ASTRORHIZIDAE 57 



47. Crithionina mamilla, Goes (F 55). 



Two stations: 144; WS no. 



A single specimen, sessile on Hyperammina siibnodosa at St. 144, and another on a 

 stone at WS no, are the only certain records. A few doubtful specimens were seen 

 elsewhere, not worth recording. 



48. Crithionina pisum, Goes (F 56). 

 Four stations: 144; WS 27, 33; MS 14. 



Singularly rare. The only specimens recorded without hesitation as belonging to this 

 species were from St. 144, where several good examples were obtained. Spicules are 

 largely employed, with the usual fine sand, and it is not easy to state when the specimens 

 should be attributed to the type, and when to var. hispida. Two specimens from this 

 station which are otherwise typical are transfixed by very long spicules, which no doubt 

 serve the same purpose as the similar variation in Psammosphaera parva, viz. to support 

 the organism in the surface film of ooze. At the other stations the specimens are small 

 and obscure. 



49. Crithionina pisum var. hispida, Flint.

Crithionina pisum var. hispida, Heron-Allen and Earland, 1909, TNS, p. 410, pi. xxxiv, fig. 7. 



Two stations: 144; WS 27. 



Good specimens are frequent at WS 27, less typical at St. 144. 



Genus Dendronina, Heron-Allen and Earland, 1922 



50. Dendronina papillata (Heron-Allen and Earland) (F 59). 

 One station: 126. 



Two specimens in the youngest or "basal pad" stage. 



Sub-family PILULININAE 



Genus Bathysiphon, M. Sars, 1872 



51. Bathysiphon capillare, de Folin (Plate I, fig. 26). 



Bathysiphon capillare, de Folin, 1887, B, p. 276, pi. v, fig. 2 a-e; 1887, RR, p. 114, fig. 7 b. 

 Eight stations: 27, 45, 140, 144, 148; WS 33 ; Drygalski Fjord; MS 14. 



Fragments are not uncommon at most of the stations and very common at WS 33, but 

 there isonlyone approximately perfect specimen, at St. 45. This is regularly tapering and 

 curved and the apertural end rounded off, with a central opening. Total length 3-4 mm. 

 Maximum width 0-14 mm. The texture of the tube varies considerably, in some 

 specimens fine sand grains are liberally used, in others only fine mud. The wall is un- 

 pohshed, thin and frequently collapsed.
