upper tail-coverts, tertiaries and lower back feathers margined with 
blue ; brownish-olive on the neck and breast ; underparts more or 
less white with chesnut coloured flanks. This Janthia builds at 
high attitudes. You will, most probably find cyanura constructing 
its nest not far from the snow line. Where I saw it beyond Jongri, 
usually beside old fallen trees, or where there are no trees about the 
place, it builds in holes dug out of the bank above the road. The 
eggs are whitish with a delicate green tinge, roundish in shape or 
broad oval much pointed at the small end ; at the large end is a zone 
formed by minute specks of reddish-brown, usually a bit faded in 
appearance. Nest is of moss outside, lined within with soft white 
fibres and grass. These birds are much like other species of wood- 
chats, they keep a good deal to thick jungle cover, where such 
places are available. ° They are tame and exhibit the confiding char- 
acteristics of Robins. 
We will examine a few more well marked species, and likely 
birds to be more readily found in the district. 
(511) TARSIGER CHRYS&US, Golden Bush-chat, is found at a 
lower attitude. It seldom ascends much over 5,000 feet. I saw 
this bird on more than one occasion ou the Ging Spur. This Bush- 
chat is a beautifully coloured bird, which appears in thick, green 
foliage like a flash of light, or burnished gold, in the sun, when seen 
playing about the bushes in its retreat among tangled undergrowth 
jungle in the district or in Sikkim. Tarsiger is 5} inches in size 
wing expanse about 9 inches ; irides dark brown. Colour, above, is 
olive green, on the head, nape and back; bright golden yellow on 
lower back, tail and whole of lower parts of the bird; tail broad 
tipped with black it has a golden yellow superciliary streak and a 
more prominent black streak on sides of the head passing through 
ear-coverts. J arsiger is solitary in its habits. It mixes freely, how- 
ever, with other birds in the locality. It is usually shy, when 
observed it remains but a few seconds, then flits back into thick 
jungle cover. 
GENUS. CALLIOPE, Jtuby-throats, are common in the plains, 
where they are winter visitants.. In summer they retire to high 
altitudes on the Himalayas, central and Northern Asia. Bill of 
these birds, is of moderate length and fairly strong ; wings of ordi- 
nary, size ; tail slightly rounded ; tarsus longish and stout ; feet large; 
hind toe long and claws long. 
(512) CALLIOPE KAMTSCHATKENSIS, Common Ruby Throat, arrives 
in the cold weather in the district, it keeps to the terai, and shows 
but little inclination to ascend, or even get to foot of the hills. I
