Adult male {tjYiQ, No. 112255, Segovia Kiver, Honduras, June 17, 

 1887; Charles II. Townsend): Top of bead (except occiput) plain, dark 

 brownish gray, or dull slate-color, becoming somewhat lighter on lores, 

 decidedly lighter or dull ash-gray on auriculars and cheeks ; occiput 

 and entire neck chestnut-rufous; back, scajHilars, and wings olive- 

 brown, the exterior scapulars and wing-coverts barred witli white; ruuip 

 brownish dusky, narrowly barred with brownish white; upper tail-cov- 

 erts and tail plain dark brown. Chin and upper throat dull white, 

 changing gradually along median portion of fore-neck, chest, and breast 

 to pale ash-gray, this color deepening on sides of neck, chest, and breast 

 into deeper ash-gray ; belly i^lain white; sides, flanks, anal region, and 

 under tail-coverts sharply barred with white and black, the bars of the 

 two colors about equal in width and averaging about .08 wide ; axillars 

 similarly barred, but with white bars decidedly narrower than the dark 

 ones; under wing-coverts indistinctly barred with grayish brown and 

 whitish. Bill olive-greenish and the upper mandible chiefly blackish ; 

 legs and feet (in dried skin) pale yellowish brown. Length (skin) 5.30, 

 wing 2.85, tail 1.25, culmeu .03, bill from, rictus .80, tarsus 1.05, middle 

 toe 1.12, with claw 1.38. 



I have not been able to compare this bird with a specimen of P. exilis 

 (Temm.), the habitat of which is given by Messrs. Sclater and Salviu 

 as Cayenne, Peruvian Amazons, Para, and Trinidad; but the measure- 

 ments given by the above mentioned authors {cf. P. Z. S., 1808, p. 457) 

 indicate for that species decidedly smaller bill and feet, the difference 

 being api)areutly too great to be explained by individual variation. 

 Comi^arative measurements are as follows:
