obtained it at three stations off the S. W. coast of Portugal, 292 — 718 fm. ("Fragments of old and 

 young specimens. Semifossil?"). 



Next, it is mentioned by Dautzeuberg and Fischer (I.e.) from the Azores, 595 — 900 fm. and 

 by Locard (I.e.) W. of Soudan, 335 — 1380 ftn. x ) 



It is found as postglacial fossil in Norway, up to a size of 160 mm . 2 )

The "Ingolf" has taken this species at: 



St. 6. S. of Iceland 90 fm. 1 valve. 



- 81. S. W. of Iceland 485 - 1 



Further, it has been taken at Iceland at the following places : 



63°i5' N.L., 22°23' W. L 114— 170 fm. 11 valves. 



63°i8' — 2i°3o' — 94 - x valve. 



Vestmaunaeyjar 68—70 - 2 valves. 



63°i7 r / N. L., I7°39' W. L 87 - black sand with shells and stones. 1 valve. 



These localities all lie off the south coast. The largest shell measures 13.5 mm . One of the 

 shells from Vestmannaeyjar comes near to the variety leviuscula, the ribs being almost lacking. 

 At the Faeroes it has been taken at: 



6i° 9 ' N.L., 7 °54' W. L 180 fm. 2 valves. 



The largest of these valves is n mm . high. 



Distribution. This species reaches from Lofoten along the west coast of Europe into the 

 Mediterranean to the Aegean; according to Jeffreys it is also said to have been found at Newfound- 

 land and the northern Japan; the same author gives its vertical distribution as from 6 — 400 fm. 



Lima gwym has not earlier been recorded from Danish waters; in reality however it has been 

 taken in the Kattegat, namely, a specimen at Trindelen as also a specimen and a valve in the neigh- 

 bourhood of Fladen, 1372 — 29 fm., but an erronous determination placed it under L. subauriculata Mtg.3) 



Synonymy. With regard to the designation of the species the following information may be 

 quoted from Sykes^): "In 1863 Jeffreys described (Brit. Conch, vol.11, p. 81) a shell from the British 



I At the place cited Jeffreys also ascribes it a distribution to Patagonia and Japan, but in Zool. Chall. Exp., Part 

 XXXV, [885, p. 290, E.A.Smith refers the specimens in question to the nearly related species Lima goliath Sow.
