'icumnus flavotinctus sp. uov. 



Sp. Char. — Similar to P. olivaceus Lafr., from Colombia, but brighter 

 Mivaceous above, lower parts more yellowish, with chest deeper olivace- 

 ous and streaks of sides, etc., broader and less distinct; male with crown 

 decked with dull light orange, instead of deep orpiment-orange, the spots 

 iiuch smaller and covering a more restricted area; female with white 

 specks on hinder crown and occiput much smaller as well as sparser. 

 ; Hab.— Costa Rica (Pacific side) to Panama. 



I Adult male (type, No. 11 6593, Pozo Azul, Costa Rica, September 6, 1886 ; 

 Jose C. Zeledon). — Pileum dull black, the middle of the crown flecked 

 with light dull orange, and occiput minutely dotted with white; hind 

 neck, upper back, anterior scapulars, and wing-coverts plain dull olive, 

 passing into brighter olive on lower back, posterior scapulars, rump, and 

 ledges of middle and greater wing-coverts, the upper tail-coverts light 

 buffy olivaceous; alula, primary- coverts, and remiges dull blackish 

 dusky, the secondaries broadly margined with bright yellowish olive, 

 laud primaries narrowly edged with dull olive; tail dull black, the middle 

 pair of rectrices with inner web chiefly dull light buffy and two outer 

 pairs broadly tipped with the same, the outer web with an indistinct 

 terminal spot of dusky, and a pale yellowish margin to outer web. Lores 

 'and malar region dull whitish, the latter tinged with pale olive and 

 squamated with dusky; auriculars plain olive-brownish; chin and throat

Adult female (No. 116594, same locality, etc.).— Similar to the male, but 



without orange markings on the crown, white specks on occiput sparser 



and very minute, and the general coloration paler and duller, especially 



| the lower parts. Length (skin), 3.30; wing, 2.10; tail, 2.2o; culmen, 



.50 ; tarsus, .52. 



Although this bird may prove to be merely a geographical race ot 

 the Colombian 1\ olivaceus Lafr., a male from Panama (No. 53959, J.

 oran-e flecks on the crown and deep olivaceous coloration strong 

 washed with yellowish on the under parts of Costa Rican specimens, 

 as contrasted with the deep orange-red crown-markings and dull oliva- 

 ceous coloration, without distinct yellow tinge beneath, of the Bogota 

 i bird, of which there are four adult males now before me. It should oe 

 I remarked, however, that this Panama specimen, compared with the
