The specimens are all minute, and although they occur at most of 
the Stations, are not very numerous. 
Eaplophragm ium ayglutinans var. triperforata var. n., 
plate Y. figs. 2, 3. 
Having the general form of the type, this varies in two respects ; 
the shell wall, instead of being rough through the coarseness of the- 
incorporated sand-grains, is smooth as in the genus Trochammina ; 
this smoothness however does not arise from an excess of cement, 
but from the fineness of the material employed. In place of the 
simple aperture there are always three perforations with raised 
borders, arranged in the form of a triangle. As shown by fig. 3„ 
these perforations exist in the spiral as w T ell as in the uniserial 
chambers. The interior is quite smooth and not at all labyrinthic ; 
hence its affinities seem to be with Eaplophragmium rather than 
with Lituola. It is not uncommon at Station 9, and occurs also, 
but very sparingly, at Station 5. 
Its nearest ally appears to be the E. lituolinoideum of Goes from 
the Gulf of Mexico.* 
Eaplophragmium pseudospirale Williamson sp. 
Proteonina pseudospiral is Williamson, 1858, Rec. Foram. Gt.

spirale (Will.) Balkwill and Wright, 1885, Trans. R. Irish Acad. r

spirale (Will.) de Amicis, 1895, Naturalista Siciliano, Anno xiv. p. 9, 
pi. i. fig. 11. 
The typical form with obscure segmentation is rare, but at several 
of the Stations there are numerous examples which have the sutures 
well marked, and which differ from E. ayglutinans only in the com- 
pression of the test. Of the figures by Goes referred to above, 148 
and 149 represent this form. 
In the ‘ Challenger ’ Report the only localities given by Brady 
for this species are about the coasts of the British Isles ; but in the 
‘ Summary of the Scientific Results ’ it is reported from Station 172a. 
(Tongatabu). The Gazelle Station is off West Australia.
