defined deposit, except in the case of the pelagic species, which are known to diminish 

 size and numbers the farther south research is made. It is to the bottom- 



in 



living forms we must specially look, to furnish us with definite information on the 

 important questions relating to the geographical distribution of the Foraminifera. From 

 present information, however, it would appear, with the exception of two or three 

 genera and species, that the Foraminiferal fauna of both polar regions is strikingly 

 similar a fact which is probably connected with the generally uniform conditions of 

 temperature extending over the bottom of the deep sea from pole to pole. 



List of Stations at wJiich Foraminifera were obtained from the Deposits, 

 with their Position, Depth, and Nature of the Bottom. 



The examination of the Hcotia deposits with regard to Foraminifera goes to prove, 

 as did the Challenger work, that Foraminifera are more abundant and attain a higher 

 development in size, especially the arenaceous forms, the nearer we approach the 

 slopes of continental land between depths of 500 and 1000 fathoms, even though the 



* This sample was taken by the trawl between two soundings, viz. that at Station 467 and that at Station 469, 

 the latter depth being 2900 fathoms, in 39 i27' S., 5 50' E. The probable depth is therefore about 2700 fathoms.
