the back, while in the single female the greater series have more yellowish 

 margins, which, however, do not form a distiact wing-baud. The supra-loral 

 stripe is dull white, as in E. s. .zonterops, not rusty buff, as in 7?. s. Johanuis. 

 From JJ. s. zosterops, of N.W. Brazil (Upper Kio Negro) aud East Ecuailor 

 (.Santiago Riverj the new form may be distinguished by the dark brown (instead 

 of ashy) ear-coverts, considerably deeper yellow belly with more greenish si;ffn- 

 sion on the foreneck, by lacking the pale yellow transverse bands on the wing- 

 coverts, and by the absence of the cinereous forehead. 



The range of the races of E. striaticollis is thus as follows : 



(a) E. striaticollis striaticollis (Lafr.). Central and Eastern Brazil, from Bahia 

 west to the Rio Madeira and its tributaries, north to the Amazons (Santarem). 



{!)) E. striaticollis johannis Snethl. West Brazil : npper Rio Purus. 



((') E. striaticollis amazo/iicus Hellm. Eastern Peru: Moyobamba, Pebas. 



(d) E. striaticollis zosterops Pelz. North-west Brazil : upper Rio Negro 

 (S. Carlos, Marabitanas) and Eastern Ecuador (Rio Santiago). 



The Munich Museum has lately received, through Mr. W. F. H. Rosenberg, of 

 London, a new species from Sonth Peru, which may be called 



Euscarthmus leucogaster n. sp. 



A(/>ilt.—l]pi)eT parts light olive greeu (somewhat brighter aud purer than 

 in E. s. zosterops) ; the feathers of the crown with dusky centres aud distinctly 

 elongated so as to form a slight crest ; the edge of the forehead washed with 

 ashy, as in E. s. zosterops ; lores greyish white ; a narrow rim round the eye, 

 cheeks aud ear-coverts dull ashy grey, the latter faintly tinged with greenish 

 in their posterior portion. Lesser upper wing-coverts bright olive green like 

 the back ; median and greater coverts blackish, with pale yellow apical spots, 

 forming two well-defined transverse bands across the wing ; remiges blackish, 

 conspicuously, though narrowly, edged with yellowish green, inner secondaries 

 (tertials) more broadly edged with yellowish white on the outer web ; rectrices 

 blackish, with yellowish-green outer margins. Throat white, distinctly streaked 

 with dusky grey (the median portion of the feathers being dark, the edges white) ; 

 foreneck and chest pale ashy grey, flammulated with whitish ; middle of the 

 breast and abdomen jiure white, the inner flanks faintly tinged with light 

 greenish ; under tail-coverts yellowish white ; axillaries, under wing-coverts aud 

 edge of the wing bright yellow, qnill-lining whitish. " Iris grey, feet dark slate, 

 bill black."

Ohs. — A second specimen, ? ad. (same date and locality) in Count Seilern's 

 collection difters from the male described above by smaller size, more conspicuous 

 supra-loral streak, less distinct striping of the throat, and more whitish (less greyish) 

 foreneck and chest. In all other respects it exactly resembles the type. 



This new Euscarthmus agrees in structure (form of bill, shape of tail and 

 wing) with the members of the E. striaticollis group. As far as coloration is 

 concerned, it most resembles the North Brazilian E. s. zosterops, having the 

 forehead cinereous, the cheeks and ear-coverts ashy gre}', the median aud greater
