PECTEN, LIMA. 7 
* Pecten similis, Laskey. 
Pecten tumidus, 7uwrton; Pecten minimus, Sars. 
Habitat—In muddy sand and gravel, in 10 to 25 fathoms, 
off Ascog and Craigmore, Bute; Tan Spit, Cumbrae; Moll 
Dhu, Loch Fyne. A somewhat scarce species in a live state ; 
single valves are common. 
British distribution.—Local throughout all our seas, and 
at all depths from 2 to 95 fathoms. 
Foreign localities—Norway (Sars and others), northern 
and southern coasts of Spain and: Portugal (M‘Andrew), 
Mediterranean and Aigean (Forbes), Madeira, (M‘Andrew). 
* Pecten maximus, Linné. 
Ostrea maxima, Linné. 
Habitat—In 8 to 30 fathoms in nullipore, sandy gravel 
and dead shells, somewhat scarce but generally distributed. 
I have taken it at Port Bannatyne Bay and Craigmore in 
Bute; outside Tan Spit, in Cumbrae, and off Moll Dhu and 
Silvereraigs, Loch Fyne. Dr. Landsborough reports a giant 
§ inches long taken at Cumbrae ; my largest specimen mea- 
sures 64 inches in its greatest diameter. 
This scallop is rightly held in high esteem by gastronomes. 
Lister tells us that “Hi pisces ex testaceis post ostrea 
-maximé in deliciis sunt.” Both this and P. opercularis are, 
however, rather too sweet and luscious to suit our modern 
taste. 
British distribution —Throughout our seas, apparently 
more common in the south and west of England than in 
Scotland. Scotch specimens, however, seem to attain a 
greater size. 
Foreign localities.—Nearly everywhere from Norway 
(Lovén) to the Canaries (M‘Andvew), but appears to be 
absent from the Mediterranean, where Pecten Jacobzeus 
takes its place. 
Lima, Brugwere. 
Lima elliptica, Jeffreys. 
Habitat—A single young specimen and one large valve 
of this species have been taken by Mr. Robertson, off Kal- 
chattan Bay, Bute. I have not taken it myself, but have 
seen and verified the above named specimens,
