rORAMINIFEEA OF THE KERIMBA AECHIPELAGO. 731 



2 Stations. 



Two typical specimens at Station 11, and one weak but recognizable individual at 

 Station 3. The rarity of this form is noticeable as the records of its distribution ar-" 

 cosmopolitan ; it is, however, in our experience, much more abundant in high latitudes 

 tlian in tropical gatherings.

17 Stations. 



Generally distributed and usually fairly abundant. There is as usual a consider- 

 able range of variation, but all the forms are of the compressed type, ranging from 

 the highly compressed and complanate N. gratelouin d'Orbigny (d'O. 1889, FC. p. 40, 

 pi. vi. figs. 6, 7, N. gradeloupi) through the more turgid N. sloumi (ibid. p. 4ti, pi. vi. 

 fig. 18). None of the turgid N. lahradorica Dawson, type (Canad. Nat. vol. v. 1860, 

 p. 191, fig. 4) were observed. This last variety appears to be confined to cold-water 

 records. 



At Stns. 1, 4, and 6 specimens were observed closely approaching N. boueana ; at 

 Stn. 2 many of the specimens were near the inequilateral N. turgida.
