GLOBIGERINIDiE. 279 



much the same relationship to U. Canariensis as U. tenuistriuta has to JJ. 



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

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

 sands to 1900 fathoms ; and the specimeiis were obtained from several widel}^ 

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



Bgger, in his Memoir on the Foramiuifera obtained by the ' Gazelle,' records 

 specimens from off 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 Red 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.
