PREFACE. 
I have again to acknowledge grants of £100 from the British 
Association for the Advancement of Science, and of £150 from 
the Government Grant Committee of the Royal Society, in aid of 
this undertaking. 
Further changes will be noticed among the Recorders, Mr. S. 0. 
Ridley’s place in the Spongice being occupied by Prof. W. J. Sollas, 
and Mr. W. Saville-Kent’s in the Protozoa by Prof. A. C. Haddon. 
It is a subject of regret that the other engagements of the Rev. 
0. P. Cambridge have not only prevented the delivering of his 
Record of Arachnida in time for insertion in this volume, but 
practically deprive us of his aid in future. The Arachnida for 
1883 and 1884 will be given in the next volume, by Mr. T. D. 
Gibson -Carmichael.
