DiscorBINa TUBEROCAPITATA, Chapman. 
Discorbina tuberocapitata, Chapman, 1900, Journ. Linn. Soc., Zool. 
vol. xxviii. p. 11, pl. i. figs. 9 a-c. 
This striking form is not so well developed in the lagoon 
samples, as in the shallow-water dredgings on the outer part of 
the reef. 
Lagoon, Funafuti. Sample 11 (25 fathoms); sample -13 
(26 fathoms); sample 16 (20 fathoms). 
DISCORBINA RARESCENS, Brady. 
Discorbina rarescens, Brady, 1884, Rep. Chall. vol. ix. p. 651, pl. xe. 
figs. 2, 3, and 4? 
D. rarescens, Brady, Egger, 1893, Abhandl. bayer. Ak. Wiss., math.- 
phys. Cl. ii. vol. xviii. p. 388, pl. xv. figs. 45-47. 
The species which have undoubtedly lived in the lagoon are 
not numerous, and apparently the present form is an example 
which has adapted itself to those conditions. It appears to grow 
attached to the surfaces of other organisms such as Halimeda. 
Brady records this species from the Philippines and Torres 
Strait, and Egger from West Africa and Western Australia. 
Lagoon, Funafuti. Sample 4 (3 fathoms); sample 6 
(21 fathoms) ; sample 18 (26 fathoms); sample 14 (16 fathoms), 
sample 16 (20 fathoms); sample 17 (12 fathoms).

1897, p. 828, pl. 72. fig. 6. 
This species has a wide geographical distribution. It has 
already been recorded from the Pacific Ocean. The lagoon 
specimens are small and arrested in their growth, and are very 
like the specimen figured by Goés to which reference is given 
above. 
Lagoon, Funafuti. Sample 1 (10 fathoms); sample 18 
(26 fathoms); sample 18 (73 fathoms).
