This species is not uncommon at Funafuti. It appears to have 
been hitherto recorded only from localities in high latitudes. 
The Pacific specimens differ in no essential points from the 
northern form, as regards the carapace. 
From the sand of the Ist boring near the surface; from the 
lagoon dredgings, Rocky Islet (Sollas coll.). Also from dredgings 
off Funamanu, 50 fathoms; and off Tutanga, 200 fathoms 
(David coll.).

pt. ii. p. 188, pl. xxxiv. figs. 3 a-d. 
A characteristic valve of this species was found in the sand of 
the 2nd boring (Sollas) at 40 feet from the surface. It also 
occurred in the beach-sands at Avalau Islet (Sollas coll.).
