W. T. Blanford — Zoology of Sikkim. 
Hirundinidce. 
93 CheIjIDON Casiimieiensis, Gould. — Common on the Chola range 
about the upper limit of forest, 12,000 to 13,000 feet. It was chiefly seem 
hunting over streams and lakes. 
Laniidce. 
258 Lantus TEPHBONOTrs (Vigors). — Common at Lachung, 8,000 to 
9,000 feet in the beginning of September, but three weeks later all had disap- 
peared. Many of those seen were in young plumage with hair on the breast, 
back, and scapulars. 
Campepliagidce. 
274 Pebicrocotus Solaris, Blyth. — I shot a female from amongst a 
flock at about 10,000 feet elevation near Lachung. 
There is evidently a misprint in Jerdon’s description of the female of this 
bird. It is the back which is olive green, the lower parts are deep yellow 
passing into whitish on the throat. The rump is dark yellow with a slight 
brownish tinge. 
The female of P. Solaris is distinguished from that of P. irevirostris 
by its shorter bill, greyer head, ashy ear coverts, whitish throat, and especially 
by wanting the broad yellow forehead of the last named species, which I 
found abundant in the Tista valley at elevations below about 6,000 feet. 
Muscicapidee. 
296 Hemickelihon siberica, (6m.) . — H.fuliginosa, Hodgs. 
One young specimen obtained in the Lachen valley at about 9,000 feet. 
294 Chelidoehtnx iiypoxantiia (Blyth). — Common in pine forests 
at the foot of the Chola pass at about 12,000 feet elevation. In the interior 
I did not notice it above about 8,000 feet, below that it abounded. It was 
usually seen in small flocks, hunting about trees. 
319 Siputa stbophiata, Hodgs. — The only fly-catcher commonly seen 
in the pine woods of the Lachung and Lachen valleys. Here it was found 
up to an elevation of 12,000 feet, associating with tits, Sylviads, and Ixuli. 
It was also common on the Chola range at the same elevation. The white 
on the rectrices decreases on the outer feathers, as noticed by Stoliezka in 
specimens from N. W. Himalayas. (J. A. S. B., 1868, Bait ii, p. 32). 
The plumage of the young bird does not appear to have been described ; 
the following is that of a specimen shot at Yeomatong, hi the upper Lachi'mg 
valley, on September 12th. Upper parts and sides of the head and neck brown, 
the feathers of the head with narrow brownish yellow streaks down the centre ; 
these increase in size till, on the back, the feathers are brownish yellow with 
dusky brown margins ; the same on the rump, but the colour is a little less 
brilliant. Quills and coverts dark brown, broadly edged with rufous brown,
