CyMBALOPORA PoryI, var. sqguAMOSA (d’Orb.). 
Rotaha squamosa, d’Orb., 1826, Ann. Sci. Nat. vol. vii. p. 272. no. 8. 
Rosalina squamosa, d’Orb., 1839, Foram. Cuba, p. 100, pl. iii. figs.

Cymbalopora Poeyi, d’Orb., depressed var., Brady, 1884, Rep. Chall. 
vol. ix. p. 637, pl. cii. figs. 14 a-d. 
This variety is a neat depressed form of the heavier sub- 
conical specific type; in its earlier stages it is sometimes found 
parasitic upon alge. 
DIscoRBINA ACUMINATA, sp.nov. (PI. 36. fig. 3.) 
Test conical, elongate; the apex terminating in a sharp point. 
The inferior face deeply sunken. Chambers arranged in about 
six whorls, the segments long and set obliquely. Surface of test 
ornamented with radiating striz centred in the apex and the 
umbilicus respectively. Height -3 mm.; diameter -2 mm. 
Although D. acuminata is related to D. tabernacularis, Brady, 
it differs in having straighter and longer sides to the cone and a 
pointed aboral extremity. 
Shore-sand, Avalau Islet, Funafuti; rare. 
PLANORBULINA RETINACULATA, Parker & Jones. 
Planorbulina retinaculata, P. & J., Phil. Trans. vol. cly. 1865, p. 380, 
pl. xix. fig. 2. 
A wild-growing modification of P. mediterranensis, d’Orbigny, 
parasitic on shells or alge, in which the chambers of the later 
whorls are partially separated, and bear numerous apertures 
especially around the periphery of the test. Parker and Jones’s 
specimens were found in the West Indies. This form is especially 
worthy of notice, as it does not appear to have occurred often, 
if at all, since the original description was published. P. retin- 
aculata occurs at Funafuti detached from their surfaces of 
support and mingled with the sand. 
CaLCaRINA SPENGLERI (Linné). 
This species appears to be almost exclusively confined to the 
East Indian Archipelago, and therefore its occurrence at Funafuti 
in at least one of the samples of beach-sands is interesting as 
adding to its geographical range. The Funafuti specimens are 
small but typical,
