PREFACE. 
I HAVE again the pleasure of acknowledging a grant of £100 
from the British Association for the Advancement of Science, 
a second contribution of £100 from the Government Grant Fund 
of the Eoyal Society, and a third contribution of £60 from the 
Council of the Zoological Society of London, in aid of this under- 
taking ; and I have also to thank my fellow Recorders for their 
continued co-operation.
