Mangelia laevigata (Philippi). — In the same locality as the last (M.). 



Bela turricolla (Montagu). — East Loch Tarbert (living) ; off Battle 

 Island, dead (B. & S.) ; Upper Locli Fyne, in the vicinity of Minard, ou 

 both east and west sides and in the centre, in 11 to 70 fathoms (M.). 



Bela Trevellyana (Turton). — Upper Loch Fyne, in 11 to 20 fathoms (M.). 



Neptunea antiqua (Linne). — Taken in the vicinity of Minard ; on the 

 east and west sides and centre, and near the head of the loch, in 10 to 70 

 fathoms, and between tide-marks (M.). East Loch Tarbert, living (Mihi). 



Sipho gracilis (Da Costa). — Loch Fyne (B. & S.). Vicinity of 

 Minard ; on the east and west sides and centre ; and near the head of the 

 loch in 10 to 70 fathoms (M.). 



Buccinum undatum, Linne. — East Loch Tarbert (B. & S.). At 

 various places from the vicinity of Minard to near the head of the loch, 

 and from between tide-marks down to 70 fathoms (M.). In deep water, 

 Upper Loch Fyne (G.). 



Nassa incrassata (Strom). — East Loch Tarbert (B. & S.). Minard, in 

 12 to 20 fathoms, and between tide-marks (M.). 



Nassa reticulata (Linne). — East Loch Tarbert (B. <fe S.). Minard, in 

 12 to 20 fathoms, and between tide-marks (M.). 



Nassa pygmcea (Lamarck). — In the vicinity of Minard, in 11 to 20

Trophon truncatus (Strom). — Tarbert Bank, Loch Fyne ; not very 

 rare in suitable localities. 



Trophon muricatus (Montagu). — In Upper Loch Fyne, in 12 to 25 

 fathoms (M.). Tarbert Bank, Loch Fyne (Mihi). Alfred Brown does 

 not include this species in his work on the Mollusca of the Clyde, prob- 

 ably because Trophon clathratus may sometimes have been mistaken for 

 it. I have both species in my collection, and when they are placed side 

 by side the difference between them is quite apparent. There can be no 

 doubt that the specimen from Tarbert Bank is Trophon muricatus. 



Purpura lapillus (Linne). — Commonly distributed, especially in 

 shallow water. Vicinity of Minard, in 12 to 20 fathoms (M.). 



Trivia europwa (Montagu). — On rocks at extreme low water in Loch
