extends northwards into Eastern Ecuador, where Buckley obtained specimens at Sarayacu on 

 the Bobanasa, and southward into Bolivia, where the late Prof. Behn of Kiel procured specimens 

 in the provinces of Chiquitos and Santa Cruz. 



Natterer collected a series of no less than eighteen examples of this Nunbird during his 

 journey from South-eastern Brazil to Para. Herr von Pelzeln gives us the following list of the 

 localities : — Goyabeira and Taquaral, in the province of Goiaz ; Cuyaba ; Villa Maria on the 

 Upper Paraguay, and Caicara in the same district; Borba on the Madeira; Barcellos on the 

 Eio Negro ; and Cajutuba, near Para. About the last-named place there seems to have been 

 some doubt ; but the species unquestionably occurs in Lower Amazonia, as I have a skin obtained 

 by Mr. Wallace on the Tocantins river in September 1848. 



Herr v. Pelzeln describes a very young Nunbird, obtained by Natterer at CaiQara, as of a 

 dirty slate-colour, here and there passing almost imperceptibly into rufous; the throat much 

 mixed with rusty red. There is a specimen in just such a plumage in the Jardin des Plantes 

 at Paris, procured on the Upper Amazons by Castelnau and Deville. Herr von Pelzeln more- 

 over gives us the following notes of Natterer upon this bird, taken at Goyabeira in the month 

 of July. " Found in high trees in the dense forest, but not on the tops ; sits quiet until it sees 

 an insect, which it captures flying. There were six in a flock, of which I shot four. In the 

 stomach I found grasshoppers and beetles. They feed also rather near the ground. They have 

 a loud piping cry." 



I add a list of the specimens of M. nigrifrons in my collection and that of Messrs. Salvin
