base, supercilia dull white, sides of head greyish brown, sides of neck, breast 
and flanks ashy ; chin and middle of throat white, abdomen white also, but 
less pure, lower tail coverts slightly fulvous, thigh coverts dark brown. A 
rather younger female has a browner back and flanks and indistinct super- 
cilium. 
The young birds agree with Dr. Stoliczka’s description, (.T. A. S. B. 
1868, Part II, p. 45) except that my specimens, which are perhaps females, 
have no white at the base of the tail. 
The measurements of my Sikkim specimen, except the tarsus and bill, 
are less than those given by Dr. Jerdon.

514 Cxanecula sttecica, (L.) — This was seen occasionally in the latter 
part of September, and more frequently in October, apparently coming from 
the north and migrating southwards. I shot one bird at Momay Samdong 
on the 19th September. 
In Mr. G. lv. Gray’s ‘ Hand list,’ the Indian blue-throat is still classed 
as C. ccerulecula, Pall., but Mr. Blyth, in the Ibis for 1867, p. 17, note, has 
shewn that it is identical with the Swedish form, the type of Motacilla suecica 
of Linnseus, and until Mr. Blyth has been proved to be in error on this point, 
the Indian race must bear the latter name.

558 Phtiioscopus* lugitbeis, Blyth. — This appears to be the com- 
monest warbler in Sikkim, and in all probability breeds abundantly in the 
higher parts of the hills. I met with it very frequently, solitary or in families, 
amongst the rhododendron bushes at elevations from 12,000 to 14,000 feet 
on the Chola range, and again from 10,000 to 13,000 or 14,000 in the pine 
forests of Liichung valley, associating in flocks with LopTioplianes and other 
birds. The specimens shot hy me have distinct whitish tips to the larger 
wing coverts, whereas in birds shot in the plains these are usually wanting, 
doubtless from their being gradually worn off ; my birds also are more yellow 
beneath, and the axillaries and edge of the wing are clear pale yellow, whilst 
birds shot near Calcutta are mostly greenish on these parts. There is, 
however, some variation in this respect. 
* If the type of Phyllopneuste, Meyer, be P. trochilus, the Indian birds ascribed 
to Phylloscopus by Jerdon must be placed in that genns. G. E. Gray, in his recent 
Hand-list, separates the Indian birds, which he places under Phyllopneuste, from P. 
trochilus, P. rufa, &c. classing these as Asilus, Moehring. I greatly doubt if the 
separation is justified by the structure of the bird. As I have not the means of 
clearing up this question, I use Jerdon s generic names.
