66 THE MOLLUSCA OF THE FIRTH OF CLYDE. 
(M‘Andrew). In America it ranges from Greenland 
(Moller) to Massachusetts (Gould), as Cingula aculeus, fide 
Jeffreys. The Scandinavian, American,and Arctic localities 
are referable to the variety arctica; the type is more 
southern. ; 
Rissoa fulgida, Adams. 
Helix fulgidus, Adams ; Turbo fulgidus, Montagu ; Cingula 
fulgida, Hanley ; Rissoa pygmea, Michaud. 
Habitat—A few living and, more numerous, dead speci- 
mens were obtained in the Coralline zone on south and west 
sides of Cumbrae.. Mr. Norman records it as scarce in 
Lamlash Bay, Arran; and Kames Bay, Cumbrae. It is, 
however, a difficult species, and the specimens here referred 
to it may be regarded with a certain amount of suspicion. 
British distribution—Very common on the southern 
coasts of England and Ireland. The Clyde is the most 
northern locality which I have noticed. 
Foreign localities. — Western France and Spain, and 
throughout the Mediterranean Sea. M‘Andrew records it 
from the Canaries. 
* Rissoa soluta, Philippi. 
Habitat—tIn 8 to 20 fathoms sand and nullipore, on the 
Tan Spit and west side of Cumbrae; local, but not very 
uncommon. Mr. Norman and Dr. Landsborough have taken 
it in Lamlash Bay. 
British distribution—In deepish water on most of our 
southern, western, and northern coasts. The only east 
coast localities which I have noticed are St. Andrews 
(MIntosh), and Durham coast (brady and Robertson). 
Foreign localities.—Norway (Sars), French Atlantic 
coasts (De Folin and Jeffreys), Mediterranean, Adriatic, and 
AEgean Seas (Spratt and others). 
Rissoa cingillus, Montagu. 
Turbo cingillus, Montagu; Turbo vittatus, Donovan ; 
Cingula cingilla, Fleming ; Rissoa graphica and Pyramis 
cingillus, Brown. 
Habitat—Gregarious, and very abundant on the under 
side of stones at about half tide all round the south end of 
Cumbrae, and not uncommon generally throughout the 
district on stony beaches.
