518 NOTES ON COSTA RICAN BIRDS CHERRIE. 



throat ochraceous-buify with whitish bases aud narrowly tipped with 

 blackish. Breast olivaceous, becoming grayish or ashy jjosteriorly. 

 Feathers of the center of the breast with large central ochraceous-buff 

 spots surrounded with narrow blackish lines and the feathers edged 

 with olivaceous ; sides smoky gray with olive wash ; center of belly 

 almost pure white, only a few feathers anteriorly with subterminal 

 buffy tips and dusky edges. Under tail-coverts pale buifj-. 



There are no specimens of C. mexicanus in theU. S. National Museum 

 collection and only the type of C.fumosus. 



Campylorhynchus capistratus. 



Two specimens (No. 19, $ , Museo Nacional de Costa Rica, San Mateo, 

 January, 1886, A. Alfaro ; and No. 18, $ , Trojas, February, 1886, A. 

 Alfaro), compared with Mr. Ridgway's type of G. castaneus and six ex- 

 amples of C. capistratus in the U. S. National Museum (two from Sucuya, 

 Nicaragua, one from San Juau del Sur, one from La Palma, and one 

 fromPunta Arenas, Costa Rica) seem to be nearer the former than the 

 latter in the lighter almost uniform chestnut of the back and less con- 

 spicuous spots aud streaks of black and white. No. 18 corresponds 

 very closely in size to castaneus, while No. 18 is larger ; as large as 

 other specimens of capistratus. 



Female examples in the Costa Rica National Museum seem to have 

 the streaking and spotting of the back a little less pronounced than in 

 the males. 



Henicorhina prostheleuca. 



Mr. Zeledon gives in his list H. leucosticta as a Costa Rica bird. How- 

 ever this form probably does not occur in Costa Rica, as the name leucos- 

 ticta is applicable to the black-headed form, which occurs only as far 

 north as Colombia, its place in Central America being taken hy H. pros- 

 theleuca. (See Catalogue Birds Brit. Mus., Vol. yi, pp. 286-288.) 



Henicorhina leucophrys. 



I have before me two skins from the Costa Rica National Museum. 

 No. 2300, S , (Yolcan de Poas, November 23, 1888, A. Alfaro), agrees 

 closely svith descriptions of the species, and also with ten exami^les in 

 the U. S. National Museum, from Mexico, Guatemala, Costa Rica, Yer- 

 agua, and Bogota. There are, however, four of the examples from 

 Costa Rica iu the U. S. National Museum collection which seem to pre- 

 sent some peculiarities or characters which may be variations due to 

 their geographical position. The local variations in the species as com- 

 pared with Costa Rican examples can best be pointed out by making 

 extracts from Mr. Ridgway's manuscript on the subject, which I have 

 before me. The Costa Rica birds "come nearest to the Guatemala 

 specimens, but are somewhat lighter and brighter brown above." Mexi- 

 can specimens " have the entire pileum and hind neck exactly' the same 

 color as the back, except along the lateral margin, where a black line
