CUNCUMA VOCIFER CLAMANS (Brehm) 



Haliaetos damans Beehm, Jouru. f. Ornith., 1853, p. 199, footnote : No definite 

 type locality; I designate Shoa. 



Specimens collected: 



Female, Duletcha, Ethiopia, January 25, 1912. 



Male, Lake Zwai, Ethiopia, March, 1912. 



Brehm ^^ described a small race of this bird from the Sudan and 

 northeastern Africa and named it damans. Recent writers have been 

 far from uniform in their treatment of this form; some, such as 

 Zedlitz, recognizing it, others, as Sclater, Reichenow, etc., consider- 

 ing it not valid. 



Purely on geographical grounds the two specimens listed above 

 should be damans if that form be valid. 



The form was characterized by Brehm as being considerably 

 'smaller than typical vocifer, the females of the former being no 

 larger than males of the latter, and the males of damans smaller 

 still. Zedlitz ^* gives the following size criteria : Wing length of typi- 

 cal vocifer, 520-550 in the male, and 563-580 millimeters in the 

 female; of damans, 500-505 in the male, 620-530 in the female. 

 Erlanger -^ gives similarly small figures for northeast African birds 

 Of the two birds collected by Mearns, the male has a wing length of
