102 Notes and Queries. [No. 3, 



Prof. "VVestwoocl was unable to recall any analogous phenomenon ; 

 the simultaneity of the flight of Empis over standing water seemed 

 to be the nearest in point. 



The following is from our late Curator. 



The Inuus 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 Inuus pelops of Hodgson to be one and 

 the same ; " also, that I " never saw a specimen of Pithex (Inuus) 

 pelopjs of Hodgson." 



Eef erring to my Catalogue, I find that I placed Pithex pelops, 

 Hodgson, as a synonyme of I. 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. 



Capt. Hutton may remember that he brought two living individuals 

 of what he considered to be /. 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 ; 

 but what afterwards became of them, I am unaware. 



Did Capt. Hutton ever see a specimen of J. 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 /. assamensis 



procured by McClelland, which still remains unique ; and I could not 



perceive that it differs in any respect from the common /. 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. S. 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
