Common in the forest, frequenting the tops of the tall

white tufts in front of the eye, as in the closely allied, but 
distinct, species F. cinerascens.

Cape Coast, Gambaga, Salaga, and Krachi. 
Locally distributed and generally observed in pairs. 
Thickets borderiug streams and rivers are its favourite resorts. 
A series of rapid babbling notes are uttered by the male 
bird ; they become persistent just after rain or towards 
evening. At Gambaga we obtained only one specimen — an 
adult male j this differs from our other examples in being 
larger, while the outer tail-feather is bright orange on both 
webs. We shall, however, for the present, refer it to 
C. verticalis. 
144. Cossypha giffardi Hartert. 
Cossypha giffardi Hartert, Nov. Zool. vi. p. 420 (Gam- 
baga) . 
We obtained a single specimen of this species. It does not 
seem to be found at Gambaga, but to the northward along 
the banks of the Upper White Volta River.
