CHEMNITZIA. 255 



The animal is white, slightly tinged with brown. The 

 tentacula are rather long, lanceolate, set well apart, and 

 bearing the eyes nearly centrally at their bases. The 

 mentum is rather narrow and bilobed : the foot is oblong- 

 lanceolate, obtusely angled in front, triangular behind. 



This species aj^pears to be the Turritella indistincta of 

 Dr. Fleming, who found his shell at Loch Broom. It is 

 a rare animal, occurring occasionally and sparingly in the 

 Lochs of the Frith of Clyde, and in the Hebrides. We 

 have taken it alive in twenty fathoms water off Mull, 

 where it has been taken, as well as in Loch Fyne, by 

 Mr. M'Andrew. Mr. Jeffreys has found it at Oban, and 

 in the Rosshire Lochs and Mr. Barlee in several localities 

 on the west coast of Scotland. It inhabits the coralline 

 zone. 



Loven has taken it on the west coast of Sweden.

The identity of this shell with the T. indistinctus of 

 Montagu is rather traditional than positive, since the Ian-
