wiiig-coverts marked with well-dctiiied, ]iiile 3elIow tips, and there is also a 

 certain lii;eiiess in the pattern of tlie un<ler parts. E. leiicoi/<istei; however, may 

 be easily distingnished by lacking the white eye-ring (so conspicnons a feature 

 in its ally), by its more heavily striped tiiroat, ashy grey (instead of greenisb 

 yellow) breast, and pnre white (not primrose-yellow) middle of the belly. Be- 

 sides, the upper parts are of a purer, brighter green, and the supraloral streak 

 is mnch less distinct and greyish instead of white. From E. spodiops Berl.* it 

 differs by its mnch larger, uniform black bill, ashy-grey forehead and loral region, 

 ashy grey (not brownish green) ear-coverts, much brighter green back, distinct 

 yellow wing-hands, and mnch paler colour of throat and breast, which, in the 

 Bolivian sjiecies, are dull greyish brown, tlammulated with yellowish. I am 

 indebted to Count Berlepsch for the loan of the type specimen, still uni(|ue in 

 Ids collection.f

Type of i?. albiventiis (Jhapm. — ^Wing 70 ; tail 01 ; bill 11 mm. 



This bird, which I have compared with a considerable series of E. parmrostris 

 (inclnding the types in the Vienna Museum) is a perfectly typical example of that 

 widespread species. In coloration it agrees particularly well with an adult male 

 from Teffe, Rio Solinioens, N. Brazil : upper parts decidedly greenish ; throat and 

 chest clear whitish grey; middle of the breast and abdomen pure white, flanks pale 

 greenish, etc. The feathers of the crown, though slightly longer than those of the 

 forehead, do not form a conspicuons crest, which is invariably the case in the nearly 

 allied, but specitically distinct, E. albkertex Pelz. § The type of E. albieentris 

 is an adult bird, with large, half-concealed white crown-patch. The wings have two 

 well-defined cross-bands, formed by the yellowish-white tips to the median and 

 greater upper wing-coverts.

§ Probably identical with A', cliiriipieiiais Lawr. 1 am unable to discover taugible differenoes between 

 specimens from Chiriqui and Costa Pica on one side and those from Brazil on the other, but the subject 

 requires more careful attention than I can at present bestow upon it.
