the beach-sands at Fualopa Islet, at Avalau Islet, and in the 
lagoon dredgings from Rocky Islet (Sollas coll.); also in the 
lagoon dredgings sample 18, 9 miles from the Mission Church, at

The specimens from Funafuti are not very typical, but are 
apparently immature. In some points they resemble Cythere 
pectunculata, sp. nov., especially in the strong tubercles seen 
ou the surface of the valves. Dr. Brady reports it as common 
among the South Sea Islands. 
C. prava was found at Funafuti in the samples of sand from 
the 1st boring in the Atoll, near the surface; and in the beach- 
sands of Fualopa and Avalau Islets (Sollas coll.).

p. 501, pl. i. figs. 17, 18. 
This species, which was originally described from specimens 
obtained by Dr. Brady from New Caledonia and Samoa, was 
found at one locality only at Funafuti, off Funamanu, 50 fathoms. 
The Funafuti specimen is typical but small, and is probably a 
young example.
