LAMELLIBRANCHIATA. 



43 



At West Iceland, at the two stations in Brede Bugt (86 and 87) mentioned above, 

 and at South Iceland: 



Vestmannaeyjar 49 fin., clay with a little mud. 4 valves. 



63°2i' N. L., I7°3i' W. L 69 - , sand. 1 valve. 



At East Iceland the species reaches the considerable size of io' 1 "".; of the shells from the rest 

 of Iceland none are over 5.5 m '". 



Faeroes. 

 Here L. subauriculata has been taken at the following places: 



Bordovig 7 — 10 fm., black sand, small stones, 



Laminaria. 2 valves. 



— 10 - , sand, Laminaria. 1 valve. 



Ejde 5 — 6 - , coarse black sand. 9 valves. 



Fundingsfjord 12 — ca. 20 - , coarse sand and clay. 4 



Vestmanhavn 3' .. — 5 - , fine black sand. 1 spec, and 10 valves. 



5- 6 - , 3-35 



— 10 — 30 - 3 valves. 



Sorvaag 14— i6y 2 - 1 valve. 



13 miles S. of Myggensesholm ca. 70 - 4 valves. 



9 — E. S. E. of Bispen - 70 - 40 



16 — E. by S. of south point of 



Nolso 80 - 4 



13 — W. by S. of Munken ca. 150 - ca. 100 valves. 



The maximum size of the shells taken inshore is 5 """., of those taken further out to sea 6 mm . 



Distribution. On the European side L. subauriculata ranges from West Fiiimarken 1 ) to the 

 Canary Isles, also in the Mediterranean to its eastern part; doubtfully living in the Kattegat at present. 2 ) 

 On the American side it reaches from the Strait of Florida to Labrador and the southern West 

 Greenland; it is also said to occur on the west coast of North America, according to Jeffreys. 



At Norway, the Fseroes, Iceland and Greenland its vertical distribution is from 10 — 150 fm. On 

 the other hand, Jeffreys gives its vertical distribution to extend from 10— 1785 fm. M and Locard 

 also records it from great depths, down to 2200111. ■»); but as the species of the genus Lima are very 

 difficult to distinguish from one another, it is conceivable that erroneous determinations have given 

 rise to the records of these enormous depths (cf. under L.similis 11. sp.). 



9 According to G. O. Sars it has not been found at East Finmarken, but it is recorded from the Munnan Coasl 

 (II erzenstein: Beitrage zur Kenntnis der Fauna der Murmankuste und des Weissen Meeres. I. Mollusca, 18S5, p 

 is stated by W. Leche to occur at Nova Zembla and ill the Kara Sea, but this conies from an erroneous determination, the 

 specimens in question belonging to Lima hyperborea ni. (cf. the latter). 



2) Only a single shell namely has been found at "Fladen" (Eastern Kattegat); as the other specimens taken in the 

 Kattegat (including one living), which were referred by C.G.Joh. Petersen to L. (Det vidensk Udb. af "Hauch"s 

 Togter, 1S89, p. 66), do not belong to this species, but to L.gwyni Sykes (= L.elliptka Jeffreys, non Whiteaves
