' 2. Vireolanius pulchellus verticalis, subsp. nov. 



Vireolanius pulchellus, Lawr. Ann. Lye. N. Y. VII, 1862 (Panama). — Baird, 

 Eeview, 1866, 397 (part ; spec's ex Costa Rica). — Zeledon, Cat. Aves de 

 Costa Eica, 1882, No. 99. 



SuBSP. CHAR. — Similar to V. pulchellus (Scl. & Salv.), but with the 

 whole crown bright green, like the back, the blue being confined to the 

 forehead and nape, and the sides of the head decidedly paler green. 



Adult $ (type, No. 34665, U. S. Nat. Mus., Angostura, Costa Eica, 

 June 11, 1864; J. Carmiol) : Entire upper parts, except forehead and 

 nape, bright "parrot" green, the back slightly glossed with verdigris- 

 green, and the outer webs of the primaries with a yellowish- green cast ; 

 forehead and nape light blue, the crown very slightly touched with the 

 same ; entire sides of head, including loral and malar regions, uniform 

 emerald green ; chin and throat pure gamboge-yellow, gradually chang- 

 ing to yellowish-green on jugulum, the whole lower parts being of this 

 color, but more decidedly green laterally and more inclining to yellow 

 on middle of abdomen, anal region, and crissum; lining of wing greenish 

 gamboge yellow, and inner webs of remiges broadly edged with clear 

 primrose-yellow. Maxilla blackish, with pale tomium ; mandible pale 

 (plumbeous in life ?) ; legs and feet brownish (plumbeous in life ?). Total 

 length 6.25, extent 7.75 (Carmiol, MS.); wing, 3.00; tail, 2.10; culmen, 

 .80; bill from nostril, .45 ; depth at base, .27 ; tarsus, .80; middle toe, .55. 



Habitat. — Costa Eica to Panama. 



Examples of this species from Costa Eica and Veragua differ very 

 decidedly from Mexican and Guatemalan specimens in the characters 

 mentioned above. In the northern form, of which there are six exam- 

 ples before me, the entire liileum is blue, only the center of the crown 

 being a little bit tinged with green ; this central green spot, or, rather, 

 indication of a spot, is present in all. In the true V. pulchellus the sides 

 of the head are of a decidedly more intense green color, and there is 

 usually (in five of the six specimens) a more or less distinct indication 

 of a yellowish streak extending fi^om the rictus to beneath the ears. 

 Professor Baird has called attention to this character in his " Eeview 

 of American Birds" (p. 398), and also to the variation in extent of the 

 green on the crown, but, having only one specimen of the southern form 

 for comparison, did not discover the geographical significance of the 

 variations. 



I have not seen Panama examples, but they are presumably similar 

 to those from Veragua; or, perhaps, with still less blue, since an exam- 

 ple from the latter country has no trace whatever of blue on the crown 

 or occiput, while the blue of the forehead is more restricted than in 

 specimens from Angostura, Costa Eica.
