moult from each of these phases respectively into the gray adult dress. 

 This hawk is confined to the Tropical Zone. All but one of Mr. 

 Smith's specimens were taken at Bonda, the exception coming from 

 Onaca (2,500 feet). A single male was shot by the writer at La 

 Tigrera, in the woodland. 



36. Astur poliogaster (Temminck). 



One specimen : Bonda. 



A female example, secured by Mr. Smith's collector at Bonda, April 

 26, 1899, adds another to the list of known specimens of this excess- 

 ively rare species, and incidentally greatly extends its range, which 

 had heretofore been supposed to be Guiana, eastern Brazil, and Para- 

 guay. For many years this species was known only from the type- 

 specimen in the Leyden Museum, until Gurney (Ibis, 1881, 258) re- 

 corded a second, more fully mature bird. Several years ago the 

 Bonda specimen here recorded was forwarded to the British Museum 

 for comparison with the latter, with the result stated in the following 

 letter from Mr. W. R. Ogilvie-Grant : " I have examined the Goshawk 

 you forwarded for identification. It is of course one of the rarest 

 species of American Astur, and we have only one male example, which 

 is probably not quite fully adult, or rather not an old bird. The 

 cheeks and sides of the neck are greyish-black, and less uniform in 

 tint. I have, however, after a careful comparison, no doubt whatever 

 that your specimen is a fully adult female of Astur poliogaster. It is 

 a beautiful species." 



In 1887 Gurney (Ibis, 1887, 96) described and figured a hawk from 

 an unknown locality under the name Urospizias jardinei, which is 

 nothing more or less than the fully adult Astur poliogaster, as recently 

 shown by Mr. Chubb (Birds of British Guiana, I, 1916, 226). With 

 this description and plate the Bonda specimen agrees well. It meas- 

 ures as follows: wing, 266; tail, 193; bill, 29; tarsus, 61. We pass 

 by for the present the question of this species being properly referable 

 to Astur.

" M. Verreaux informs me that he received several examples of this very 

 distinct species from his collector at Santa Marta. One of them is now in the 

 British Museum, and is the only specimen I have seen of this bird." It turns
