Almost the only migrant which we found in Sikkim commonly, before the cold 
weather birds appeared from the north, was Phylloscopus lugubris, and in the 
sub-family to which this belongs P. tristis, P. fixed t us, P. viridanus , and, per- 
haps one or two species of Peguloides breed, so far as is known, in Central or 
Northern Asia, and visit India in the cold weather, whilst Phylloscopus 
fuliginiventer, Peguloides erochroa and several species ol Alrornis are 
peculiar to the Himalayas.* 
It should be remembered that the collections made by Captain Elwes 
and myself were procured under great disadvantages. For the greater por- 
tion of the time, on the Chola range especially, the weather was most unfa- 
vourable. Every field ornithologist knows how in wet and misty weather birds 
are silent and skulk amongst the bushes where it is most difficult to see 
them, whilst in bright sunshine they are constantly in the open. It is 
probable that any one visiting the highlands of Sikkim at a more favourable 
season, such as May, or October and November, would find very much to add 
to our observations. 
I much regret having been unable, from want of time, to give any notes 
on invertebrata. My collections, however, were very small. 
MAMMALIA. 
QUADRUMANA. 
Presbytis schistaceits, Hodgs. 
Jerdon, in the ‘ Mammals of India,’ says that this monkey has not, to 
his knowledge, been obtained in Sikkim. Hooker mentions large monkeys 
near Lamtengt and again on his road from LachungJ to the Tankra pass, in 
both cases in pine woods. I saw none myself, hut several were shot by a 
shikari of Captain Elwes near Lachung, thus rendering it nearly certain 
that it was this species which was noticed by Hooker, for no other large 
monkey is likely to be found at an elevation of 9,000 and 10,000 feet. 
1 greatly doubt if the Langurs mentioned by Jerdon as occurring near 
Pankabari belonged to this species, because it is extremely improbable that 
an animal found at considerable elevations in the Western Himalaya, should 
also occur amongst the purely Malay forms of the Sikkim Terai. P. schis- 
taceus has never to the best of my knowledge been found on the outer 
bills of' Sikkim, the fauna of which is Malay, and it is perfectly natural to 
* More Indian birds appear to breed in the Western Himalayas, bat even here 
many cross the principal snowy range. I cannot agree with Lord Waldon’s opinion 
in this matter, (Ibis, 1867, p. 214 note), but much has been added to our knowledge of 
the summer haunts of tho Indian Passerines during the last two or three years.
