SYSTEMATIC ACCOUNT 37 



Genus Tolypammina, Rhumbler, 1895 



84. Tolypammina vagans (Brady) (F 100) (SG 125) (A 180). 

 Two stations: 422, 428. 



A few specimens sessile on pebbles or large sand grains at each station. 

 Pearcey: 291, 417, 420 "fine typical specimens of a dark greyish-brown colour". 



Genus Ammodiscus, Reuss, 1861 



85. Ammodiscus incertus (d'Orbigny) (F loi) (SG 126) (A 181). 

 Three stations: 226, 301, 312. 



Only a single very small specimen at each station. Its rarity is rather curious as the 

 species is so universally distributed. 

 Pearcey: 337 a "sparingly". 



Genus Glomospira, Rzehak, 1885 



86. Glomospira gordialis (Jones and Parker) (F 102) (SG 127) (A 183). 

 Five stations: 226, 290, 295, 303, 422. 



Very rare everywhere. Free growing individuals at Sts. 303 and 422 ; both free and 

 sessile at St. 295 ; sessile only at Sts. 226 and 290. 

 Pearcey: 342 "sparingly". 



87. Glomospira charoides (Jones and Parker) (F 103) (SG 128) (A 184). 

 Twelve stations: 286, 290, 295, 300, 301, 303, 312, 313, 417, 428, 432A, 438. 



Fairly frequent considering the poverty of the material at Sts. 312, 428 and 432 a; at 

 the last station ten small specimens were found, more than the number of specimens of 

 all the other species present. Never more than two specimens at the remaining stations, 

 all very small except two of normal size at St. 3 13. This is evidently one of the essential 

 species of the glacial muds and clays. 



Pearcey: 342, 416, 447 "not in any abundance". 



Genus Trochammina, Parker and Jones, i860 



88. Trochammina squamata, Jones and Parker (F 104) (SG 131) (A 188). 

 Two stations: 295, 417. 



A single specimen at St. 295 ; large, typical and frequent at St. 417, where one sessile 

 individual was also found. 



89. Trochammina inflata (Montagu) (F 108) (SG 134) (A 191). 

 Two stations: 303, 417. 



A single specimen at each station. 



90. Trochammina malovensis, Heron-Allen and Earland (F 109) (SG 135) (A 192). 

 Five stations: 286, 312, 313, 338, 406. 



Extremely rare everywhere.
