to enable me to exhibit an accurate exposition of every thing connected 

 with their physical geography, such as the height of their principal 

 summits, the general height, form, and direction of their valleys, the 

 climate of their different parts, the characters, and composition of their 

 soils, the nature of their springs and streams, their vegetation, and their 

 geology. With this view, I could establish my head quarters on 

 the Neilgherries ; for under any circumstances, it will be necessary for 

 me to have a fixed residence, where I may leave my books, apparatus, 

 and specimens ; and as long as I continue in the South of India, the 

 situation of these hills will be sufficiently centrical for this purpose. 



After having remained several weeks on the Neilgherries, I came to 

 Madras by way of Trichinopoly and the coast, in expectation of find- 

 ing some secondary formations near the former place. In this, however, 

 I was disappointed, and found that part of the country to possess but 

 little geological interest. On the coast I was more fortunate, having 

 discovered several curious deposits containing fossils, which are calcu- 

 lated to throw some light on the geological epochs of the Indian for- 

 mations. 



Since my arrival in India, I have made considerable collections in 

 Zoology, and have procured some very interesting specimens of fresh 

 water-fish, Crustacea, and insects. These it will be impossible for me 

 to describe, while engaged with my various researches in India. My 

 time while in this country, must be chiefly occupied with collecting 

 materials, which can be only arranged and described on my return to 

 Europe. 



Descriptions of three Indian species of Bat, of the genus Taphozous. 

 By Edward Blyth, Curator to the Asiatic Society. 



Of the several well-defined generic forms presented by the Insectivor- 

 ous Bats, a perfectly distinct one exists in the Taphozous of the Che- 

 valier Geoffrey St. Hilaire, or Saccopteryx of M. Illiger, which was 

 founded by the former eminent naturalist upon a species discovered by 

 him in the catacombs of Egypt, and which he has figured and described, 

 in the great national French work on that country, by the appellation
