THE PUBLICATIONS OP THE ZOOLOGICAL SOCIETY OF LONDON. 



The scientific publications of the Zoological Society are of two kinds — " Proceedings," published 

 in an octavo form, and " Transactions," in quarto. 



According to the present arrangements, the "Proceedings" contain not only notices of all busi- 

 ness transacted at the scientific meetings, but also all the papers read at such meetings and recom- 

 mended to be published by the Committee of Publication. From fifty to seventy coloured plates 

 and engravings are attached to each annual volume of the " Proceedings," to illustrate the new or 

 otherwise remarkable species of animals described in them. Amongst such illustrations, figures of 

 the new or rare species acquired in a living state for the Society's Gardens are often given. 



The " Proceedings " for each year are issued in four parts, on the first of the months of June, 

 August, October, and April, the part published in April completing the volume for the preceding 

 year. They may be obtained with black or coloured illustrations. 



The " Transactions " contain such of the more important communications made to the scientific 

 meetings of the Society as, on account of the nature of the plates required to illustrate them, are 

 better adapted for publication in the quarto form. They are published at irregular intervals ; but 

 not less than three parts are usually issued in each year. 



Fellows and Corresponding Members, upon payment of a Subscription of ^1 Is. before the day of 

 the Anniversary Meeting in each year, are entitled to receive all the Society's Publications for the 

 year. They are likewise entitled to purchase the Publications of the Society at 25 per cent, less 

 than the price charged for them to the Public. A further reduction of 25 per cent, is made upon 

 purchases of Publications issued prior to 1861, if they exceed the value of five pounds. 



Such of those publications as are in stock may be obtained at the Society's OfiBce (11 

 Hanover Square, W.), at Messrs. Longmans', the Society's publishers (Paternoster Row, E.C.), 

 or through any bookseller.
