SYSTEMATIC ACCOUNT 35 



At Sts. 312, 313 and 417 the smooth form attains a large size, and the normal aperture 

 is subdivided by bridges across the slit, as is often the case with large apertured species. 

 It is the Cribrostonioides bradyi of Cushman, but I am convinced from a long study of 

 the species in the Haplophragmium oozes of the Cold Area of the Faroe Channel that it 

 is only an advanced stage of growth of H. subglobosus. 



Pearcey's records are not easily understood. Of the type he says that it occurs at 

 Sts. 300, 313, 416, 417, 418, 420, 447, "but nowhere common". He records Cribro- 

 stonioides bradyi, Cushman, separately as "rare" at Sts. 313, 418, 420. 



72. Haplophragmoides glomeratus (Brady) (SG 114) (A 167). 

 Six stations: 226, 301, 303, 312, 313, 417. 



Frequent at St. 417; rarer at Sts. 312, 313 where the specimens were large; very rare 

 elsewhere. 



Pearcey: 420 "rare". 



73. Haplophragmoides rotulatus (Brady) (SG 115) (A 168). 

 Four stations: 312, 313, 406, 417. 



Very rare, except at St. 406 where the specimens are rather more numerous, smaller 

 and less coarsely constructed than at the other stations. None of them can be regarded 

 as quite typical. 



Pearcey: 337 A "few", 342 "rare". 



Genus Recurvoides, Earland, 1934 



74. Recurvoides contortus, Earland (A 169) (Plate I, figs. 20-22). 

 Eight stations: 300, 301, 303, 313, 394, 406, 417, 421. 



Rare everywhere except at Sts. 406, 417 where the species is not uncommon and a 

 good series was obtained; less frequent at St. 313. These three stations are in shallower 

 water (1131-1775 fathoms) than the others, which all lie near the 2500 fathom line. 



Pearcey's records of Haplophragmoides scihdiis (No. 69) probably included this 

 species. He also records Trochammina turbinata (Brady) at Sts. 300, 447 "rare". This 

 is hardly likely to have been Brady's species (see A, p. 91) but may have been Recurvoides 

 contortus. 



Genus Ammobaculites, Cushman, 1910 



75. Ammobaculites agglutinans (d'Orbigny) (F 96) (SG 116) (A 170) (Plate I, figs. 



23, 24). 



Five stations: 303, 309, 313, 406, 417. 



Large specimens are frequent in the trawl washings from Sts. 313,417; single smaller 

 individuals in the soundings from the other stations. As a rule specimens have only 2-3 

 chambers in the extended series, but typical many-chambered examples occur at 



St. 313. 



Pearcey: 337 a, 338, 342, 447 "nowhere very abundantly".
