buff shaft-lines of the throat and foreneck extend also over the chest, etc. More- 
over, the bill is somewhat flatter, less compressed terminally, and paler in coloar, 
being mostly horny whitish. D. plagosus shares with D. hoffmannsi the shape 
and colour of the bill, but differs widely in coloration. The pileum is clear olive- 
brown with broad, bnffish shaft-stripes, which are, laterally and terminally, 
bordered with blackish; the back, lesser and median wing-coverts show more or 
less distinct dusky cross-lines ; the buff throat-feathers have, on each side, several 
marginal spots of dusky; finally, the chest, breast, and abdomen are much more 
broadly and more regularly banded with blackish.

The typical series, kindly lent by Dr. von Lorenz, differ from a very large suite 
of D. c. certhia, from North Brazil, Cayenne, Guiana, and Venezuela, by lacking 
the dusky cross-bands on the back and upper wing-coverts; the under parts are 
nearly nniform ochreous brown, with but a few obsolete cross-lines in the middle 
of the abdomen; the feathers of the pileum pale olive-brown, indistinctly edged 
with dusky at the tip, while in ). c. certhia they are alternately banded with 
olive-brown and blackish. The bill is dark red, as in D. c. certhia, 
On the Tapajéz a nearly allied form, D. c. ridgwayi Hellm.,* is met with. 
It has lately been rediscovered at Villa Braga and Itaittiiba, on the left bank of 
that river.T]
