2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



Distribution. — Known only from the type locality. 



Subspecific characters. — In general resembles typical pelzelni, but 

 upperparts browner, less greenish ; crest more blackish ; outer 

 edges of wing feathers including coverts and edges of tail feathers 

 rusty chestnut instead of olive greenish; bill larger and entirely 

 black. 



Description.— -Top of head including the well developed crest of 

 broad round-tipped feathers dusky slate, but forehead paler, more 

 olivaceous ; back entirely dull olivaceous brown, becoming more 

 greenish olivaceous in some specimens ; sides of head and neck 

 similar to back but paler ; wing and tail feathers dusky slate color 

 edged with dark rusty chestnut (lighter rusty on wings), with no 

 trace of olivaceous ; chin, throat and abdomen pale greenish yellow, 

 shading laterally into dull olivaceous or brownish olivaceous, becom- 

 ing browner on flanks ; a poorly defined band of dull olivaceous 

 extends across breast separating yellow throat area from that of 

 abdomen ; lower thighs and under tail coverts dark rusty or rusty 

 brownish ; bill entirely black ; feet and tarsus dull horn color. 



Comparative measurements of a co-type of P. pelzelni from 

 Marhay, East Ecuador, in collection of Count von Berlepsch, and of 

 the type of P. p. berlepschi. 



P. p. pelzelni (adult male) : wing, 56 millimeters; tail, 44.7; cul- 

 men, 10.5 ; tarsus, 19.5. 



P. p. berlepschi (adult male): wing, 57 millimeters; tail, 45; 

 culmen, 12; tarsus, 20.7. 



Remarks — I am indebted to Count Hans von Berlepsch for his 

 kindness in comparing the type of the present well marked sub- 

 species with a co-type of P. pelzelni in his collection, and for the 

 accompanying statement of the differences and measurements of the 

 two forms. As a slight recognition of his work in tropical American 

 ornithology I take pleasure in naming this bird in honor of Count 

 von Berlepsch. 



Goldman collected four specimens of this bird near the summit of 

 Mount Pirri which agree in the characters set forth above, but 

 one specimen is much more rusty brown, both above and below, 

 than the others, perhaps a mark of immaturity, and one has the 

 back distinctly more olive greenish ; but all agree in the black bill and 

 rusty chestnut margins to wing and tail feathers, including the wing 

 coverts. 



In general appearance this species resembles a Myiobins. The 

 crest, which is well marked, is made up of rather long and broad 

 feathers, rounded at the tip.
