Adult male. Differs from F. m. melanogastra, Pelz., from 

 Goyaz (two specimens examinedj including the type) in its 

 slightly smaller size, somewhat more slender bill, and in 

 having the flanks white (instead of sooty-black as in the 

 typical race). Moreover, on the sides of the neck there is a 

 distinct white stripe, more or less confluent with the white 

 of the flanks and separating the colour of the back from the 

 black underparts, and the white streak along the outer web of 

 the third rectrix is altogether absent. Culmen 13 mm. ; 

 wing 51 ; tail 53. 



Adult female. Similar in coloration to that of F. m. melano- 

 gastra (four specimens examined); but rather smaller and 

 with the white markings on the tail-feathers more restricted. 

 Culmen 15 mm. ; wing 51 -, tail 54-55.

Dendrocolaptes hoffmannsi, sp. n. 



Adult male. Nearest to D. c. certhia (Bodd.), from the 

 Guianas and Venezuela, but the crown and occiput are washed 

 with cinnamomeous, and the back as well as the upper wing- 

 coverts are uniform olivaceous-brown, without any dusky 

 cross-bands ; the feathers of the throat and fore-neck, 

 instead of being cross- banded as in D. c. certhia and D. c. 

 radiolatus, Scl. & Salv., of Upper Amazonia and the Rio 

 Negro, show a strongly defined longitudinal central streak 

 of buff, bordered laterally by a number of rather indistinct 

 minute dusky dots. Bill much more slender, compressed 

 and blackish; under mandible paler (not dark reddish). 

 Wing decidedly longer. Culmen 36 mm. ; wing 140 ; tail 120.
