 Ilab. iHthiuui) of Panama. 



Male : Second quill botwoe-n 6th and Tth ; 4th and 5th longest. 

 Color above dark browiiiish olive, deepest on the head; beneath show- 

 ing a considerably paler shade of the same, but darkest on the wides ; 

 throat similar, but with a grayish tinge, the centres of the feathers 

 obsoletely darker. Region about the vent and under tail coverts 

 pure white. Inner wing coverts, axillars, and inner edges of the 

 quills cinnamon rufous. Greater coverts with a spot of cinnamon 

 at tho end (an indication of immaturity ?). Bill and legs uniform 

 brown. 



Length, 8.10; wing, 4.60; tail, 3.80; bill from gape, 1.15, from 

 .nostril, .58; tarsus, 1.17 ; middle toe and claw, 1.15. 



I owe the opportunity of examining this species to tho kindness 

 of Mr. Lawrence, the description being taken from his type speci- 

 men No. 12, collected by Mr. M'Leaunan in 1862. Tho peculiar 

 dark lines crossing the feathers on the back, described by Mr. Law- 

 rence, are purely optical in character, being similar to tho watering 

 of silks, etc. The under parts, too, are quite uniform, the edges of 

 the feathers being possibly a little ferruginous. 



This species may be the female of one of the black species as 

 suggested by Dr. Sclater, in a letter to Mr, Lawrence ; but I am 

 unable to assign it to any of those described, and the bird is marked 

 as a male by Mr. M'Leaunan.

In highly plumaged specimens from the east the feathers of the 

 inter-scapular region are frequently, even generally, tinged with 

 blackish in their centres, passing gradually into ash on the edges, 

 and the blaclr of the head ceases to be sharply defined. There is also 

 usually a well defined whitish tip, half au inch long, to the outer tail 

 feathers.
