32 W. T. Blanford— Zoology of Siklcim. [No. 1, 



Almost the only migrant which we found in Sikkim commonly, before the cold 

 weather birds appeared from the north, was Pliylloscopus lugubris, and in the 

 sub-family to which this belongs P. tristis, P. fuscatus, P. viridanus, and, per- 

 haps one or two species of Regidoides breed, so far as is known, in Central or 

 Northern Asia, and visit India in the cold weather, whilst Pliylloscopus 

 fuliginiventer, Peguloides erochroa and several species of Air amis 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 weatber 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. 



Presbttis schistaceus, 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 Lamtengf and again on his road from LachiingJ to the Tankra pass, in 

 both cases in pine woods. I saw none myself, but 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. 



I greatly doubt if the Langurs mentioned by Jerdon as occurring near 

 Pankabari belonged to this species, because it is extremely improbable tbat 

 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 

 hills of Sikkim, the fauna of which is Malay, and it is perfectly natural to 



* More Indian birds appear to breed in the Western Himalayas, but even here 

 many cross the principal snowy range. I cannot agree with Lord Walden's opinion 

 in this matter, (Ibis, 1867, p. 214 note), but much has been added to our knowledge of 

 the summer haunts of the Indian Passerines during the last two or three years.
