portant point, however, is that the bare patch on the sides of 
the tace extends some way behind the eye, and this is clearly 
shown in the figure in Du Bus’s work *. 
In an adult male example from Prince’s Island, obtained 
by Leonardo Fea at Prince’s Island in 1901, kindly lent to 
me by Dr. Gestro from the Genoa Museum, the bare skin 
extends a very little way behind the eye—an important fact 
which I omitted to note in 1914, when discussing this par- | 
ticular specimen. RT OE) 
It appears to me, therefore, that:,as Reichenow has appa~ 
rently an adult bird from Cameroon whieh he has called 
eupreipennis, and which he distinguishes from the Prince’s 
Isiand bird by having the feathers on the head and neck 
darker—a distinguishing character which my bird from 
Kfulen bears out,—that he has merely renamed Lampribis 
olivacea Du Bus, from the coast of Guinea, and that his 
Lampribis cupreipennis must become a synonym of Lam- 
pribis olivacea, and that the name Lampribis olivacea must be 
restricted to birds from the mainland of Africa—terra 
typica: ‘Coast of Guinea,”—no recent specimens. 
It is certain that Reichenow’s description. of L. cuprei- 
pennis agrees well with the bird obtained by. Mr. Bates at 
Hfulen (close to the type-locality of cupreipennis) and that 
the Efulen bird agrees exactly with the plate of Jbzs olt- 
vacea in Du Bus’s first work (Buil. Acad. Roy. Sci.), and 
also with the plate of Ibis olivacea in the ‘ Hsquisses Orni- 
thologiques,’ except that the bare skin is there coloured red, 
whereas it is coloured black in the first-mentioned figure. 
The Prince’s Island bird is, moreover, considerably larger 
than the bird from the mainland, markedly so in the bill 
and wing. We are then faced with the fact that the Ibis 
from Prince’s Island is left without a name, and I propose 
to name it
