SCALARIA, ACLIS, ODOSTOMIA. 71 
Foreign localities—From Norway to Madeira, and 
throughout the Mediterranean, Adriatic, and Aigean Seas. 
Scalaria communis, Lamarck. 
Turbo clathrus, Linné (part) ; Strombiformis clathratus, Da 
Costa ; Cochlea variegata, Lister. 
Habitat—Mr. Norman obtained two or three specimens 
from the fishermen at Lamlash, said to have been dredged 
in the bay. Dr. Landsborough records it from the same 
locality, and Mr. Hennedy reports having procured it at 
Gourock. Of this species (which is often confounded with 
the preceding) I have never seen even a fragment in our 
Firth, and cannot help regarding its presence as rather 
doubtful. 
British Distribution—South and west of England, and 
all round Ireland. Leckenby records it from the Dogger 
Bank, and Laskey from Dunbar. 
Foreign localities—Norway (Lovén and others), Spain 
and Portugal (W‘Andrew), Mediterranean and Aigean 
(Philippi, Forbes, and others), Canary Islands (‘Andrew 
fide Jeffreys). 
FAMILY PYRAMIDELLIDE, Gray. 
Actus, Lovén. 
Aclis supranitida, Searles Wood. 
Alvania supranitida, S. Wood ; Turritella minor, Brown. 
Habitat—Outside the Tan Spit, in 18 fathoms, sand 
and nullipore. Only two dead specimens obtained. 
British distribution.—On our southern and western 
coasts from the Channel Islands to the Hebrides, but always 
scarce. 
Foreign localities—Norway (Lovén), Sweden (Malm and 
others), French Atlantic coast (De Jolin and _ others), 
Northern Spain, Madeira, and Canaries (M‘Andrew), Gulf 
of Lyons (Martin), and Algiers (Weinkauj). 
OpostomiA, Fleming. 
Odostomia nivosa, Montagu. 
Turbo nivosus, Montagu ; Pyramis nivosus, Brown ; Odos- 
tomia cylindrica, Alder ; id., Forbes and Hanley. 
Habitat—A single specimen of this shell is in Mr. 
Robertson’s cabinet, taken at Cumbrae. Mr. Norman has
