N.B.—I have not seen specimens from Eastern Ecuador. In Pern a nearly 
allied, but sufficiently distinct, form is met with. There are three examples of it 
in the Paris Museum, obtained by Comte de Castelnau. It will shortly be described 
in another connection.

“Tris pale yellow, feet grey, bill blackish grey.” 
Count Berlepsch has pointed out that the £. zosterops minor of Snethlage 
is quite distinct from the trae EH. zosterops Pelz., and accordingly proposed the 
new generic term Snethlagea for it.* Besides the above-mentioned specimens I 
have examined, in the British Museum, the adult male from Borba, obtained by 
Natterer February 12, 1830, and described by Mr. PL. Sclater s.n. E. zosterops,+ 
and found them all to belong to the present species. S. minor, though resembling 
Euscarthmus zosterops in general coloration, differs by the singular shape of the 
nostrils, which are very large, nearly circular, and quite exposed, and by the strongly 
rounded tail, in which the central rectrices are lougest, being about 5 mm. longer 
than the outermost. In E. zosterops, on the other hand, the nostrils are situated 
in an operculate fossa, with the narrow, slit-like nasal opening near its lower edge ; 
the tail is also strongly rounded, but at the same time distinctly emarginate, the 
central rectrices being slightly shorter than the submedian ones. 
Adult males of S. minor have the rictal bristles exceedingly well developed, 
reaching nearly to the tip of the bill. In coloration the specimens from the
