 at Alcolia'-a, on the li?ft bank of the Tocantiiis,t this being the iirst ascertained

The type was obtained by Natterer, November IS, 1829, on the Rio JI.ideira 

 between Crato and Sapnoaiarocca, but ou which side of the river is not stated on the 

 label. Pelzeln (I.e. note 1) also describes the female, which would appear to be 

 very different from that of K. orenocensis Berl., the nearest ally of K. sclateri. 

 Unfortunately it is no longer to be found in the Vienna Museum.]

The two birds have the rufescent edges to the upper wing- coverts rather 

 narrower, and the throat and chest more strongly washed with brownish buff, tiian 

 Peruvian examples with which they otherwise agree. These slight differences may 

 be seasonal or individual. 



Tliis is the first published record of M. JitiriatiUs from Brazil. Natterer had 

 obtained, as long ago as 1829, a single female on the banks of the Rio Madeira, one 

 Jay's journey below Crato, but the species was accidentally omitted in Pelzeln's work.

The specimens jirocured by Mr. Hoffmanns tend to show that most of the 

 characters given in the original description are not constant. The tvpe of 

 P. nattereri is an immature bird, as I satisfied myself by careful re-examination. 



The adult male (No. S92) has the top and sides of the head of the same deep 

 slate-grey as a series of P. griseiceps from British Guiana, Surinam, and the Caura
