This species occupies chiefly the Subtropical Zone of all three ranges. 

 My single Peruvian specimen, a female from Inca Mine, has the wing-coverts 

 vermiculated with brown and blackish and may therefore be considered as 

 representing this species. Colombian females essentially agree with it but 

 have the outer tail-feathers less broadly tipped with white. I have no 

 males from Peru but our Colombian males agree with three figures in Gould's 

 Monograph (2d ed.) which are said to represent the type.

(1457a) Trogonurus assimilis (Gould). 

 Trogon assimilis Gould, P. Z. S., 1846, p. 67 (Peru). 



Inhabits the Temperate Zone in the Western, Central and Eastern Andes, 

 where it appears to be a zonal representative of T. personatus of the Sub- 

 tropical Zone. Eleven males differ from a large Colombian series of per- 

 sonatus chiefly in the much less pronounced, more broken and, in some cases, 

 almost obsolete white bars on the three outer pairs of rectrices and in having 

 bluer reflections on anterior parts of the crown and breast, and a smaller 

 bill. In the markings of the tail they thus seem to agree with Gould's 

 description of assimilis. Seven females, however, differ from Gould's 

 description of the female of assimilis, and in a like manner from the female 

 oi personatus, in having the wing nearly similar in color as well as in markings 

 to that of the male. The lesser coverts are tinged with brown, but the re- 

 maining coverts and exposed portions of the inner wing-quills are minutely 

 marked with blackish and white, exactly as they are in the male, and all but 

 the three outer quills are conspicuously white at the base. Except in hav- 

 ing somewhat less white in the tail and a smaller bill, these birds in other 

 respects agree with the female of personatus. One of our specimens has the 

 ovaries considerably enlarged. There can, therefore, be no question of its 

 sex. 



In the absence of specimens from Peru I provisionally accept Gould's 

 name for the species. It is true that he described the female of assimilis 

 as having the "coverts and secondaries freckled with yellowish brown in- 

 stead of gray", but it is not improbable that in the absence of exact data, or 

 none at all, he may have had in hand a female of personatus.
