36 PENARD — TWO SURINAM BIRDS [ P Voi E VTH 



Museum Nat. Hist., XXXVI, 1917, p. 211) does not distin- 

 guish any racial differences between birds from Trinidad and 

 Venezuela, and from Santa Marta, 'Bogota/ the Magdalena 

 Valley in Colombia, Panama, Chiriqui, and Costa Rica. Hell- 

 mayr (Verhandl. Orn. Gesellsch. Bayern, XII, Heft 3, 1915, 

 p. 204) has named the Tobago bird L. v. tobagensis. 



I have examined a large series of true L. v. verreauxi from 

 Colombia in the Museum of Comparative Zoology. 



Milvago chimachima paludivaga subsp. nov. 



Type. — Collection of T. E. Penard, no. 2024 (now Museum of Com- 

 parative Zoology, no. 89,376), adult male; Surinam: Eerste Rijweg, Para- 

 maribo, 19 September, 1921; collected by T. E. Penard. 



Subspecific characters. — Similar to Milvago chimachima cordata Bangs 

 and Penard of Panama, but perhaps smaller; upper parts darker, more 

 blackish, less brownish. Similar also to Milvago chimachima strigilatus 

 Spix of Brazil, but perhaps smaller; under parts warm buffy, not white; 

 base of primaries whitish. 



measurements (in millimeters) 



Besides the Surinam specimens of M. c. paludivaga listed 

 above, I have examined four specimens of M . c. strigilatus from 

 Brazil (Anjos and Boa Vista) and a large series of M. c. cordata 

 from Panama; also six specimens from Rocana, Uassa Swamp, 

 northern Para, Brazil, loaned me by Mr. W. E. Clyde Todd of 

 the Carnegie Museum. These Para specimens are larger (wing, 

 274 to 296), but in coloration they are very much like M. c. 

 paludivaga and, I think, should be referred to this rather than 

 to the white-breasted Brazilian form. Immature birds of the 

 new form, like those of M. c. cordata, have the paler markings 

 of the under parts buffy, less whitish than immature birds of 

 M . c. strigilatus from Boa Vista in corresponding plumage.
