SENEGAL TOURACO. 
and explicit than the above quotations. Although 
not in general friendly to geographic names, there 
are some instances like the present where they 
may he applied with peculiar advantage, particu- 
larly if the principle had been extended to the 
other species. The true ( Corythaix ) Versa of 
Yieillot is peculiar to Southern Africa ; the blue 
crested species, mentioned by Buffon, has only been 
found in Abyssinia, while this seems to be equally 
restricted to Senegal, or at least to the Western 
Coast of tropical Africa. 
The general size of the Senegal Touraco is about 
equal to that of the Cape species ; like that, also, 
the fore part of the crest, immediately before the 
eye, in the dead bird, is compressed vertically ; the 
remaining portion, however, seems to be depressed 
horizontally as in the generality of crested birds. 
The bill in the dead bird is blackish purple in the 
middle, but bright crimson along the edge of the 
culmen and within the margin of the sides, the tips 
and serratures of both mandibles being blackish ; it 
is possible, however, that in the living bird the 
whole may be red, although we- think this is very 
doubtful. Tire orbits are crimson, naked, and tu- 
berculated ; the white stripe before the eye extends 
to about one-third the length of the upper eye-lid, 
■while the black stripe beneath it reaches as far 
towards the ears as the end of the naked red orbits. 
But there is no vistige whatever of a second white 
stripe. A uniform grass green, but without any gloss, 
spreads over the whole of the head, heck, wing-
