PREFACE. 
I HAVE the pleasure of acknowledging the following grants in 
aid of this undertaking : — dBlOO from the British Association 
for the Advancement of Science ; dBlOO from the Government 
Grant Fund of the Royal Society (the sixth contribution) ; and 
£50 (the seventh contribution) from the Council of the Zoological 
Society of London. 
In thanking such of the Recorders as continue their assistance in 
this arduous work, I have to notice with regret the loss of three of 
my former fellow-labourers, two of whom have very suddenly been 
taken from us. 
The late Mr. Alston’s engagements prevented him from writing 
the Record of Mavimalia^ which he had for six years so ably under- 
taken ; he had, however, before his lamented death, supplied a most 
efficient substitute in Mr. W. A. Forbes, Prosector to the Zoological 
Society. 
The late Mr. O’Shaughnessy, another valued contributor of equal 
long standing, did not intend to undertake the JReptilia and Pisces 
in future, but had provided a successor, Mr. G. A. Boulenger, 
whose work at the British Museum is sufficient guarantee of his 
capability. 
Finally, Dr. Liitken has found that he can no longer devote 
sufficient time to the Record of Gcelenterata, and has therefore 
reluctantly given up that work. It may appear invidious to Mr. 
A. G- Bourne, of the Zoological Laboratory, University of London, 
and Mr. S. J. Hickson, of Downing College, Cambridge, who have 
at a short notice most efficiently undertaken that difficult group 
between them ; but it is nevertheless impossible to avoid the expres- 
sion of sincere regret at the loss of so distinguished a writer.
