in some species, 

 larger bill. This tendency is especially noticeable in the quails 

 (Colinus virginianus) from the bottom-lands of the lower Wabash, 

 some specimens of which are so much like the Florida form (C. vir- 

 ginianus floridanus] that they have been referred to that race. 



Migrations. Data for the elucidation of this subject are un- 

 fortunately very meagre. While residing at Mount Carmel, the 

 author made careful record of the dates of arrival and departure of 

 many species during the years 1863-'66, inclusive, the results of 

 which are herewith given:
