XOTES ON THE MAKIKE MOLLUSCA OF PORT- STEWART. 17 



the habitat of the type, while " the variety occurs in the 

 Channel Isles also, and on the coasts of Dorset, Devon, and 

 Cornwall." Alcock records it from Connemara. The type 

 is referred to in the " Medusa " records as occurring near 

 Minard, in Loch Fyne, in 15-20 fathoms; in the Dunoon 

 basin, in 20 fathoms; and off Carradaie, in 16-20 fathoms. 

 There are no Scottish records for the variety. 

 *P. septangularis {Mont.).— A single example of this rare species. 

 Smith records it from Ayr and Bute; Canon Norman states 

 it is rare in Lamlash Bay ; Dr. Robertson took a single 

 live specimen off Cumbrae. 

 P. iurricula (Mont.). — Abundant in the gravel beds near Rock 

 House. 

 Marginella Icevis (Don.). — Hyndman had recorded this from 

 MagiUigan. I was glad to secure one example from the 

 gravel bank near Rock House. It was not full-grown, and 

 had its apex slightly damaged. The shell is widely, though 

 very sparsely, distributed over the West Highlands, but 

 the only record from the Clyde is the dubious mention of 

 Ayr by the late James Smith. 

 Cyprcm europaa, Mont. — In great abundance on the sands, but 



more especially on the " Cowry Beach," near Rock House. 

 CylicJma cylindracea {renu.).—A single example washed up. 

 *Actceon tornatilis (L.). — " Port-Stewart — Miss Richardson. 

 Frequent on the Derry Coast, thrown up by the tide, from 

 the Bann to MagilHgan Point" (Praeger). Most of the 

 specimens obtained of this beautiful and distinguished- 

 looking shell were somewhat injured by the waves. 

 * Bulla hydatis, i.— This again seems to be a new record for the 

 North of Ireland. My specimen is a fragment, but quite 

 recognisable. Praeger does not mention the species, and 

 Jeffreys gives only Galway, Bantry Bay, Cork Harbour, 

 and Dublin Bay. The only Scottish record I possess is 

 "Deep water of Upper Loch Fyne," mentioned in the 

 • " Medusa " lists. It is possible that this may be right, but 

 more likely it is a mistake for Bulla utriculus.
