Polystomella imperatrix, II. B. Brady. 



Taken (rare) at Station 118. /*. imperatrix is by no means a common species, 

 but is the largest and most handsome of all the Polystomella. So far as 1 am aware, 

 it has not been found north of the equator. 



Polystomella crispa (Linne). 



This common cosmopolitan species was obtained in abundance at Station 346, 

 56 fathoms. 



Polystomella verriculata, H. B. Brady. 



This rare species was also taken very sparingly at Station 346. P. verriculata 

 has hitherto only been found at two points on the west coast of Australia, namely, off 

 East Moncoeur Island, 38 fathoms ; and in Curtis Strait, Queensland, by the Challi'n</>:r 

 Expedition. 



COMPARATIVE VIEW OF THE MORE PROMINENT FORAMINIFERA 

 OBTAINED FROM THE VARIOUS SAMPLES OF DEPOSITS EXAMINED. 



As the material in most cases was insufficient to give a full representation of the 

 Foraminiferal fauna, reference is made only to the main features of the groups 

 actually found. 



In the case of Stations 313 and 420, where the material was abundant, full lists are 

 given, as these stations (with certain exceptions, referred to under the individual 

 stations) may be taken as representative of the northern and southern parts of the 

 glacial deposit area in the Weddell Sea. 



STATION 118, Stanley Harbour, Falkland Islands. 



Depth 2j fathoms ; bottom temperature 5'2 F. A dark brown mud with a 

 greenish tint, containing 27 per cent, of lime from calcareous organisms of various kinds. 

 The chief Foraminifera are Bulimina elegantissima, Rotalia karsteni, and Polystome/ln 

 striatopunctata. Proteonina difflugiformis, Trochammina nitida, and T. nana 

 represent the arenaceous forms. 



STATION 286, lat. 68 11' S., long. 34 17' W. 



Depth 2488 fathoms; bottom temperature 31'3 F. A greenish-gray unctuous 

 glacial clay, gritty to the touch, containing 5 per cent, of lime. 



An insufficient quantity of the deposit was available for a complete estimation of 

 the Foraminiferal fauna. The only species found in the sample examined are
