FORAMINIFERA OF THE FUNAFUTI ATOLL. 409 
Affinities.—Vhe nearest allied form to this species is H. cal- 
careum, Brady *, but the latter has the initial portion of the test 
more inflated, and is composed of irregular calcareous particles. 
The test in H. tesselatwm is formed of angular chips cemented 
by a harder substance which stands out in relief above the frag- 
ments themselves. 
Off Funamanu, 50 fathoms ; very rare. 
GAUDRYINA ATTENUATA, sp. nov. (PI. 36. fig. 10.) 
Test elongate, somewhat sinuate or twisted; commencing with 
a sharply triangular series of chambers arranged triserially, 
followed by an irregular textularian arrangement, and finally by 
two or three pairs of subglobular chambers. Length of test 
about 1°3 mm. 
Affinities.—This species is not unlike G. baccata, Schwager +, 
but differs in having an acutely angular commencement, and the 
test is much more attenuate. 
W. of Tutauga, 35 fathoms; rare. 
GAUDRYINA ROTUNDA, sp. nov. (Pl. 36. figs. 11 a—c.) 
Test short and stout or subrotund; the earlier triserial chambers 
are subglobose, and these are quickly followed by subglobose 
chambers slightly flattened laterally and arranged in a biserial 
manner. Aperture a crescentic textularian slit. Shell-wall 
arenaceous, somewhat coarse in texture and whitish. Len oth of 
test about 2°2 mm.; greatest width 2 mm. 
At a first glance this species might be taken for Verneuwilina 
propingua, Brady £, which, however, is distinctly biserial in the 
later part of the shell. 
This species was found only at one locality, and the specimens 
in point of size are all much alike. 
Off Tutanga, 200 fathoms ; frequent. 
BiraRina LimBata (Brady). (PI. 36. fig, 12.) 
The general tendency of this species as it occurs at Funafuti 
is, when fully developed, towards the dimorphous genus Bifarina. 
It has the later chambers arranged in a uniserial manner, and 
they are connected internally by a siphonate tube, terminating 
in a phialine aperture. The general arrangement of the test 
in our specimens is less distinctly textularian than in the
