VELUTINID. 
Lamellaria perspicua (Linn.). 
North Berwick in shell sand, small and 
not abundant (J/.). 
Velutina levigata (Penn.). 
Firth of Forth (Zd. Mus.) ; on the beach 
at Dunbar, North Berwick, Longniddry, 
Granton, and Cramond (J/.). 
This species is not uncommon in a few 
fathoms of water. We have dredged it 
in Kirkealdy Bay, 9 fathoms; off Inch- 
keith, 5 fathoms; and in Aberlady Bay, 
9 fathoms. We have also collected it 
dead on the beach at Largo Bay. 
APORRHAIDA:. 
Aporrhais pes-pelecant (Linn.). 
Firth of Forth (J/8.); off Inchkeith 
(Com. Mar. Zool.); Firth of Forth, 30 
fathoms (Metz. and Mey.). 
Brought in alive by the Newhaven fisher- 
men. On the beach at North Berwick 
and Craigroyston (J/.). 
Not uncommon. We have dredged it in 
Largo Bay and off Kirkcaldy, and have 
also obtained it on the beach at Largo. 
CERITHIIDA, 
Cerithium reticulatum (Da Costa). 
A worn fragment on the beach at North 
Berwick. I donot think the species lives 
on this coast. | However I found a perfect 
though dead shell on the Northumbrian 
shore at Alnmouth (JZ). 
III. StPHONOBRANCHIATA— 
BUCCINID&. 
Purpura lapillus (Linn.).
