456 TROGLODYTID®. 
triangular terminal spots of* blackish brown; in some cases the 
lower plumage is faintly tinged with fulvous, especially on the 
sides ; flanks brown obscurely barred with blackish ; under tail- 
coverts rufous The white colour of the lower parts at once 
distinguishes this race from all the others. 
Colours of soft parts. Iris red-brown ; bill dark horny-brown ; 
legs brownish-fleshy. 
Measurements. Wing 47 to 49 mm.; tail 37 to 39 mm.; 
tarsus 21 mm.; culmen 12 to 13 mm. 
Distribution. Chin Hills above 5,000 feet. 
Nidification. Major Venning and Mr. F. Grant found this 
Wren breeding in the Chin Hills between 5,000 and 9,000 feet in 
March, April and May, eggs being found between the 12th 
March and the 24th May, two fresh eggs having been taken on 
the latter date. The nest is typical of that of the genus. 
Venning describes one taken by him as “a large, oval, domed-shaped 
structure, composed of an outer layer of dead leaves, canna 
leaves, coarse grass, etc., inside which was a layer of grass stems, 
fibres and a little moss, the cup being lined up to the Jevel of the 
entrance witha plaster about 51, inch thick, composed, as far as I 
could determine, of a substance which looked like chewed thistle 
stem or chewed grass. The dimensions were: exterior height 
6 in., diameters 5 in. and 4 in.” Other nests taken were exactly 
like the one described ; they were all placed on damp ground in 
undergrowth ov grass in fcrest. 
The eggs, which number two to four ina full clutch, are not 
distinguishable from those of the Assam race. Fifteen eggs 
average about 18:2 x 14°6 mm. 
Habits. There is practically nothing on record about this bird, 
but it is not likely that its habits differ in any way from those of 
the other races. It, however, seems occasionally to be found in 
rather more open country.
