Campothera teniolema barake, subsp. nov. 
2. Very like C. teniolema from East Africa, but. differs 
as follows :— 
The whole of the underside from chin to vent with a 
clearer white ground-colour without any greenish-yellow 
wash on throat and upper breast, and barred more decidedly 
with blackish olive-green. The spotting of the head not so 
large, and the black cap more extensive. The tooth-markings 
on the inner webs of primaries and secondaries not so washed 
with yellow, and the spots of the outer webs of the primaries 
small and whiter. 
Size smaller on the whole. 
Type in Tring Museum. 2 ad., no. 3836, Baraka, N.W. 
Tanganyika. Grauer Coll. 
Mr. J. D. La Tovcue sent the following communication 
on the Red-bellied Rock-Thrushes of China :— ) 
The variation in size of the Red-bellied Rock-thrushes of 
the Far Hast has not hitherto been paid much attention to, 
although I believe that Dr. Sharpe was at one time inclined 
to separate the Japanese bird on account of its larger size. 
The collection of a series of these birds made at Shaweishan 
(30 miles from the mouth of the Yangtse), all large birds, 
presumably bound for Japan or North-east Asia, induced 
me some years ago to study the question. The series I had 
previously collected was wholly from South-east China, all. 
being winter birds, and, with one exception, all of small 
size. Since then, I have obtained a series of summer birds 
from North-east Chihli in North China, and I have ascer- 
tained that these are all small birds, varying but BS in size 
from one another. 
Seeing, therefore, that the birds obtained or seen by me 
in their breeding-grounds of North-east China were all 
small-sized birds, and that the series obtained at Shaweishan 
on migration was entirely composed of large birds ; while a 
series of birds from Formosa, the Pescadores Islands, and
