MIXORNIS. 273 
Kloss’s connectens I cannot separate from pileata the South Malay 
form and his name therefore becomes a synonym of that bird. 
Variation inter sz is so great in the birds of this species that it is 
quite unsafe to found geographical races on anything but very 
large series.

Nidification. The Yellow-breasted Babbler breeds during April,

with a meagre lining of finer grass, which it places either in a 
bamboo clump or a bush close to, but not on the ground ; 
occasionally 4 or even 5 feet above it. The eggs, generally 
three, sometimes two only or four, are china-white with numerous 
specks and small blotches of red and reddish brown distributed all
