Mr. G. N. Lawrence on a new Species of Thrush. 57 
think, a distinct species, very close, it is true, to both M. 
atra and M. chalyheata, but exactly intermediate, and pos¬ 
sessing characters of both species. In the texture of the 
feathers of the head, breast, and mantle, M. johiensis is close 
to M. chalyheata; but in the rest of its plumage, and especially 
in the form of the bill, it resembles very closely M. atra. The 
culmen is compressed, and does not spread at the base as in 
M. chalyheata.

[We have tried in vain to make this specimen, which Mr. 
Lawrence has sent to us for examination, fit some described 
species. It is perhaps nearest to T. leucomelas, but is of a 
darker brown, and has the chest washed with a strong tinge 
: of the same colour. The under wing-coverts are of a deeper 
rufous, in which respect it approaches T. albiventris. — Edd.]
