One station: 170. 



Two very fine specimens, one megalospheric and the other microspheric, were found 

 at St. 170, Clarence Island, 342 m.

Nodosaria raphanistrum, Heron-Allen and Earland, 1922, TN, p. 171. 



Three stations: 384-6. 



Extremely rare at these stations, which are all in the deep water of the Drake Strait. 



The small form figured has little in common with the gigantic specimens found in 

 some of the European tertiary deposits, which attain a length of more than an inch. But 

 they have the really specific feature in their approximately equal diameter throughout, 

 and the discontinuous but parallel costae. The largest specimen, found at St. 384, has 

 six chambers, but most of the others only three or four. They all agree in having a 

 proloculus wider than the subsequent chambers, and a final chamber narrower than its 

 predecessor and with a truncate extremity bearing a very small central aperture. This 

 last feature marks their pauperate condition. 



It would no doubt have been possible, given the time, to find a figure more or less 

 resembling the specimens among the hundreds of illustrations available ; or failing that 

 to add yet another species to the already swollen list of Nodosariae. But I regard them 

 merely as highly pauperate individuals, and have listed them under the zoological species 

 to which I think they belong. 



Length of a four-chambered specimen 0-36 mm. 



N. raphanistrum was recorded by the Terra Nova Expedition from the New Zealand 

 area and from the Antarctic (H.-A. and E. 1922, TN, p. 171, no. 403). The New Zea- 

 land specimen was typical, but those from the Antarctic stations 23, 27, 36 were identical 

 with the Discovery specimens. It would therefore appear that this pauperate form is 

 widely distributed in southern waters. 



Genus Lingulina, d'Orbigny, 1826 



422. Lingulina vitrea, Heron-Allen and Earland (F 264) (SG 258). 



Two stations: 175, 190. 



Two typical specimens at St. 190 to the south of the Palmer Archipelago, in 130 m., 

 and a single specimen at St. 175 in the Bransfield Strait, 200 m. This last-mentioned 

 specimen is far from typical, the four chambers following the proloculus increasing in
