f\ftin])lc I hftve yet seen of this bird, which appears to have escaped 

 the iKttice of" the Kieiuh ornitholoirists. It is marked as having 

 been received iVoin I^\«:nta in ISl.*^ hy M. Riefl'er. Its form is typi- 

 cal, b»it in colonriiia: it (Urters from all hitherto known mend)ers of 

 the pMius, tlioui:h j)erh:i]is showing some resend)lanee to GraUaria 

 brcvicauda (Hodd.) (I'l. Eid. 7('(i. tig. 1), which is, however, much 

 smaller. It is of a uniform frmiginons brown above and white be- 

 low, ]»assing into a cinereous tinge on the sides. Some brown colour 

 is mixed with the feathers on the sides of the breast. The bill is 

 black, the tarsi ])lumbeous ; the tliighs and the under wing-coverts 

 brown.

 This is a rather uniformly-coloured -species, of which the British 

 Museum contains a single specimen. There are indications of darker 

 marginations to the feathers of the nape and back. The breast fea- 

 thers are medially yellowish-white, broadly margined w ith olivaceous.

This peculiar Ant-thrush, of vvhich there is one specimen in the 

 British Museum, has the lower back very densely feathered, the 

 coverts reaching to within an inch of the end of the rectrices. The 

 wings are shorter than is usual in Chamceza — the 4th, .^th, fith and 

 7th primaries being nearly equal in length, but the 5th rather the 

 longest ; the tail rather more lengthened ; the formation of the feet 

 is much the ssime. 



Above the colouring is of a brown chestnut, rather darker towards 

 the tail ; the sides of the head and whole under-plumage are blackish 

 barred with white, every feather having three or more transverse 

 white bars. A slight tinge of castaneous is intermixed, particularly 

 on the breast.
