Extremely rare. The specimens poor and tending towards S. planulata. As a recent 

 British form, it has only been recorded by us from Selsey Bill and Clare Island (H.-A. & 

 E. 1908, etc., SB. 1911, p. 302; and 1913, CI. p. 24).

2 Stations, 



Extremely rare, but one comparatively large and typical specimen occurred at Stn. 20. 

 We have recorded it as an Eocene fossil from Selsey Bill (H.-A. & E. 1908, etc., SB. 

 1909, p. 311). 



11. Spiroloculina excavata, d'Orbigny.

Widely distributed and common at many Stns., attaining extremely fine development 

 at Stns. 10, 18, 19, and 20. 



12. Spiroloculina planulata (Lamarck).

 Spiroloculina planulata, Brady, 1884, FC. p. 148, pi. ix. fig. 11 a, b. 



14 Stations. 



Fairly widely distributed, but not so abundant as S. excavata. A very fine series at 

 Stns. 10 and 18; there is, as usual, a tendency to run into S. dorsata on the one hand 

 and S. excavata on the other. At Stn. 15 a series of specimens running entirely into 

 S. excavata. 



13. Spiroloculina dorsata, Eeuss. (New to Britain.)
