uniform with the back, and, like the tail, transversely barred with 

 black ; the barring on the lesser iipjier wing-coverts * obsolete, ia 

 the rest of the wing and on the tail distinct, being ^-4'" broad on 

 the first tail-feathers and as much as 1'" on the outer ones ; a 

 superciliary streak produced to the nape, lores, sides of head, and 

 throat white, the feathers of the ear-coverts obscurely edged ; 

 remainder of the under surface and under wing-coverts ferruginous, 

 the middle of the breast albescent ; ujjper mandible horny, its 

 cutting-edges and the lower mandible pale. Total length 5 inches, 

 culmen 0-7, wing 2-25, tail 2 {Pelzeln). 



Pelzeln's Wren was discovered by the late Johann Natterer in 

 the interior of Brazil at Matagrosso and on the Guapore river. It 

 is described by Herr von Pclzeln as being very close to T. IcHcotis, 

 but smaller, with the upper surface greyish olive-brown, with very 

 little admixture of reddish, and the under surface reddish buff, with 

 the exception of the centre of the breast being white. The species 

 is not represented in the British Museum, and it appears to be one 

 of the numerous races of T. leucotis the exact definition of which 

 has yet to be thoroi;ghly worked out, the material at my disposal 

 not being sufficient.
