PREFACE. 
I HAVE again the pleasure of acknowledging a grant of £100 from 
the British Association for the Advancement of Science, in aid of 
this undertaking ; and of thanking the Recorders who continue their 
valuable assistance. Having been enabled by their efforts to bring 
out this volume within a few months of its predecessor, the Record 
of the Zoological Literature of one year is now published during the 
next one, for the first time since 1870. I have confidence that this 
rate of issue will henceforth be maintained, and I can only express 
the hope that it may not be at the expense of accuracy and com- 
pleteness. This earlier appearance has prevented the application 
to the Royal and Zoological Societies for those annual grants in aid 
which it has hitherto been my duty and pleasure to acknowledge, 
and which I trust will nevertheless be extended to us as before.
