THE 
MARINE MOLLUSCA OF NORTHUMBERLAND. 
(In continuation of the list contributed by G. P. Bulman.) 
B y marie y. lebour. 
We are glad to be able this year to make some interesting 
additions to our local molluscan fauna ; in fact, in one or two cases, 
to record shells which are not even in Alder’s classical list, and others 
which are decidedly rare. Several of the shells mentioned below, 
recorded in a previous list, were then only represented by dead or 
immature specimens, but have now been found living and abundant 
on our coasts. 
PELECYPODA. 
Family — Anomiidjs. 
Genus — Anomia. 
A. ephippium, (L.) and v. aculeata (Midler). 
Small specimens very common on the under side of stones at low 
water, Cullercoats. Worn specimens dredged at a depth of about 
17 fathoms, also one live specimen of the variety dredged at a depth 
of about 39 fathoms. 
Family — Mytilida?. 
Genus — Mytilus. 
M. bar bat us (L.) 
One young specimen taken four miles off Cullercoats in 40 
fathoms. (On the authority of Mr. G. P. Bulman.)
