PUBLICATIONS 



OF THE 



ZOOLOGICAL SOCIETY OF LONDON. 



The scientific publications of the Zoological Society are, accord- 

 ing to their By-laws, 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 the business transacted at the scien- 

 tific meetings, but also all the more important papers read at 

 such meetings in eoctenso, with the exception of some of those 

 published in the "Transactions," of which abstracts only are 

 given. The papers which appear in the "Transactions" are, 

 however, often also printed in the " Proceedings." From twenty 

 to thirty coloured plates and engravings are attached to each an- 

 nual volume of the " Proceedings," to illustrate the new or other- 

 wise 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 now issued in three 

 parts, in the months of May, August, and February, the part 

 published in February completing the volume for the preceding 

 year. They may be obtained with or without the illustrations. 



The "Proceedings" without illustrations are delivered to the 

 Fellows of the Society gratis on demand. The Fellows are like- 

 wise entitled to purchase all the other publications of the Society 

 at a reduction of one-fourth from the price at which they are 

 published. 



The " Transactions" are published in parts at irregular inter- 

 vals. They 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. The numerous 

 and elaborate papers of Professor Owen on the Anthropoid 

 Apes, and on the various species of Dinornis, all form part of 

 this series. 



The following is a complete list of the publications of the 

 Society already issued. They may be obtained at the Society's 

 Office (11, Hanover Square, W.), at Messrs. Longmans' the 

 Society's publishers, or through any bookseller.
