OCT., 1909. BIRDS OF THE LEEWARD ISLANDS CORY. 201 



bases this subspecies largely on the size of the bill and feet, as com- 

 pared with specimens from Cumana, Venezuela, and the Orinoco 

 region (Novitates Zoologicae, Vol. IX, 1902, p. 299). The measure- 

 ments of the Aruba specimens are as follows: 



cJ 1 wing 4.30; culmen 1.14; depth of bill at nostril .43. 



9 " 4-20; " i .08; " " " " " .40. 

 Birds from St. Thomas approach much nearer this form and differ 

 decidedly in color and size of bill from birds from the mainland. The 

 St. Thomas birds must either be considered to be ridgwayi or a new 

 form; they are certainly different from true Icterus icterus. The 

 under parts, collar and ramp are bright yellow, with only a trace of 

 orange, not decidedly orange or reddish orange as in icterus and 

 ridgwayi. The bill averages larger than in either, some specimens 

 having the culmen 1.25. The middle of the outer webs of primaries 

 (except the first and second) are narrowly but distinctly edged with 

 white, while in both icterus and ridgwayi there is merely a trace, and 

 in many specimens from the mainland it is entirely wanting. Should 

 a larger series of specimens prove these differences to be constant, 

 I propose that the St. Thomas bird be recognized as Icterus icterus 

 harterti.
