118 Part III —Fifteenth Annual Report 
Mangelia attenuata (Montagu).—In the vicinity of Minard, in 15 to 
20 fathoms (M.). 
Mangelia levigata (Philippi).—In the same locality as the last (M.). 
Bela turricolla (Montagu).—East Loch Tarbert (living); off Battle 
Island, dead (B. & S.); Upper Loch Fyne, in the vicinity of Minard, on 
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 antigua (Linné).—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.). 
Buceinum undatum, Linné.—East Loch Tarbert (B. & §.). 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.). 
Nassay incrassata (Strom).—East Loch Tarbert (B. & 8.). Minard, in 
12 to 20 fathoms, and between tide-marks (M.). 
Nassa reticulata (Linné).—East Loch Tarbert (B. & S.). Minard, in 
12 to 20 fathoms, and between tide-marks (M.). 
Nassa pygmeea (Lamarck).—In the vicinity of Minard, in 11 to 20 
fathoms (M.). 
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 (Linné).—Commonly distributed, especially in 
shallow water. Vicinity of Minard, in 12 to 20 fathoms (M.). 
Trivia europcea (Montagu).—On rocks at extreme low water in Loch
