material. I have indicated with an asterisk in the Station List the thirty-nine station 

 slides which he prepared. He also, in association with Dr Helene Bargmann, made the 

 preliminary working index of species from my identifications of the station slides. To 

 Herr Hans Wiesner I am indebted for confirmation of the identity of several species 

 common to both Discovery and Gauss material, and to Dr L. Rhumbler for information 

 respecting his genus Astrammina. Dr J. A. Cushman of Sharon, Mass., Mrs H. J. 

 Plummer of Austin, Texas, and Mr W. J. Parr of Melbourne have helped by supplying 

 paratypes, and other specimens required for purposes of comparison. Dr Hans E. 

 Thalmann of Berne has kindly scrutinized the list of new species for homonyms. 



The station slides, types and all other preparations are deposited in the Heron-Allen 

 and Earland collection at the British Museum (Natural History). 



A list of the stations worked over is as follows : 



STATIONS MADE BY THE R.R.S. 'DISCOVERY' 



161. TS 631.1 Fig. I, F 1.2 



14. ii. 27. 57° 21' 20" S, 46° 43' 30" W. Sounding, 3459 m. 



Only a few grains of coarse sand yielding single examples of five recognizable genera of Fora- 

 niinifera, including a specimen of Hastigerina pelagica, the only record from the Antarctic material 

 examined. 



162. TS632. Fig. I, F II. 



17. ii. 27. Off Signy Island, South Orkneys, 60° 48' S, 46° 08' W. Sounding, 320 m. 



About 20 cc. dark olive-brown mud which left a residue of less than i cc. on 200-mesh silk, 

 composed of mica, diatoms and a few Foraminifera. Only ten species were recorded, Miliammina 

 arenacea, Virgulina schreibersiana and CassiduUna a'assa being dominant, the other species, of no 

 particular interest, being very rare. 



163. TS633. Fig. I, F II. 



17. ii. 27. Paul Harbour, Signy Island, South Orkneys. Debris from small beam trawl, i8-27m. 

 About 30 cc. of algal, zoophyte and crustacean debris, without fine material. Rich in diatoms, 



it contained very few species of Foraminifera, mostly represented by single specimens, Haplo- 

 phragmoides canariensis alone occurring with any frequency. Among the rarities were Iridia diaphana 

 and Hippocrepina oviformis. 



164. TS634. Fig. I, F II. 



18. ii. 27. East end of Normanna Strait, South Orkneys. Small beam trawl and coarse silk nets 

 attached to trawl, 24-36 m. 



The residues from the trawl consisted of a small quantity of crustacean, annelid and sponge 

 debris, with diatoms which formed a felted mass. There were few species of Foraminifera and none 

 of the larger forms. The nets furnished about 40 cc. of fine grey mud. CassiduUna crassa and C. 

 subglobosa were the only common species. Among the few rarer forms were Hippocrepinella hiriidinea, 

 Iridia diaphana and Discorbis parisiensis. 



167. TS 635*, 636. Fig. I, F II. 



20. ii. 27. Off Signy Island, South Orkneys, 60° 50' 30" S, 46° 15' W. (a) Sounding, 344 m.; 

 (b) small beam trawl with various nets attached, 244-344 i^-

 the Natural History Museum. An asterisk after a number indicates that the particular station slide was 

 mounted by Mr E. Heron-Allen.
