PUBLICATIONS 
OF THE 
ZOOLOGICAL SOCIETY OF LONDON. 
Ur to the close of the year 1860, the scientific publications of 
the Zoological Society were of two kinds—“ Proceedings,” pub- 
lished in an octavo form, and “ Transactions,” in quarto. In 
accordance with a recent change in the By-laws, these two 
publications were united, at the commencement of the year 1861, 
under the title “‘ Proceedings of the Scientific Meetings of the 
Zoological Society of London.” 
According to the present arrangements, the “ Proceedings” 
contain not only notices of all business transacted at the scien- 
tific meetings, but also all the papers read at such meetings 
and recommended to be published by the Committee of Pub- 
lication. From thirty to forty 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 three parts, 
in the months of May, August, and February, the part pub- 
lished 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, and to receive the Illustrated Proceedings of the 
Society at a fixed subscription price of 10s. per part, or £1 : 12s. 
for the annual volume, bound in cloth. 
The “ Transactions,” of which the last part of Vol. IV., com- 
pleting the series, is now nearly ready for publication, contain 
such of the more important communications formerly made to 
the scientific meetings of the Society as, on account of the nature 
of the plates required to illustrate them, were 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.
