2:u "TERRA NOVA ' EXPEDITION. 



Quarters, 4 hole, 41 fnis. ; at 12 hole on Sept. 8, 1903, no depth stated ; and at 

 6 liolc on Jan. 14, 1903, 130 fms. 



All the specimens are similarly built of fine dark grey mud with very long 

 slender sponge-spicules ii-regularly projecting. Many of these spicules project half 

 an inch or moie. They are not sufficiently numerous to bring the specimens into 

 any resemblance to Crithionina piswm, Goes, var. Mspida, Flint. Miliolina circu- 

 lar is (Born.) was built into one specimen. 



One of the specimens given to us was a fragmentary worm-tube from Winter 

 Quarters, 6 hole, 130 fms. (Jan. 14, 1903, 77° 50' 30" S. ; 166° 44' 45" E.) This 

 was carefully broken up and yielded many species of Foraminifera. 



The tube of mud bore the label, Station 270, March 4, 1904, 254 fms. (67° 

 21' 46" S. ; 155° 21' 10" E.). This, having been washed, yielded about 2 c.c. of 

 material which was relatively rich, giving us 104 species and varieties which we 

 have indicated in our Report by the letter " D," after the list of Stations for 

 recorded species. 



Among these were eight that did not occur in the " Terra Nova " material, 

 as follows : — 



G44. Hippocrepina indivisa, Parker. 



Hijjpocrejjiiia indivisa, Parker, 1870, GStL. p. 176, fig. 2. 



Heron-AlU-n and Earland, 1913, CI. p. 48, pi. ii, figs. 10, 11. 



A small broken individual, lacking the oral extremity, but undoubtedly refer- 

 able to this species. Very thin-walled, constructed of extremely fine mud with 

 ferruginous cement, deep rust-colour at the aboral point, fading into grey at the 

 broken end. Hippocrepi'TM has hitherto been regarded as an exclusively boreal 

 form, and its southern limit, so far, has been in the Moray Firth. Its occurrence 

 even as a single specimen is therefore extremely noteworthy. 



644a. Reophax guttifera, Brady. 



Reofliax guttifera, Brady, 1884, FC. p. 295, pi. xxxi, figs. 10-15. 



Cusliman, 1910, etc., FNP. 1910, p. 88, fig. 123. 



A single typical specimen. 



645. Bolivina textilarioides , var. arenacea, nov. PI. IV, figs. 29, 30. 



Excellent isomorphs with characteristic bolivine aperture, built up of fine 

 grey and black mineral particles. Many specimens, in some cases having as many 

 as nine and ten pairs of chambers. One individual attached Ijy its aperture to 

 a large sand-grain by means of cement. 



Size: — Length, •20--30mm. ; maximum breadth, -ISnmi. 



646. Bolivina variabilis, var. arenacea, nov. PI. IV, figs. 27, 28. 



A single specimen, characterized by obscure septation and evenly continuous
