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. chalybeata, but exactly intermediate, and pos- 

 sessing characters of both species. In the texture of the 

 feathers of the head, breast, and mantle, M. jobiensis is close 

 to M. chalybeata ; 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. chalybeata.

Type in my collection. 



[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.]
