INTRODUCTION.
The present is the first part of a general work, compiled for the Government, and published under its authority, on the Fauna of British India and its dependencies. A few details respecting this larger work may serve as a preface to the introductory observations on the Mammalia.

For the present, it is proposed to restrict the publication to the Vertebrata, and to complete the work in seven volumes of about 500 pages each. One of these volumes will contain the Mammals (the present issue is only a half-volume), three will be required for the Birds, one for Reptiles and Batrachians, and two for Fishes.
