(4061) Dacnis cayana cayana {Linn.). 

 Motacilla cayana Linn., Syst. Nat., I, 1766, p. 336 (Cayenne). 



I have no specimens from Peru but four adult males and three females 

 from the eastern base of the Eastern Andes cannot, in my opinion, be sepa- 

 rated from British Guiana birds of which we have a large series. The black 

 throat-patch may average greener but the difference is too slight and incon- 

 stant to be of diagnostic value. Females from both localities are indistin- 

 guishable.

This race like many other Tropical Zone birds, occupies the Pacific coast 

 region southward into Ecuador and north and east through Antioquia to the 

 hunid forested area of the lower central Magdalena. As Hellmayr (I. c.) 

 has pointed out Pacific coast specimens are not all typical, most of them 

 averaging paler, an exception, therefore, to the rule that when Pacific coast 

 and Magdalena representatives of a species differ in color those from the 

 former region are darker. 



None of our eight males from the Pacific coast is as dark (i. e. purple) 

 as the most deeply colored of our Magdalena Valley birds. Some, however, 

 of the birds in both series are alike, while the palest of the Pacific coast birds 

 are not distinguishable in color from D. cayana napoea, a form standing 

 between coerebicolor and ultramarina in color. 



Specimens from eastern Panama (Chepigana) are typical of ultramarina, 

 but I agree with Hellmayr that the facts at hand warrant the treatment of 

 all these forms as subspecies of cayana.
