p. 303, pi. 17. figs, 5-7). Large, very common. Also a small 

 thick variety with angular margin, not outspread as in the 

 typical form : this possibly may only be an immature stage of 

 H. depressa ; but it is very common. 



50. Operculina complanaia, Defrance, sp. (1822, LenticuUtes corn- 

 planata, Diet. Sci. Nat. vol. xxv. p. 453). Medium size, rare. 



This thick Operculina, common in the Eed Sea, Indian 

 Ocean, and Australia, is not the typical 0. compJanata, but 

 rather an intermediate form, showing the close relationship to 

 ■ Nummulina planulata. 



51. Operculina granulosa, Leymerie (1846, Mem. Soc. Geol. France, 

 ser. 2, vol. i. Mem. no. 8, p. 859, pi. 13. fig. 12, a-c). Not 

 uncommon. 



52. Nummulina planulata, Lamarck, sp. {LenticuUtes planulata, 



Lamarck, 1804; Ann. Mus. p. 187. no. 1). Medium, rare. 



When at Cagliari in 1871, I obtained a small quantity of 

 the foraminiferous sand found in the neighbourhood of the
