112 Graf von Berlepsch on new 
bill for about an inch black ; mtermediate portion of bill and 
base (except round the nostrils) bright ashy blue ; upper sur- 
face of tarsi and toes ashy, with a tinge of light chrome about 
the joints and feet. Stomach crammed with crabs. 
SarcrpIORNIS AFRICANA. African Knob-billed Goose. 
Male, immature, Rustenburg, 25th June. 
The specimen sent is the only one of the kind that I saw 
amongst the Magaliesbergen ; it came down to a shallow pool 
one morning as my brother and I were at breakfast ; and he 
made a successful stalk and floored it. 
[The specimen sent is evidently a young bird in change; it 
has acquired the lustrous adult plumage on the wings, but 
not elsewhere; the feathers of the immature dress on the 
upper surface are a rather deep brown, edged with pale brown ; 
the feathers of the sides of the upper breast and of the thighs 
are pale drab, transversely barred with dark brown ; the 
remainder of the under surface is white, strongly tinged with 
drab, but unspotted, except very slightly on the under tail- 
coverts.—J. H. G.]

1. TANAGRA SCLATERI, sp. nov. (=7". glaucocolpa, Scl., nec 
Tanagra glaucocolpa, Cab.). 
Hab. Orinoco district or Trinidad. 
This bird is somewhat intermediate between 7. cana and 
T. episcopus, having neither the plain blue shoulders of the 
former nor the whitish ones of the latter. The shoulders are 
of a beautiful whitish red or violet-blue, the outer webs of 
the wing-feathers of a more intense blue. The uropygium 
is likewise tinged with violet-blue. This species is more 
beautiful than either 7. cana or T. espicopus; and I have 
seen many specimens, all of the same preparation, coming 
most probably from the eastern part of Venezuela (Orinoco 
district) or Trinidad.
