 CAMPTOSTOMA OBSOLETUM VENEZUELAE Zimmer 



Cam-piostoma obsoletum venezuelae Zimmer, Amer. Mus, Nov., No. 1109, 1941, p. 

 12 (La Cascabel, Rfo San F61ix, Venezuela). 



SPECIMENS COLLECTED 



1 unsexed, Cantaura, January 8, 1946; iris brown. 



1 9 , Caicara, November 8, 1947; gonads small; iris brown, bill and feet black. 



The Cantaura bird is in very worn plumage; the Caicara example 

 is less abraded. They were collected in semiopcn bushy fields. 



The race venezuelae appears to be of only doubtful validity, but we 

 do not have sufficient material to make a definite decision. 



The collector experienced some difficulty in distinguishing this 

 flycatcher from the preceding form in the field. He considered both 

 to be fairly common at the edges of overgrown fieldsi 



PIPROMOKPHA OLEAGINEA CHLORONOTA (D'Orbigny and Lafresnaye) 



Muscicapa chloronota "Lesson" D'Orbigny and Lafresnaye, Synopsis avium, 

 in Mag. Zool., 1837, cl. 2, p. 51 (Yuracares, Bolivia). 



SPECIMEN COLLECTED 



1 c?, Caicara, July 5, 1947; gonads slightly enlarged; iris brown, feet blue-gray 

 gizzard contained large seeds. 



This specimen is very slightly paler below and, to a still lesser ex- 

 tent above, than a series from southern Venezuela and northern 

 Brazil, but not enough so to warrant considering it as of the race 

 pallidiventris (Hellmayr) of Bermudez, northeastern Venezuela, and 

 Trinidad and Tobago. Hellmayr (Catalogue of the birds of the 

 Americas, pt. 5, 1927, p. 498, footnote) calls pallidiventris an unsatis- 

 factory race at best.

PROGNE CHALYBEA CHALYBEA (Gmelin) 



Hirundo chalyhea Gmelin, Systema naturae, vol. 1, pt. 2, 1789, p. 1026 (Cayenne). 



SPECIMENS COLLECTED 



1 cf , 1 9 , Cantaura, June 28 and August 17, 1947; gonads very small in June 9 ; 

 slightly enlarged in August cf ; iris dark brown ( 9 ), black ( cf) ; gizzards contained 

 small insects; both specimens are in worn plumage. 



This martin was rather common in season, being encountered in 

 small flocks of less than 10 individuals, in all types of open country, 

 not necessarily near water.
