INTRODUCTION. 
By the study of Foraminifera under abnormal or adverse 
conditions one is able to learn much that is of biological interest, 
and more of the real value of the so-called species, than by the 
mere examination of samples which have been obtained from 
ordinary extensive littoral or deep-sea deposits, formed under 
conditions more or less favourable. 
So far as I know, we have never before had so good an oppor, 
tunity of examining a foraminiferal lagoon fauna in detail. The 
present paper is based on the material dredged by Messrs. G. 
Halligan and A. E. Finckh across the lagoon of Funafuti; and

of Sydney University, under whose direction the dredgings were 
made. |

intervals of half-a-mile, until the opposite rim of the Atoll was
