THE PUBLICATIONS OF THE ZOOLOGICAL SOCIETY OF LONDON. 



The scientific publications of the Zoological Society of London 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 in the " Proceedings " by the Committee of Publication. A large number 

 of coloured plates and engravings are issued in the "Proceedings," to illustrate the new or 

 otherwise remarkable species of animals described in them. Among 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, in the months of IMarch, June, 

 September, and December. From January 1901 they have been issued as two half-yearly volumes, 

 indexed separately. The pagination is now consecutive throughout the issue for the year, so that 

 the year and page give the complete reference. 



An " Abstract of the Proceedings " is published by the Society on the Tuesday following the 

 date of Meeting to which it refers. It is issued along with the " Proceedings," free of extra charge, 

 to all Fellows who subscribe to the Publications, biit it may be obtained on the day of publication at 

 the price of Sixpence, or, if desired, sent post free for the sum of Six Shillings per annum, payable 

 in advance. 



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 issued at irregular intervals. 



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 1881, if they exceed the value of five pounds. 



Fellows also have the privilege of subscribing to the Annual Volume of the ' Zoological Record' 

 for a sum of £1 10s. (which includes delivery), payable on the 1st July in each year; but this 

 privilege is forfeited unless the subscription be paid before the 1st December in each year. 



Such of these publications as are iu stock may be obtained at the Society's Ofiice (Regent's 

 Park, London, N.W,), at Messrs. Longmans' the Society's publishers (Paternoster Row, E.C.), or 

 through any bookseller.
