RALLID.E THE RAILS, GALLINULES, AND COOTS. 89 



All these variations appear, however, to be purely individual 

 (perhaps partially seasonal), or at least entirely independent 

 of locality. 



This essentially southern species is comparatively a rare bird 

 in Illinois, though it may be more common than the records 

 show. According to Mr. Nelson, a male specimen was taken in 

 May, 1886, by Mr. C. N. Holden, Jr., near Chicago, and he was 

 informed by Dr. Hoy that a specimen had been captured at 

 Racine. Its general habits are much like those of the Florida 

 Gallinule (Gallinula galeata). 



SUBFAMILY BALLIN-ZE. 

 GENUS BALLTJS LINNJSUS. 



Eattus LINN. 8. N. ed. 10, 1758, 153; ed 12. 1766. 261. Type. E. aquations LINN. 



CHAB. Bill longer than the head, rather slender, compressed; upper mandible slightly 

 curved; nostrils in a long groove, and with a large membrane: wings short; tertiary auills 

 long, frequently longer than the primaries; tail very short; legs moderate; tarsus shorter 

 than the middle toe, and covered on all sides with transverse scales; toes long and rather 

 slender; inner toe rather shorter than the outer; hind toe short and weak. 



This genus contains numerous species, inhabiting all the tem- 

 perate countries of the world. They are very similar in their 

 habits, and frequently in appearance. Their long toes enable 

 them to run over and climb amongst aquatic plants with great 

 facility.
