SENEGAL TOURACO. 22? 



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 (Coryihaix) Per so, of 

 Vieillot 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. The 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, 

 out 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, neck, wing-
