234 PYRAMIDELLIDiE. 



The animal which we have examined alive at Round- 

 stone Bay, on the west coast of Ireland, has rather longer 

 subulate tentacula than its British congeners have ; the tips 

 of these organs are white, and the bases and about a third 

 of their lower parts of a brilliant vermilion colour ; the eyes 

 are large and placed within white spaces at the bases of 

 the tentacula. The sides of the neck are clouded with 

 vermilion. The foot, as usual long and produced in front, 

 and rest of the animal are white. The lateral flaps are 

 not greatly developed. The mentum is not marked by 

 any coloured line. Philippics figure and description of 

 the animal in Mediterranean specimens accords with our 

 observations. An example taken on the Northumberland 

 coast, and described by Mr. Alder, had a yellow body, 

 beautifully variegated with carmine, which formed an ir- 

 regular band on each side. The tentacles and foot were 

 white. Mr. Alder observes that the liver, as seen through 

 the shell, is green in disiorta, and purplish in j)oUta. 



This species is probably sometimes confounded with the 

 young of other forms. It has a wide range in Britain, 

 Guernsey, and Sark (Barlee); Exmouth (Clark) ; White- 

 sand Bay (Jeffreys) ; off the Isle of Man in thirty fathoms 

 (E. F.) ; Loch Fyne (Jeffreys) ; in eighty-two and ninety 

 fathoms, Zetland, and in twelve fathoms, Orkney, always 

 in sand (M'Andrew and E. F.) At Whitburn, on the 

 Northumberland Coast, taken by the Rev. Cr. C. Abbes 

 (Alder). " On the east, west, and south coasts of Ire- 

 land" (W. Thompson) ; Arran in Gal way (Barlee) ; Ban- 

 try Bay and Cork harbour (Jeffreys). 



It ranges from Norway to the Mediterranean.
