Tn one instance only the valves from Funafuti show indications 
of a posterior spine; otherwise they resemble the most typical 
specimens. Dr. Brady has lately described this species trom 
Nouméa, and from the reef at Apia, Upolu.. 
At Funafuti this species was found in the beach-sand at 
Avalau Islet (Sollas coll.); in the lagoon dredgings, sample 18, 
9 miles from the Mission Church, 73 fathoms (David coll.) ; off 
Funamanu, 150 fathoms, and off Tutanga, 50-60 and 200 fathoms 
(David, Halligan and Finckh coll.).

The type specimens were found in anchor-mud, at 4 fathoms, 
Sava-Sava, Fiji. 
Characteristic valves were found at Funafuti in the beach- 
sand, Avalau Islet (Sollas coll.); and in dredgings, N. of Pava, 
32 fathoms, and off Tutanga, 200 fathoms (David, Halligan and 
Finckh coll.).

ARGILL@CIA AFFINIS, sp. nov. (Pl. 37. figs. 1 a—c.) 
Carapace oblong, somewhat compressed, subpyriform; height 
less than half the length. In side view the anterior extremity 
obhquely rounded; posterior produced, with the ventral angle 
subacute. Dorsal margin slightly arched, or nearly straight, 
especially in the middle third, sloping sharply backward to the 
ventral angle. Ventral margin slightly sinuate, hollow in 
the centre. Edge view subovate, acuminate in front, rounded 
behind; width equal to the height. Hnd view nearly circular. 
Shell-surface polished, and seen to be faintly pitted, when 
viewed with a high power. Length of carapace ‘66 mm. 
This species is most nearly allied, in the form of the carapace, 
to A. acuminata, G. W. Miiller*. The specimen was not
