bnff shaft-lines of the throat and fnreneck extend also over the chest, etc. More- 

 over, the bill is somewhat fliitter, less compressed terminally, and paler iu colour, 

 being mostly horny whitish. I>. playosy.i shares with D. Iiojfmaniisi the shape 

 and colour of the bill, liut dift'ers widely in coloration. The pilenra is clear olive- 

 brown with broad, bntfisli shaft-stripes, which are, laterally and terminally, 

 bordered with blackish ; the back, lesser and median wing-coverts show more or 

 less distinct dnsky cross-lines ; the bnff throat-feathers have, on each side, several 

 marginal s])ots of dnsky ; 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 dnsky cross-bands on the back and upper wing-coverts ; the under parts are 

 nearly uniform ochreons lirown, 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 D. c. certliid they are alternately banded with 

 olive-brown and blackish. The bill is dark red, as in I), r. certhia. 



On the Tapajoz a nearly allied form, T). c. ridyicaiji Hellm.,* is met with. 

 It has lately been rediscovered at Villa Braga and Itaitnba, on the left bank of 

 that river. t]
