Geocichla erythronota, G. dohe : 
| lores and ear-coverts and the white throat of the 
chestnut backs of the two former, and the black 
latter, serve to distinguish them at once. 
'The adult male and female may be described as follows :—General colour of the upper parts 
dark slaty grey, sharply defined from the nape, whic 
chestnut, brighter towards the nape; lores white ;

black fan-shaped terminal spots, which become obscure on the flanks; axillaries dark slaty grey, with 
white bases ; lower primary-coverts nearly black ; lower secondary-coverts white, with nearly black

Geocichline markings on inner webs of quills, white. 
Second primary intermediate in length between the seventh and eighth : “bill very dark brown; 
legs pinky white; claws horn-brown; iris chocolate" (4. Н. Everett). Outer tail-feathers very 
slightly shorter than the longest. 
Length of wing 4:25 to 4:0 inches, tail 2:4 to 2:2
