less with bluish-white on the outer webs; tail-feathers brown, suffused with greyish-blue on both 
webs of the centre pair and on the outer webs of the others ; lateral tail-feathers with pale tips. 
Ear-coverts white, crossed by two broad dark russet-brown bands; chin, cheeks, and throat 
white; the rest of the underparts buffish-chestnut, shading into white on the belly, thighs, and under 
tail-coverts; axillaries bluish-grey, with white bases; lower primary-coverts bluish-grey ; lower 
secondary-coverts white, with bluish-grey bases. 
Geocichline markings on inner webs of quills, white. 
Bill black ; second primary intermediate in length between the sixth and seventh; tarsi, feet, 
and claws flesh-coloured ; outer tail-feathers 0:07 inch shorter than the longest. 
Length of wing 4:3 to 4:0 inches, tail 3-1 to 2:8 inches, culmen 0:9 to 0:85 inch, tarsus 1:9 to 
1:15 inch; bastard-primary projecting beyond the primary-coverts, its exposed portion measuring 1:0 
to 0:85 inch. 
The female is less bright in colour, the upper parts having a greenish-brown shade, with 
yellowish edges to the feathers, while the wings are shaded with green. 
Young in first plumage appear to be unknown. 
Ап example in my collection, apparently a female, though it is sexed a male, dated 
December 4th, has the terminal spots on the median wing-coverts rufous instead of white; and 
three males and two females in the British Museum, dated November, January, and April, have 
more or less obscure rufous tips to the greater wing-coverts; whilst three males in the same 
collection, shot in March and April have more or less obscure white terminal margins to 
the greater wing-coverts. АП these doubtless represent various stages of immaturity. 
The White-throated Ground-Thrush is very distinct from all its allies, and it is difficult 
to say to which of them it is most nearly related. It has the head and neck of Geocichla peroni 
joined to the body of Geocichla citrina; but there can be little doubt that its affinities are 
much more with the latter than with the former species. : 
The Plate shows a life-sized male of this species in my collection, obtained in the Ahmednuggar 
district by S. B. Fairbank on the 22nd of May, 1875. 
Jardine and Selby's figure of the type is also of life-size, and is a fairly good one, except that 
the artist has drawn the tarsus as scutellated in front, which of course is incorrect.
