Setophaga aurautiaca. 



A single specimen from the collection of the Costa JRica National 

 Museum is bright orange yellow below, decidedly brighter than any of 

 the examples in the U. S. National Museum collection, including the 

 type. 



Vireo pallens. 



A single example of this rare vireo taken at Punta Arenas, Costa 

 Eica, (No. 2940, 9 , Museo Nacional de Costa Kica, March (5, 1889, Alfaro 

 and Cherrie), agrees very closely with one of Mr. Salvin's types of the 

 species (that described by Professor Baird in his Review), No. 33G01, 

 U. S. National Museum. The upper parts are slightly brighter dull 

 grayish olive, the edges of the quills and tail-feathers are also slightly 

 brighter, the two white bands on the wings are well developed. Beneath 

 there is more of a buffy shade than in the type, and the tibije are duskj^ 

 blackish, not " ashy.'' The specimen is not in very good condition, 

 and it is hard to make out the characters about the head ; but there is 

 a whitish line from the bill and extending above the eye ; the lores are 

 dusky, while the front edge of the eyelids is black ; the auriculars are 

 darker, more dusky than in the type; the bill is horn color, the feet 

 dusky, and the iris white. It measures length (skin), 4,20 ; wing, 2.22; 

 tail, 2.06; gonys, 0.28; depth of bill at base, 0.16; width at nostrils, 

 0.18 ; tarsus, 0.76 ; middle toe and claw, 0.58 (the tip of the upper 

 mandible is broken away). The specimen was taken among the man- 

 groves back of the town, probably in about the same sort of locality as 

 the type.
