MANGELIA. 485 



Clark describes it as white, with opaque intense snow- 

 white flakes. The siphon is speckled with pink. The 

 tentacula are short, thick and strong as far as the eyes, 

 short and finely attenuated beyond them. Of all the 

 species he had seen, this had the eyes nearest the points. 

 The foot is truncate and but slightly auriculated in front ; 

 lanceolate behind. There is no trace of an operculum. 



This is a rare British shell. Dead in ten fathoms at 

 Guernsey, Weymouth and Torbay, but scarce (S. H.) ; 

 rare at Exmouth, inhabiting the coralline zone (Clark) ; 

 in twenty fathoms. Frith of Clyde (J. Smith and E. F.) ; 

 twelve to fifteen fathoms, Bantry Bay, Ireland (M'An- 

 drew) ; Arran Isles, Galway (Barlee). It is a Mediter- 

 ranean species.
