SENEGAL TOUHACO. 
three species*, Linnasus confounded them under 
one. More recently the Cape Touraco has been 
separated as distinct, on account of the white mar- 
gin of its crest ; and that which Bufion describes as 
having this part purple, has also received a specific 
name. There yet remains, however, at least two 
other species, both having green crests, but one is 
with and the other without a reddish margin. These 
two have not only been confounded by Wagler, but 
the whole genus again thrown into confusion by his 
unwarrantable attempt to substitute his own new 
names, not only for the species but for the genus. 
In this state of things, it seems best to retain 
the name of Buffonii, first given by Yieillot to 
the species, so well recorded by Edwards. That 
most accurate writer-, in describing his Touraco, 
says, that “ the very tips of the feathers on the crest 
are red,” and that “ under the eye is a white line 
which extends a little further back than the black 
one, but does not come forward so near the billt.” 
Neither of these characters appear in the Senegal 
species. In three specimens, now before us, there is 
no red whatever on the margins of the crest, neither 
is there any white stripe beneath the eye. The 
authors of the Illustrations of Ornithology, who 
seem to consider the Senegal species the same as 
that described by Edwards, have doubtless been led 
to do so by the confusion of the synonyms given by 
Wagler and Yieillot, for nothing can be more clear
