64 "TERRA NOVA" EXPEDITION. 



Stations 6, 8. 10. 13. 16. 17. 23. 36(+T. d.F., E. d. J.). 



As usual, it is practically impossible to separate this form from Miliolina 

 pygmaea, but we are recording the spiroloculine forms separately for taxonomical 

 reasons. In both the N.Z. and Antarctic areas it occurs in two distinct forms, 

 porcellanous and sub-arenaceous. The two occur together at Station 6, where it 

 is best represented, and at Stations 16 and 17. The porcellanous form occurs alone 

 at Station 8 (N.Z.), and 13 (Ant.), where the individuals are exceptionally long. At 

 tlie other Stations only the sub-arenaceous type occurs, the . finest specimens 

 Ijeing found at Stations 16 and 36.

In the N.Z. area the specimens are, as a rule, very small^ the best at Stations 

 1, 5 and 6. In the Antarctic the best series and the most abmidant occur at the 

 most southerly Station. 55, where it is well developed. At the other Stations it 

 is extraordinarily variable in development and frequency, ranging from single 

 small individuals to large (at Station 31) and one exceptionally large (fragmentary) 

 at Station 37.
