 at both Stations.

Stations 23, 25, 26, 28, 29, 32, 33, 35, 37, 38, 40, 48, 55 ( + T. d. F., D.). 



Confined to the Antarctic and represented as a rule Ijy fragments. The best 

 specimens at Station 28. At Station 29 some good specimens, which probably 

 represent a dentaline microspheric form, characterized by a large number of 

 chambers. They suggest R. bacillaris, Brady, but differ in the comparatively 

 coarse construction of the test. At Station 37 a small specimen, consisting of 

 three chambers, very thin-walled, almost chitinous, isomorphous with Nodosaria 

 soluta.

Reophax spiculifera, Brady, 1879, etc., RRC. 1879, p. .5-1, pi. iv, figs. 10, 11.

Stations 2, 3, 4, 6, 27, 41, 52. 



At a few Stations only in both areas. The Antarctic records rest on three 

 Stations. At Stations 41 and 53 Brady's origmal type occurs, very well grown. 

 The specimens from the N.Z. area pre.sent far greater variety and indicate that 

 they do not represent a true species but are merely spiculiferous isomorphs of 

 various Nodosariae. They are most abundant at Station 6, where they attain a 

 large size and range in form between isomorphs of Nodosaria fUformis, communis, 

 and soluta. At this Station also the species occurs sessile and adapting itself 

 to the contour of the object to which it is attached, isomorphous with Nubecu- 

 laria tibia, Jones & Parker. Similar wild growing isomorphs of N. lucifuga, but free, 

 occur at Station 2. 



At Stations 2, 3 and individuals occur with long separating stolon-tubes, 

 referable to Cushman's var. jjseudodistans (C. 1919, RFNZ. pi. Ixxv, fig. 1;, but in 

 our opinion these would have been better described as spiculiferous specimens 

 of R. distans, Brady. At Station 6 one of the individuals was sessile.
