96 Mr. D. A. Bannerman on rare Birds [Ibis, 
Museum. There are now three birds in the collection 
obtained by Mr. Bates on the River Ja. No. 4220 has 
already been recorded by Mr. Bates (l. c.). It has a 
remarkably mottled appearance, due to the feathers of the 
crown, mantle, greater and lesser coverts, primaries and 
secondaries, upper tail-coverts and tail being broadly tipped 
with white. The adult bird is uniformly coloured blackish 
brown on the entire upper parts. As Mr. Bates has already 
remarked, the bird, though in such spotted plumage, is not 
very young—the wing measures 220 mm.—and had evidently 
itself caught the numerous insects which were contained in 
its stomach. 
Pachycoccyx validus ranges from British East Africa 
south to Nyasaland, across the Belgian Congo to Came¬ 
roon, Gaboon, and northern Angola. . It has also been 
obtained in two widely separated localities in the late 
German Togoland according to Reichenow. 
Chrysococcyx flavigularis. 
Chrysococcyx flavigularis Shelley, P. Z. S. 1879, p. 679, 
pi. 50—Type locality: Gold Coast; Sharpe, Ibis, 1907, 
p. 437 ; Bates, Ibis, 1911, p. 502. 
Mr. Bates’s collection contains four more examples of 
this extremely rare Golden Cuckoo, all obtained during the 
month of December in 1908, 1913, and 1914. Two are 
females, but the sex of the other two has been ascertained 
as males. In plumage they closely resemble the female, and 
must therefore be young birds, as the adult male is a very 
distinct-looking bird. There is no indication of the yellow 
throat in either specimen, the entire under surface being 
narrowly barred as in the female.
