LUCINA. 57 



Occasionally on the fish-lines, twenty-five miles east of Fern 

 Islands, in thirty fathoms (King, Ann. Nat. H. vol. xviii.). 

 In Scotland it is plentiful in the Clyde (Smith and E. F.), 

 especially around Arran, and many localities of the inner 

 and outer Hebrides (Jeffreys) ; Skye, in forty fathoms, 

 mud ; Zetland, alive, in four, seven, fifteen, seventy and 

 eighty fathoms (M 'Andrew and E. F.); and at Deal Voe, 

 in twenty fathoms (Jeffreys); Aberdeenshire (Macgil- 

 livray). "It occurs on each side of the Irish Coast; 

 dredged in Strangford Lough on sand and mud, from* ten 

 to twenty fathoms, by Mr. Hyndman and myself" (W. 

 Thompson). In various localities on the West Coast of 

 Ireland, as at Clew and Killery, in from three to ten 

 fathoms (Thompson, R. Ball, and E. F.); Dublin Bay 

 (Alder); Bantry (Humphreys); Youghal (R. Ball); Cape 

 Clear, in thirty fathoms (M'Andrew). 



Abroad, it ranges northwards to Finmark, and south- 

 wards to the Mediterranean. As a fossil it is found in 

 some of the Scottish glacial beds (Smith), and in the crag 

 (S. V. Wood).

* This not being the Lucina which Linnaeus intended to indicate under the 

 appellation of Tellina lactea, we have reluctantly changed the name to that which 

 Turton bestowed upon a shell so precisely identical (we have compared his own 

 specimens) that we cannot even term it a variety.
