This bird, evidently a very old female, differs from an adult male procured near 
Para, in November 1834, by Natterer (one of the types of A/. macrorhynchus Pelz.* ) 
in the following particulars: the top and sides of the head are black (instead of 
slate-grey like the back) ; the feathers of the sides of the body are uniform white, 
showing no trace of the dusky shaft-lines so conspicuous a feature In the Para 
specimen; the light cross-bands of the tail are greyish ash (instead of sepia-brown) ; 
the lower mandible is black, not yellow. Otherwise the two examples are very 
similar, except that the Allianca bird, being a female, is decidedly larger.{ In 
both the lower surface, from the chin to the under tail-coverts, is uniform white. 
M. mirandollei is new to the fauna of the Rio Madeira, but it had been obtained 
at Chyavetas, in Northern Pera, by B. Bartlett,t and in various localities in North 
Brazil by J. Natterer.
