192 Notes and Queries. [No. 3, 
Prof. Westwood was unable to recall any analogous phenomenon ; 
the simultaneity of the flight of Hmpis over standing water seemed 
to be the nearest in point. 
The following is from our late Curator. 
The Inuwus assamensis. 
In the Notes and Queries published in the last page of the Society’s 
Journal for 1864, Capt. T. Hutton remarks that in my Catalogue of 
the species of mammalia in the Society’s museum, I “ make Inuus 
assamensis of Maclelland and Inwus pelops of Hodgson to be one and 
also, that I “never saw a specimen of Pithex (Inuus) 
pelops of Hodgson.” 
Referring to my Catalogue, I find that I placed Pithex pelops, 
Hodgson, as a synonyme of J. assamensis on the authority of the late 
Dr. Horsfield. Vide his Catalogue of the species of mammalia in the 
old India-house museum, now at Fyfe House. 
the same;” 
Capt. Hutton may remember that he brought two living individuals 
of what he considered to be JI. pelops to Calcutta, many years ago, 
from Mussoorie, which I saw repeatedly in his presence, though not to 
much advantage in the small cage in which they were confined. 
When his family proceeded to England, those monkeys were shipped 3 
but what afterwards became of them, I am unaware. 
Did Capt. Hutton ever see a specimen of I, assamensis, that he is 
enabled to pronounce so confidently on its specifical distinctness from 
I. pelops ? 
Not long ago, I examined the original specimen of J. assamensis 
procured by McClelland, which still remains unique; and I could not 
perceive that it differs in any respect from the common J. rhesus, 
excepting that the hind part of the body is not, as usual, strongly 
tinged with bright ferruginous or tawny, being uniformly coloured 
with the rest ; and my present impression (liable to correction) is, that. 
it is merely an individual variety of colour of the common animal of 
Lower Bengal. 
Indian Rats and Mice. 
With reference to my paper on these animals (J. A. 8. XXXII, 
327 et seq.), I hoped to have been able to reduce the number of nomi- 
nal species considerably, on examination of the specimens in the 
British museum and the India museum ; but the less known of them
