TWO NEW FORMS OF SURINAM BIRDS 



BY THOMAS EDWARD PENARD 



Verreaux's dove and the yellow-headed caracara are both 

 represented in Surinam by distinct forms which I here propose 

 to separate subspecifically. 



Leptotila verreauxi tenella subsp. nov. 



Type. — Collection of T. E. Penard, no. 2022 (now Museum of Com- 

 parative Zoology, no. 89,294), adult; Surinam: Schotelweg, Lelydorp, 

 26 April, 1922; collected by Alex Pichot. 



Subspecific characters. — Similar to Leptotila verreauxi verreauxi Bona- 

 parte of Colombia, but very much darker. Upper parts, including upper 

 tail coverts and rectrices, much darker and greener, less brownish; white 

 tips of rectrices narrower; exposed parts of remiges blackish; forehead more 

 vinaceous, less whitish. Under parts darker, especially the upper breast; 

 sides of breast much darker and more dusky. 



Measurements (in millimeters). — Type, adult: wing, 126.0; tail, 93.5; 

 tarsus, 25.0; exposed culmen, 17.0. 



Topotype, collection of T. E. Penard, no. 2023, Lelydorp, Surinam, 

 26 April, 1922, adult: wing, 125.5; tail, imperfect; tarsus, 24.0; exposed 

 culmen, 17.0.

 tates Zoologicae, XIII, 1906, p. 47) says they are identical with 

 birds from Venezuela; and Chapman (Bulletin American
