CAMPEPHAGA 201 
This species appears to take the place of the more richly 
coloured L. lobatus in Cameroon, whence it probably extends 
to Gaboon and Angola. Du Chaillu obtained a specimen at 
the Camma River in the former country, which, judging from 
Cassin’s remarks (Proc. Acad. Philad., 1859, p. 52), is a female, 
while Hartlaub states that there is another specimen in the 
Leyden Museum. 
Genus II. CAMPHPHAGA. 
Bill black, rather short and flattened, broad at the gape and compressed 
beyond the nostrils. Sexes very dissimilar in colouring, the adult males 
being black, with a distinct gloss, and with or without a yellow or red 
patch on the wing-coverts, while the plumage of the females and young 
males consists of a mixture of olive, yellow and white with no gloss, 
generally with black bars more or less in evidence. 
Type. 
Campephaga, Vieill. Analyse, p. 39 (1816) . . . . C. nigra. 
Lanicterus, Less. Ann. Se. Nat. (2) ix. p. 169 (1838). C. xanthornoides. 
Cyrtes, Reichenb. Avium. Syst. pl. 68, fig. 11 (1850) . C. phenicea. 
The genus is confined to Tropical and South Africa, for I look upon the 
Asiatic genus Volvicivora, Hodgs., as distinct. 
Ihave divided the genus into eight species. The range of C. hartlaubi 
is the same as that of C. nigra and its only distinguishing marks, the lemon 
yellow on the wing-coverts of adult males, is variable in amount, two facts 
which tend to prove it to be a variation only. In like manner, C. canthornoides 
occurs only where C. phanicea is found and an intermediate form is known 
in the type of C. ignita.
