being uniform dark smoky grey); by having the upper parts dull smoky grey, 
with but a faint brownish tinge (instead of being more or less brightly rafescent 
brown) ; the throat and foreneck much paler, dull buff (instead of bright ochraceons), 
shading into pale greyish buff on flanks ; and by their longer bill and decidedly 
shorter tail, 
A young bird in fluffy plumage, from the upper Rio Negro, belongs most 
certainly also to cineracea, although it is darker, more smoky brown, on the back, 
and more ochreous on the throat. But it is still less brightly coloured than young 
birds of NV. r. rubecula, and shows the long bill as well as the uniform blackish 
grey sides of the head characteristic of V. r. cineracea, 
The range of the two races is, as far as our present knowledge goes, the

This species, of which Mr. Hoffmanns obtained a single adult female on his 
first expedition to the Rio Madeira in 1906, is somewhat like NV. r. rubecula, 
having the upper parts warm brown, bat may be distinguished by its much smaller 
size (wing 62; tail 534 mm.); deep ochraceous buff (instead of white or pale 
buffy) frontal band, lores, and chin ; duller, more greyish fulvous, throat and 
foreneck, which, however, are much deeper in tint than in W. r, cineracea, etc. 
Like the latter race, it lacks the whitish patch below the eye, and has the flanks 
* Sclater (Monogr. Jacamars and Puff Birds p. 134) also records it from the Lower Amazons, but 
I have not been able to ascertain on what authority. Wallace certainly did not obtain specimens 
anywhere on the Lower Amazons (cf. P. Z. 8. Lond. 1867. pp. 566-96). It is also to be remembered that 
none of the more recent travellers (Robert, Hoffmanns, Snethlage) met with W. x. rwbecula in the Para 
district,
