N.B. — I have not seen specimens from Eastern Ecuador. In Peru a nearly 

 allied, but sufficiently distinct, form is met with. There are three examples of it 

 in the Paris Museum, obtained by Gomte de Castelnau. It will shortly be described 

 in anotlier connection.

Count Berlepsch has pointed out that the E. zosterops minor of Snethlage 

 is quite distinct from the true E. zosterops Pelz., and accordingly proposed the 

 new generic terra Snetldagea 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. P. L. Sclater s.n. E. zosterops,f 

 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 longest, being about 5 mm. longer 

 tiian the outermost. In E. zo.'iterops, 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
