6-2 "TEREA NOVA" EXPEDITION. 



after him. B. bradyL by Schluniberger (8. 1891. BGF. p. 170, text figs. 15-19, pi. x, 

 figs. 03-71). None of the specimens show the transverse ridges of sliell-matter 

 figured l)y Schluniberger. but not appearing in Brady's original figure, or Chap- 

 man's (C, 19U. F0K8. p. ",. pi. 1. fig. 1: and C. 1909. 8XZ. p. 314. pi. xiii. 

 fig. 1).

Stations 1, 4, 8, 10-12. 



N.Z. area only. The species attains a comparatively large size, especially at 

 Stations 10 and 11. The individuals differ from Brady's type, whicb may be 

 regarded as a striate form of B. ringens and B. bulloides. The N.Z. specimens 

 are closely allied to B. lucernula, Schwager, the produced tubular neck attaining 

 noticeable dimensions at Stations 10, 11, 12. The only individual of Brady's 

 type observed was at Station 1. 



Judging by the recorded figm-es of Flint, Cushman and Schlumberger, B. 

 comata is normally a striate variant of B. ringens and B. buUoules ; the 

 occurrence of similar surface ornament in another type, and prevalent in a 

 particular area, is an interesting feature. 



12. Biloculina elongata, d'Orbigny. 



Biloctdina elongata, d'Orbigny, 1826, TMC. p. 298, no. 4. 



Heron-Allen and Earland. 1914. etc. FK.V. 1915, p. 552. 



Stations 19, 26, 38. 46, 47 (+ K. I., R. d. J.). 



Rare and confined to the Antarctic area. Large and quite typical specimens at 

 Stations 46, 47 and 48. 



13. Biloculina depressa, d'Orbigny.

Stations 1-6, 8, 10, 12, 17-20, 23, 27, 38 (+ K. I.. D.). 



The species reaches its maximum development, both as to numbers and size, 

 at Station 6. At Stations 8 and 10 the individuals are fimiished with a broad keel. 

 In the Antarctic area it is much less frequent, and the specimens do not attain the 

 development of the N.Z. forms. 



14. Biloculina depressa, var. nmrrhynu, Schwager. 



Bilocnlina murrhyna, Schwager, 1866, FKN. p. 203, pi. iv, figs. 15a, b.

Stations 10-12, 17, 18, 19, 36 (+ T. d. F.). 



Occurs in company with the type at several Stations, but at others the type is 

 not represented. Maximum development at Station 11 (N.Z.), the Antarctic speci- 

 mens are much weaker, and few in number.
