THE PUBLICATIONS OP THE ZOOLOGICAL SOCIETY OP LONDON. 



The scientific publications of the Zoological Society of Loudon axe oH two kinds — "Proceedings," 

 published in au 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 jjjates and engravings are attached to each annual volume of the "Proceedings," to 

 illustratqi^e 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. 



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 £i 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 1871, if they exceed the value of five pounds. 



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

 for a sum of £\ (which includes delivery in the Unilred Kingdom only), but this privilege only 

 holds good if the subscription is paid before the Pirst of December in each year. 



Such of those publications as are in stock may be obtained at the Society's Office (3 Hanover 

 Square, W.), at Messrs. Longmans', the Society's publishers (Paternoster Row, E.G.), or through 

 any bookseller.
