ment for the promotion of Science. To that Committee, and to 
the guarantors of the fund of the Zoological Record Association 
who ha\e, on the expiration of the original term, renewed their 
liability for the support of this undertaking, the best thanks of all 
Zoologists are most justly due. 
There remains a great boon to Zoological students to be formally 
acknowledged — I refer to the publication in 1873, by Count August 
von Marschall, under the auspices of the Royal Zoological-Botanical 
Society of Vienna, of a " Nomenclator Zoologicus," continuing the 
indispensable work of the same name by L. Agassiz, from the date 
at which the latter ended (1846) to 1868, inclusively. On the vast 
labour expended upon the 482 closely printed . pages of this volume 
it would be superfluous to comment ; and it may be safely asserted 
that no work of such general utility has appeared for very many 
years. Lists of the genera recorded during each year since 1870, 
inclusively, having been added to the volumes of the Zoological 
Record from that date, it has occurred to me that a similar table 
of the genera comprised in the volume (vi.) for 1869 of this pub- 
lication would not be altogether useless, as connecting the Vienna 
" Nomenclator " with our own periodical series, and thus com- 
pleting the record of genera to the present day. I have accordingly 
compiled such a list, which will be found on the eight pages follow- 
ing these remarks. Many genera can hardly fail to be omitted 
from such an undertaking ; but a basis for a complete work will 
be by these means afforded.

Communications, papers, and memoirs intended for this work 
should be addressed so^eZ/y to " The Editor of the Zoological Record, 
care of Mr. Van Voorst, 1, Paternoster Row, London." It is earnestly 
requested that in the case of separately-printed copies of papers so for- 
warded the oriijinal imagination be indicated.
