INTRODUCTION. 
The Record for 1897 is again somewhat smaller than its predecessors. 
The steady decline in the number of papers published on Protozoa for the 
past four years is noteworthy and is principally due to a diminution of 
the energy with which certain pathological problems were till recently 
attacked. 
Perhaps the event calling most for remark here is the conclusion of 
Rupert Jones’ “Monograph of the Foraminifera of the Crag” (20) 
begun so many years ago ; whilst the same author and Mr Frederick 
Chapman conclude their joint work on “The Fistulose Polymorphince 
and on the genus Ramulina ” (71). Lister (96), in the Proceedings of 
the Cambridge Philosophical Society, has attempted an explanation of 
the arrangement of the chambers in the biloculine and triloculine 
1897. [Vol. xxxiv.] f 2
