There is considerable variation in darkness or lightness of the 
upperparts regardless of season or sex in birds from the same localities. 
Family CYCLARHIDAE: Peppershrikes 
CYCLARHIS GUJANENSIS FLAVIPECTUS Sclater: Yellow-breasted Peppershrike 
Cyclorhis flavipectus ScLatER, Proc. Zool. Soc. London, vol. 26, 1858, p. 448, part 
(Trinidad). 
SPECIMEN COLLECTED 
lad. &, Venezuela, Soledad, Anzodtegui, December 10, 1929. 
This form is found in northern Venezuela and Trinidad, west to the 
eastern slopes of the eastern Andes of Colombia. The present speci- 
men resembles skins from more northern localities in Venezuela in 
the color of the upper surface, including the crown, but is slightly 
duller yellow below. 
A specimen taken at Ciudad Bolivar, June 8, 1931, was preserved 
in alcohol. 
CYCLARHIS GUJANENSIS GUJANENSIS (Gmelin): Guianan Peppershrike 
Tanagra gujanensis GMELIN, Systema naturae, vol. 1, pt. 2, 1789, p. 893 (French 
Guiana). 
SPECIMENS COLLECTED 
lim. #, lim. 9, Brazil, Mandos, October 1, 1930. 
8 ad. &,4 ad. 9, Venezuela, Puerto Ayacucho, Rio Orinoco, January 2, 1930 
(1 o) and May 11-19, 1931 (all the rest). 
Most of the May adults were noted as having enlarged gonads 
when collected. 
When compared with C. g. flavipectus these birds are distinctly 
darker green on the back, and darker gray on the crown, while below 
the yellow is definitely more greenish. They are identified as typical 
gujanensis in accordance with the recent treatment by Hellmayr 
(Catalogue of the birds of the Americas, pt. 8, 1935, p. 200). Two 
immature birds, fully grown, taken at Mandos, October 1, 1930, are 
still duller green on the breast. It seems not improbable that birds 
assigned to this race may require further division when material comes 
to hand.
