28. M. sclerotica (Karrcr). (Eets., H-A. & E. 1915, F.K.A. p. 577.) Gene- 



rally distributed, and the same remarks as in the previous species

Common at Station I, where it presents a great range of variation 

 and attains a larg'j size. The largest .specimens are so flattened as 

 to be almost spiroloculine. II, III, VII, VIII, IX, v.r.

34. M. pulchejla (hicorr>u) var. e/egans Williamson (W. 1858, R.F.G.B. p. 88,

 striate variety of M. hicornis. (P. *) 



35. ,¥. 6o»ea7.'/ (dOrbiguy). (Refs., B. 1884, F.C. p. 173.) (P.*) Another

 even in dredgings. 



38. Massilina secans (d'Orbigny). (Eefs., B. 1884,'F.C. p. 167; and H-A.

42. Planispirina cliarensis Heron-Allen and Earland. (H-A. & E., C.I.
