outer web forming a conspicuous transversal band; quills brown, exterior webs edged 
narrowly with olive-yellow, shading into cream-colour at the tips of the tertiaries, inner 
webs broadly edged with pale yellowish white; tail olive-brown; chin whitish; under 
surface pale glistening yellow; flanks and under tail-coverts olive-yellow, mottled with 
black; on the sides of the breast there are numerous small oval black spots; irides red; 
bill plumbeous; legs and feet black. Wing 3"-2, tail 2"-3. 
Female.— The female has the colours of the top of the head and occiput duller ; the 
whole of the upper plumage is interspersed with white ; the wing-coverts are edged with 
dirty yellowish white ; the whole of the under surface is covered with large black spots, 
except on the centre of the abdomen. 
The young bird has the same plumage as the female, except that the throat is not 
spotted. 
Hah. Eastern Peru (Sclater) ; Cayenne (Pollen). 
The species was one of the first known of the whole family, having been mentioned as 
long ago as 1760. As the " Bucco niger " of Miiller is clearly this species, his name, though 
niappropriate, must stand. Owing to the great diff^erence of colouring existing between 
the male, female, and young, the two latter have by several authors been given separate 
specific names; further research, however, has now quite cleared up the point. Des Murs, 
in the 'Eevue Zoologique' for 1849, gave a very exhaustive account of the colouring of 
this species at the different stages of maturity ; it is a remarkable fact that the American 
members of this family are the only ones in which the sexes difi'er. 
Ca])ito niger, to judge from the number of specimens in this country, is by no means a 
rare bird ; of its habits and nidification nothing need be said, since, as far as we know, they 
in no way difier from other species. 
The figures in the Plate are taken from specimens in our own collection.
