344. MARSHALL: ADDITIONS TO “BRITISH CONCHOLOGY.” 
Fossil in the Belfast deposit (Grainger) ; erroneously re- 
corded as L. pernula. 
Var. brevirostris Jeff_—Generally distributed throughout 
the Hebrides and as far north as East Sutherlandshire. 
The specific name is so absurdly inappropriate that it 
might well be altered. 
L. lucida Lov. was taken in the ‘Lightning’ cruise between the 
Hebrides and Feerces, also in the Feerce Channel with var. 
dechivis (‘Triton’), but has not been dredged on the 
British coasts. 
A fine perfect specimen and two valves of L. arctica 
Gray, apparently sub-fossil, were dredged in Loch Torri- 
don during the ‘Porcupine’ cruise of 1869, and with them 
were perfect, but dead, perhaps also sub-fossil, specimens 
of ZL. lenticula Moll. I have a valve of the latter species 
from Eigg Island, 20 f., which is also probably sub-fossil. 
Limopsis aurita Broc.—West of Ireland, 345 f., and Atlantic 
off Scilly, 690 f., with Z. dorealis (‘ Porcupine’) ; Feerce 
Channel 516 f. (‘ Triton ’). 
Pectunculus glycymeris L.—Low water (Channel Islands) 
to go fathoms. It is eaten in Jersey, and may often be 
seen in the shell-fish market there. Specimens from the 
Channel Islands differ from those of the British coast in 
being orbicular. The largest come from Falmouth, and 
exceed 3 in. in diameter. 
The fry and young resemble Zzmopsis; they are zof 
square, but the upper margin is squarish, owing to the 
hinge-margin being straight and having projecting ears ; 
and the very young are certainly crenulated. 
Var. pilosa Jeff.—‘‘ Not Azca pilosa Linné, which is thicker, 
larger and more globose ; the longitudinal striz are more 
distinct, the hinge area wider, and the teeth larger and 
fewer. The synonyms of each have been intermixed.”
