215. CicHLADUSA RUFICAUDA. Red-tailed Chat-Thrush. 
Originally described by M. Jules Verreaux from the Gaboon, the 
present bird is included in this work on account of its occurrence in 
Benguela. A single specimen is recorded by Professor Barboza du 
Bocage as having been obtained by Senor Anchieta in the latter 
country, where it is called by the natives “ Kitoni.” Never having 
seen a specimen of this bird, we translate the following description 
from Dr. Hartlaub’s “ Birds of Western Africa.” 
Above pale brownish-red ; the back more ashy ; head and wings 
browner; rump and tail bright red, the shafts of the tail feathers 
red; primaries dusky ; under wing-coverts isabelline colour; sides 
of the head and neck, eyebrow, breast, and sides of the abdomen 
ashy; middle of the abdomen, chin, and throat pale buff; under 
tail-coverts pale rufous; bill black; feet dusky. Total length, 
7 inches; bill, 7” ; wing, 3” 3’”; tail, 24”; tarsus, 11”; middle toe, 
with claw, 84’”. 
216. Pryarornis pLumosus, Sharpe.* | Sooty-brown Chat-Thrush. 
The British Museum contains the unique type of this curious bird, 
for which no name appears to have been proposed, and it is here 
designated as belonging to an undescribed genus and species. The 
single example yet known was contained in a collection from the 
* rivapoc, sordidus; 6prig, avis.
