IlahitiU. — Station 23G, off south of Japuu, in 775 fathoms; and Station 311, off the 

 west coast of Southern Patagonia, in 245 fathoms. 



A single crushed specimen, about 2 inches in length, from the former locality, and a 

 rather smaller odd valve from the latter, are all that were obtained. Whether this species 

 1)6 really distinct or not from the Norwegian Lima excavata of Fabricius I cannot decide, 

 but Mr. Sowerby, who has a very accurate appreciation of differences, is of opinion that 

 it is different. The Challenger valves are almost smooth down the middle, and the 

 lateral strise are finely punctate, whilst Norwegian examples are striated at the centre, 

 and the lateral sulci are not punctured in the same manner. 



It is very curious that Japan and South Patagonia should furnish apparently the 

 same species.

Habitat. — Levuka, Fiji Islands, in 12 fathoms (Challenger). 



This species is very like the West Indian Lima scahra, but is more finely sculptured. 

 Both are equally variable in form. In the British Museum there are specimens from the 

 Island of Narai, Fijis, collected at low water by Macgillivray, from Sir C. Hardy's Island 

 (Jukes), and from Port Essington. Other localities are Zanzibar (Mus. Cuming) ; 

 Bourbon, Reunion, and Mauritius (Martens) ; Philippine Islands and Singapore 

 (Sowerby).

Habitat. — Station 36, off Bermuda, in 30 fathoms ; coral. 



The recent and fossil distribution of this species has been given by Jeffreys, but he 

 has not recorded it from the West Atlantic region.
