158 MR F. GOKDON PEARCEY ON 



Una sulHi/olioxu, Globigerina dutertrei, G. pachyderma, and Nonionina pompilioides. 

 This station is not far from Station 291, which yielded a more extensive collection ; and 

 it is probable that, if a larger quantity of material had been obtained, it would have 

 been found to be rich in the arenaceous types. 



STATION 291, lat. 67 33' S., long. 36 35' W. 



Depth 2500 fathoms. A greenish-gray gritty glacial mud with rock-fragments. 

 The sample examined consisted of washings from the mud taken in the trawl, the 

 finest mud and everything under ^ inch in size being washed away. 



The Foraminifera belong almost entirely to the Arenacea. Astrorhiza crassatina 

 is present in abundance, together with A. arenana, Saccammina, Thurammina, 

 Reophax, Hyperammina, Hormosina, Haplophragmoides, and Ammologena. The 

 only calcareous form found was one or two specimens of Miliolina bucculenta. 



STATION 295, lat. 66 40' S., long. 40 35' W. 



Depth '2425 fathoms; bottom temperature 31'3 F. A bluish-gray gritty glacial 

 clay. Only a very small quantity came to me for examination, so that nothing definite 

 can be said about the general facies of the Forammiferal fauna. The only two species 

 found were Astrorhiza crassatina, fragments, common, and Hormosina globulifera, a 

 few specimens. 



STATION 300, lat. 65 29' S., long. 44" 06' W. 



Depth 2500 fathoms; bottom temperature 32'l F. A fairly tough gray glacial 

 clay with gritty particles, containing 2 per cent of lime. 



A large amount of material was not available for examination, but the following 

 Foraminifera were found : Proteonina difflugiformis, Haplophragmoides subglobosum, 

 H. tndissatum, Cyclammina pus-ilia, Globigerina dutertrei, G. pachyderma, and Trun- 

 catidina pusilla. 



STATION 301, lat, 64 48' S., long. 44 26' W. 



Depth 2485 fathoms; bottom temperature 31'2 F. A dark grey glacial mud 

 with rock-fragments. A trace of lime. Only a very small amount available for 

 examination. 



The Foraminifera found were Saccammina sphserica (attached to a rock-fragment), 

 Bath i/siphon Jiliformis, Reophax nodulosa, and R. pilulifera. 



STATION 313, lat. 62 10' S., long. 41 20' W. 



Depth 1775 fathoms; bottom temperature 31'0 F. A bluish-gray, only slightly 

 coherent glacial muddy sand, containing 2 per cent, of lime. The material obtained 

 here from the trawl was large in amount, and, although a little of the finest material
