PREFACE. 
♦ 
The thirty-sixth volume of the Zoological Record is complete 
in itself; including, as it does, a record in each of the eighteen 
divisions, and no arrears having remained over from last year. 
The Editor has the pleasure of thanking the Recorders for 
their work on behalf of the Zoologists of the world, and for 
the punctuality they have displayed in carrying out their tasks. 
He also desires to thank the Librarians who have assisted 
him in revising and perfecting the list of Abbreviations and 
Periodicals. 
The Editor wishes to call attention to the advertisement, 
annexed to this Volume, announcing the intention of the Zoolo¬ 
gical Society to publish an Index to the names of genera and 
sub-genera, 'Supplementary to the Nomenclator Zoologicus of 
S. H. Scudder. It is intended to include in this List all names 
omitted from Scudder s Nomenclator and from the Zoological 
Record subsequent to 1879. The work is already well advanced, 
and it is hoped that any Zoologist who may know of omissions 
from the works mentioned will send the omitted names and 
references to Mr C. 0. Waterhouse of the British Museum, 
Natural History, or to the Society. As many years may elapse 
before a complete Index of the described genera and species 
of animals can be published, it is important that this interim 
work should be made as perfect as possible.
