belongs to the eastern race, P. s. cohimhianus, having the malar 

 streak and a broad stripe down the middle of the lower surface, 

 from the chin to the anal region, clear white, and the ruonp as 

 well as the upper tail-coverts uniform ochraceous buff ; the two 

 others, labelled " Ecuador — Jameson," agree with the so-called 

 "■ berlepschi" irom. W. Ecuador, having the malar streak bright 

 buff, the rump feathers green with buff edges, and the whole of 

 the lower parts, with exception of a white stripe along the middle 

 of the throat, ochraceous buff. As will be easily seen from Gould's 

 account, his description is a mixtiim compositum, the characters 

 of the lower parts (" chest, abdomen, and under tail-coverts rich 

 buff") being taken from the western form (berlepschi), while the 

 words ^^ rump and upper tail-coverts rich buff" apply only to 

 the eastern coluinbiaiius. Since no marked type of P. syrmato- 

 phorus exists, M. Boucard was perfectly justified — according to 

 the rule of the fii'st reviser — in restricting the name to one of 

 the components, and his name columhianus has to stand for the 

 eastern race. Thus Ave have : — 



(a) P. s. syrmatophorus (Gould) (syn, berlepschi Hart.). 



Western Eciiador (Gualea, Rio Pescado, etc.) and Western 

 Cordillera of Colombia (La Selva, La Tigra, Las Cruces, 

 Medellin, Santa Elena, etc.). 



(b) P. s. coluinbianus Boucard. Eastern Ecuador (Rio Pastaza 



etc.), and Eastern Cordillera of Colombia (Bogota coll.).

This bird belongs to E. a. heterura, as defined by Hartert &. 

 Hartei't*, having much less white in the tail than Bogota-skins 

 ( = true E. a. aquila). Messrs Salvadori & Festa t cast some 

 doubts on the distinctness of E. baroni Hart. & Hart. +, and 

 take this " species " for the young of the ordinary heterura (sensu 

 Hartert). I have neither material nor time to enter into that 

 qviestion now : but whatever the specimens with an olive-grey tail 

 and minute, if any, white spots to the rectrices may be, there 

 can be no doubt that it is to this form that Gould's term E. 

 heterura has to be restricted. Although Gould, in the introductory
