FAMILY PSITTACIDAE 95 



Status uncertain. Known in Panama from 2 records from Darien 

 in the lower Tuira area (Tapalisa; Cituro). 



Inclusion of this species is based on 2 specimens, both females, in 

 the American Museum of Natural History taken by W. B. Richardson 

 in 1915. One was collected at Cituro, back of Boca de Cupe, on 

 May 13. The other, from Tapalisa, according to Griscom, was taken 

 March 17. The label on the specimen bears only the date 1915. It is 

 known from other material that Richardson was at Tapalisa from 

 February 16 to March 18 so that this bird must have been collected 

 during that period. 



The species is one of wide range across northern Colombia to 

 northwestern Venezuela. 



Dugand (Caldasia, vol. 5, no. 21, March 20, 1948, p. 183) has desig- 

 nated the type locality as the Sierra Negra, in the northern Sierra de 

 Perija. The locality "Rio Acha" (Riohacha) on the coast of north- 

 eastern Colombia, given by Bonaparte in his original description, can- 

 not be correct since the bird does not range in that semiarid section. 

 It is presumed, therefore, that the type specimen came from the moun- 

 tain forests to the south where these parrots are common.
