FROM THE LAGOON AT FUNAFUTI. 171 
SPIROLOCULINA NITIDA, d’Orbigny, var. FOvEOLATA, Egger. 
(Pl. 19. fig. 4.) 
Spiroloculina foveolata, Egger, 1893, Abhandl. bayer. Akad. Wiss., 
math.-phys. Cl. ii. vol. xviii. p. 224, pl. i. figs. 33, 34, 
Sprroloculina nitida, d’Orb. (reticulate variety), Millett, 1898, Journ. 
R. Mier. Soc. p. 266. 
This is a very interesting variety which has been recorded from 
the Mauritius, the Malay Archipelago, and the S. Pacific. It is 
well developed at Funafuti, but in the external form perhaps 
more nearly resembles S. planulata (Lam.). 
Lagoon, Funafuti; common. Sample 18 (74 fathoms). 
SPIROLOCULINA TORTUOSA, sp. nov. (PI. 19. fig. 5.) 
This curious form somewhat resembles S. lamella of Egger *, 
but is more regular in shape, and is of the S. ewcavata type. The 
sutural edges of the central series of chambers are strongly con- 
torted. The extremities of the test resemble those of S. impressa, 
Terquem. Length ‘6 millim. 
Lagoon, Funafuti; frequent. Sample 5 (24 fathoms); sample 
15 (19 fathoms); sample 17 (12 fathoms). 
SPIROLOCULINA ANTILLARUM, d’ Orbigny. 
Spiroloculina antilarum, VOrbigny, 1839, in Sagra’s Cuba, Foram. 
p- 149, pl. xi. figs. 3, 4. 
The ‘Challenger’ collections yielded this species from only 
one station in the S. Atlantic, at 350 fathoms. 
Jt is rare at Funafuti, and appears to be nearly related tojthe 
form S. grata, Terquem. 
Lagoon, Funafuti; rare. Sample 18 (74 fathoms). 
SPIROLOCULINA G@RATA, Terquem. 
Spiroloculina grata, Terquem, 1878, Mém. Soc. Géol. France, sér. 3, 
vol. i. p. 55, pl. x. figs. 14, 15. 
S. grata, Terq., Egger, 1893, Abhandl. bayer. Akad. Wiss., math.- 
phys. Cl. ii. vol. xviii. p. 224, pl. 1. fig. 39. 
This is one of the most frequent species of the genus in 
shallow-water sands of the coral-reefs. The specimens found 
here are typical in form and size.
