rORAMINIFERA OF THE KEEIMBA AECHIPELAG-0. 661 



12 Stations. 



Occurs at mostStns., frequent. Common at Stiis. 1 and 7, where the best range of 

 individuals were obtained. The most typical specimens were at Stn. 12, where it Avas 

 less abundant. As usual there is a great deal of variation in the diameter of the 

 central portion of the test. At Stn. 9 some inequilateral specimens were observed 

 in which the shell is curved on one side of the long axis onl}% the other side being 

 straight from one aperture to the other.

15 Stations. 



Universally distributed, sometimes common; there is, as usual, a great range of 

 form and size. Perhaps the most noticeable variation is the occurrence at five or six 

 Stns. of a large form with coarse punctations covering the whole surface of the test, 

 except the central portion, running from the aperture downwards. This central 

 portion is quite clear and imperforate ; the marginal edge of this form is rather more 

 acute than usual. M Stns. 7 and 9, ■? X and ■? B a variety occurs with a broad and 

 almost caudate base. At Stn. 7 this variety occurs in a trigonal form. 



265. Lagena acuta (Reust^).

A few specimens only, presenting no abnormal feature, except at Stn. 7, where the 

 specimens had two well-marked spines at the base.
