PHILINE, APLYSIA. 103 
Philine aperta, Linné. 
Bulla aperta, Linné; Philine quadripartita, Ascanius ; 
Bullwa Planciana, Lamarck ; Lobaria quadriloba, Gmelin. 
Habitat—In sand, muddy sand, and gravel in from 8 to 
20 fathoms in Millport Bay and on the Tan Spit, Cumbrae 
(scarce); off Craigmore and Garroch Head (plentiful); at 
Lochgoilhead, about half a mile below Douglas Pier (not 
uncommon). Our Clyde specimens are generally small. Ina 
specimen dredged at Lochgoilhead there were two dark spots 
in “the place where the eyes ought to grow;” these spots 
presented the appearance of subcutaneous eyes, but whether 
they were so or not I cannot say, not having been able to 
preserve the specimen, of which, however, I have a drawing. 
This species occurs throughout our district, but is generally 
scarce. Mr. Robertson informs me that it is exceedingly 
abundant at Loch Ryan. 
British distribution—Ranging from St. Andrews on the 
east coast, and Oban on the west, to all our southern waters; 
it is locally common. 
Foreign localities—From Norway (Lovén, and others), 
throughout western Europe to Mogador and the Canary 
Islands, as well as throughout the Mediterranean, Adriatic, 
and Aigean Seas. The older authors—Linné, Chemnitz, &e.— 
give the Cape of Good Hope as the locus of this shell ; whilst 
Martini (who, however, probably confuses other species in 
his account) gives a nearly world-wide distribution, and 
quotes some fifty names, more or less barbarous, by which 
the shell was known in his day (1769). 
Famity Aptysup&, D’Orbigny. 
ApLysiA, Linné. 
Aplysia punctata, Cuvier. 
Aplysia hybrida, J. Sowerby, id. Forbes and Hanley. 
Habitat.—Occasionally in rock pools on the south end of 
Cumbrae, and more commonly in the Laminarian zone there. 
I have noted it also from Kamesburgh Bay, Bute. Mr. 
Robertson records it as common in our Firth. 
British distribution.—Throughout all our coasts; not 
uncommon, 
Foreign localities —All western and southern Europe from 
Norway to France, Spain, and throughout the Mediterranean 
Sea. M‘Andrew records it (as A. hybrida?) from Mogador 
and the Canaries,
