During the calendar year 1923 the following volumes of the 6 Fauna of British India' appeared—Diptera, Vol. III. Pipunculidae, Syrphidae, Conopidae, AEstridae, by E. Brunetti, and OligochaETA, by Dr. J. Stephenson.
In 1922 the first volume of the Aves, re-edited by Mr. E. C. Stuart Baker, was published. The present volume contains a further instalment of the Passeres including the Cinclidae (Dippers) ; Turdidae (Thrushes, Chats, etc.) ; Muscicapidae (Flycatchers) ; Laniidae (Shrikes) ; Dicruridae (Drongos) ; Sylviidae (Warblers), and Regulidae (Goldcrests, etc.). It is hoped that a third volume will complete the Passeres and possibly also include the Woodpeckers, Barbets and other birds contained in Volume III. of the first edition with the exception of: the Strigidae and Falconidae.
Certain additions and alterations have been made in the form in which the first volume of this edition appeared. These it is hoped will be an improvement and will be of use to readers other than pure field-naturalists and observers. The first reference to each genus and also the type o£ the genus and the type-locality have been given. When the typical form of any genus or species is " extra-limital " to the area included in this work, similar references have again been given and also a brief note showing how the nearest form in Indian limits differs from the typical one.
Finally, separate keys to the subspecies have been given as well as keys to the species ; these it is hoped will facilitate identification.
I may add that the present volume is in other respects fully up to the standard set by the author in his previous publication of: eighteen months ago.

This second volume of the Avifauna contains a further instalment of the Passeres, including 473 species and subspecies, bringing the total number dealt with up to date to 049. The second volume of the Avifauna has appeared within about 20 months of the first, although the prescribed period between the publication of each issue is supposed to be two years. This is due to the persistence of our Editor, Sir Arthur E. Shipley, and, it must be added, to the fact that the Authorities concerned fully appreciate the value of rapid production in a work of this nature. A still more important success gained by the Editor is sanction to a sixth volume to the Avifauna, which is to contain a full Synonymy of all first references in addition to corrigenda and addenda to the first five volumes.
It is hoped that the third volume will be completed in another 18 months or less and that subsequent volumes -will appear at even shorter intervals. Headers will, however, realize that any work which entails the consideration of sub-species—a new factor in Indian Zoology—also entails an enormous amount of Museum work, which cannot be hurried over. Nomenclature, also, is at present in such a state of flux that it is extremely difficult to follow the writings of those who make a special study of this subject, in addition to the original research work the Author himself has to get through.
