FORAMINIFERA— HERON-ALLEN AND EARLAND. 93 



large and coarsely built. At Station 55 a large broken specimen, largely built up of 



spicules, is apparently referable to Cuskman's Proteonina ovata (C. 1910, etc., 



FNP. 1910, p. 43, fig. 43). 



[The many varied forms of this species are isomorphic with the hyaline 



series Lagena apiculata (Rss.) to L. laevis (Mont.).]

 A single specimen.

Millett, 1898, etc., FM. 1899, p. 25.3. pi. iv., fig. 11. 



Stations 6-10, 13, 16, 25, 27, 29, 32, 38, 40, 41, 44, 47, 48, 50, 51 (+ D.). 



Widely distributed, but as a rule represented by few and imperfect specimens. 

 This is a species which frequently exhibits a selective tendency, usually for 

 mica. It is worthy of note that Williamson's original coloured figure uncon- 

 sciously records this fact. Micaceous building was observed at Station 8. At ' 

 Station 29, mica and garnets are used indifferently, at Station 44 garnets only. 

 The best specimens occur at Stations 27, 29, 32 and 40.

Generally distributed, but usually rare, increasing in abundance towards the 

 south, the best Stations being 44, 47, 48, 50, 53 and 54. At all these Stations 

 the specimens are very dark in colour, owing to the predommance of basaltic 

 sand, contrasting strongly with the quartz-built specimens from the northern 

 Stations.

Station 6 ( -f D.). 



A single specimen with produced neck, constructed of fine sand-grains.
