PREFACE. 
In spite of the arrangements made for a more speedy issue of tlie 
present volume, its publication has been delayed, chiefly in con- 
sequence of the engagements of the Recorder of Aves. This 
important section has, however, been kindly undertaken, for the 
next volume, by Mr. Osbert Salvin. 
I have again the pleasure of acknowledging a grant of £100 
from the British Association for the Advancement of Science, and 
a second contribution of £60 from the Council of the Zoological 
Society of London, in aid of this undertaking ; and I have also to 
thank my fellow Recorders for their continued co-operation.
