much the same relationship to JJ. Ganaviensis as TJ. tenuistriata has to U. 

 pijgmsea. 



Occurrence. — The typical TJvigerina Canariensis has a wide geographical and 

 bathymetrical range. The ' Challenger ' records as to depth vary from shore- 

 sands to 1900 fathoms ; and the specimens were obtained from several widely 

 separated stations in the North and South Atlantic, and in the South Pacific. 



Egger, in his Memoir on the Foraminifera obtained by the ' Gazelle,' records 

 specimens from ofi" the coasts of Mauritius, "Western Australia, and New Guinea. 



We have specimens in our own collections from soundings obtained by 

 H.M.S. ' Penguin ' from two stations in the Indian Ocean, one of them due south 

 of Ceylon, at depths of 1040 and 1277 fathoms respectively. 



In the fossil condition specimens have been obtained from the Chalk of Taplow ; 

 the Miocene of Vienna and Muddy Creek (Victoria), and the Pliocene of Kar 

 Nicobar. In the Coralline Crag we have specimens from Tattingstone, zone d ; 

 Sutton, zone e; and Gedgrave, zone f. In the First Part of this Monograph, 

 U. Canariensis (" IT. irregularis ") was recorded from the Eed Crag (Appendix I, 

 Table, No. 59 ; App. II, Table, No. 73) ; but the specimen has been lost. Var, 

 farinosa (Hantken) is from the Tertiary of Hungary.
