single dead specimen in 12-15 fathoms off the entrance to Strangford Lough. 
Aporrbais pes-pelecani, Linne. 
A well-known and common species, locally called “leg-of-mutton she . 
It lives in about 10 to 25 fathoms, hut is sometimes taken at both less and 
greater depths. 
[Cerithium metula, Lov&n. __ 
In dredged sand from the Turbot Bank— Hyndman, l8o9 Report. 
Erroneously recorded from the same vicinity in the 1857 Report ; Cerithiopsis 
pulchella was the species intended. It is a northern form, and its only 
British station is the Shetland fishing-hanks, where it fives in 45-96 fathoms 
(Jeffreys) ; the Turbot Bank specimens are manifestly fossil.] 
Cerithium retieulatum, Da Costa. 
Very common, living between tide -marks and to a few fathoms depth, 
everywhere. In a dead state it is common on the Turbot Bank. 
Cerithium perversum, Linne. 
“In shell sand, mouth of Belfast Bay, Mr. Hyndman ’’-Thompson (sub 
Triphoris adversus). Not uncommon in Turbot Bank sand— Hyndman ; 
very rare, in 12-15 fathoms, off the entrance to Strangford Lough— Dickie 
(sub C. adversum) ; in all instances dead. Specimens labelled “Bundoran” 
are in the Belfast Museum Collection. 
ORDER SIPHONOBRANCHIATA. 
Cerithiopsis tubereularis, Montagu. 
“Sandy beach at Magilfigan ; and in stomach of Scaup duck shot in 
Belfast Bay ’’—Thompson (sub Cerithium tuberculare). Hyndman several 
times dredged dead shells on the Turbot Bank. 
Ceritliiopsis pulchella, Jeffreys. 
Found by Mr. Waller in Turbot Bank sand— Hyndman. It is a rare 
species. 
[Ceritliiopsis costulata, Moller. 
Another of the Turbot Bank fossils ; it was dredged there by Waller and 
Hyndman (sub STcenea costulata and Cerithium niveum) and specimens from 
thence are in the Belfast Museum. It inhabits the northern seas, and Shet- 
land appears to be its most southern station.] 
Purpura lapillus, Linne. 
Very common, on rocks and stones, between tide-marks. Locally caned 
“ white wilk,” or “ dog wilk.” Dead shells occur on the Turbot Bank. 
Buccinum undatum, Linne. 
The eommon whelk, or ‘ 1 buckie, 
as it is locally called, is abundant
