hardly distinguishable, the surface then being neatly and smoothly finished. Otherwise 

 they are large and the surface is rough and angular. 



Fracture appears to occur always at or near the base of the chamber and not as might 

 be expected in the middle of the stolon tube. The separate chambers thus resemble a 

 Lagena with tapering neck, and bear considerable resemblance to the figures of Lagen- 

 ammina laguncula, Rhumbler (R. 191 1, FPE, p. 92, pi. i, fig. 4). Indeed, until the dis- 

 covery of the specimen with two chambers, these isolated chambers were assumed to 

 belong to that species, or to some allied form of Proteonina. I have no personal know- 

 ledge of Rhumbler's species, so cannot say how closely the specimens agree with his 

 types, which were from the North Atlantic at depths of 1524-2400 m.

One station: WS 334. 



One specimen from a depth of 3705 m. It is not perfect, but the characteristic thick 

 outer coating of sand grains is well preserved.

Two stations: 131 ; WS 33. 



Only a single small specimen at each station. 



Genus Hormosina, Brady, 1879 



108. Hormosina globulifera, Brady (F 89). 

 One station: WS 523. 



A few specimens only, mostly megalospheric single-chambered individuals. 



Genus Haplophragmoides, Cushman, 1910 



109. Haplophragmoides canariensis (d'Orbigny) (F 90) (Plate III, fig. 13). 



Thirty-nine stations: 13, 14, 15, 20, 27, 30, 31, 42, 45, 123, 126, 131, 140, 144, 148, 149, 157, 

 660; WS 25, 27, 28, 31, 32, 33, 40, 41, 42, 45, 46, 50, 63, 63-4, 154, 177, 348, 357; Drygalski Fjord; 

 MS 14, 68. 



Generally distributed in the shallower stations, almost entirely absent from deep water, 

 a depth of about 300 m. marking its limit with very rare exceptions, e.g. a single small 

 specimen at WS 63 in 1752 m. It is very common at Sts. 126, 144, 149, WS 28 and MS 

 68, and only less so at Sts. 27, 148 and WS 25, 32, 42 and 50. At the majority of the 

 stations, however, it is rare or very rare. The dominant type everywhere is an evolute 

 flattened form of normal size ; but, wherever the species is abundant, a much smaller
