and live specimens are semitransparent : sculpture consisting 

 of extremely fine and obscure microscopical spiral lines only ; 

 there is no peripheral keel at any stage of growth: colour less 

 white in live specimens : spire proportionally shorter, and 

 never twisted : whorls 15-16, more compact and less flattened 

 than in the other species : suture marked by a broad clear 

 band : mouth narrower : outer lip rather more deeply sinuated 

 above : inner lip slighter and thinner. L. 0-45. B. O125. 



Yar. ruhro-tincta. Half the usual size and sometimes a 

 little curved ; upper part exhibiting the pink ramifications of 

 the liver. 



HABITAT : With the last species, from 20 to 73 f., in 

 Shetland (J. Gr. J.) ; west of Scotland (Barlee, Nor- 

 man, and J. Gr. J.) ; Coquet and Berwick Bay (Mennell); 

 Arran Isles, co. Galway (Barlee) ; Cork (Humphreys) ; 

 Exmouth (Clark) ; Plymouth (Barlee) ; Falmouth (Miss 

 Vigurs, fide Cocks) ; Guernsey (Barlee and J. Gr. J.) . 

 The variety occurs in Loch Fyne, Shetland, and the 

 Channel Isles. Red Crag at Walton-on-the-Naze 

 (Wood) ; Palermo (Philippi) ; tertiaries of Sienna and 

 Pelora (Cantraine) ; upper Miocene at Biot near Antibes 

 (Mace) . Distributed in a living state along the coasts 

 of the North Atlantic, from Finmark (Sars) to the 

 Canary Isles (M 'Andrew), and throughout the Medi- 

 terranean (Cantraine, Philippi, and others) and Adriatic 

 (Brusina) to the ^Egean (Forbes) ; the recorded depths 

 range from 1 5 to 60 f. 



The animal floats ; and it remains suspended in that 

 posture, by means of a byssal thread, the operculum 

 then closing the mouth of the shell. It differs from 

 that of E. polita in the tentacles being white instead of 

 tipped with orange ; nor has the head- flap any coloured 

 V-shaped mark. The upper whorls of the shell are 

 empty in this and every other species of Eulima that I 

 have observed in a living state. 



I am inclined to refer to this species the E. subulata
