Having always snspectcd tbat tbere mnst be some mistake about Lcptopogon 

 tristis, I was not in tbe least surprised to find tbat tbis species bad notbing what- 

 ever to do with Leptopogoii, bnt was in every respect a typical member of tbe genus 

 Phylloscartes. 



The type is an immature bird with some of the fluffy feathers of the juvenile 

 plumage still retained, especially on the nape and lower tail-coverts, but otherwise 

 it agrees in structure and coloration with my series from Tucuman. 



When lately in Paris I was so fortunate as to discover among tbe skins in the 

 collection of tbe Museum d'Histoire Naturelle tbe type of Mnscicapa an(jnstirostris 

 Lafr. & D'Orb., a species which bad never been identified, although the original 

 description was sufficiently clear, tbe shape of the bill and tbe characteristic markings 

 of the wings being very accurately described. The type, an adult bird, is exactly like 

 the specimens from Tncnman. The S ad. from Chachapoyas does not differ either. 



PliijUoscartcs ventralis anipistirostris (Lafr. & D'Orb.), as tbis form ought to 

 be called, is practically identical in all structural details with a large series of true 

 P. V. ventralis of Eastern Brazil, and differs but slightly in coloration. The upper 

 parts are of a duller, paler, more greyish green ; tbe lower ones rather paler yellow ; 

 the throat more mixed with whitish ; the yellow wing-bands as a rule a little 

 broader, and the forehead always washed with greyish. Thus tbere are two very 

 nearly allied forms recognisable, the range of which is as follows : 



1. Phylloscartes ventralis -centralis (Temm.). Wood region oi S.E. Brazil: from 



S. Paulo to Rio grande do Sul. 



2. Phylloscartes ventralis angustirostris (Lafr. & D'Orb.) N. W. Argentina : 



Tucumiiu ; Bolivia : Yungas of La Paz (D'Orbignj'), Simacn (Buckley) ; 



iV. Peru : Chachapoyas (0. T. Baron). 



N.B. — Tbe bird mentioned by Lafresnaye and D'Orbigny s. n. Muscicapa 

 ventralis (p. c. p. 53) is Capsiempis Jiateola (Lcbt.). There are two skins from 

 Guarayos in the Paris Museum, fully agreeing witli Bahia specimens. 



Specimen h of Leptopogon tristis (^Cat. Birds xiv. p. 118) is widely different, 

 and represents a new species of Pogonotriccus, which will be described by 

 Count Berlepscb.

Tbis " sj>ecie8 " has nothing to do with LepAopogon, and is, indeed, very 

 different from all members of tbat genus, but on comparing it with a series of 

 P. ophthalmicus (9) from Central and North Peru, Ecuador and Bogotsl, I fail to see 

 any dillerence. The types are both slightly immature, as manifested by their short 

 and stout bills. Adult speciuiens have rather longer and more slender bills. 



No. 1 agrees perfeitly with a ? from Pichincha, Ecuador, in shaj)e and size of 

 till' bill, while No. 2 has a rather broader and stouter bill. Three other examples
