352 MARSHALL: ADDITIONS TO ‘BRITISH CONCHOLOGY.” 
Kellia suborbicularis Mont.—Jersey, in rock-pools at low 
water, attached by a byssus to Serfude (Duprey and 
J.T.M.); South Devon, in soft red sandstone at low 
water, nestling in the dead valves of Saxicava. 
Sowerby figures an apparently cleaned valve of Axinus 
Jerruginosus as Kellia abyssicola ; but the latter is a very 
different shell, like a young Venus dincta in shape, though 
thin and globular. It is the Ke/Mel/a abyssicola of Sars, 
and also what Jeffreys holds to be the fry of Lsocardia cor, 
as to which see my note under that species. 
Loripes lacteus L.—Jeffreys has noticed that the anterior 
side of the shell of this species is ‘sometimes indented or 
sinuous,” but does not notice the reason; and Forbes and 
Hanley, while describing the shell as ‘“‘devoid of all sculp- 
ture,” remark “that the upper front corner is peculiarly 
depressed, as an extremely indistinct, very shallow, and 
rather broad sulcus, emanating from the beaks, runs close 
to the dorsal edge and slightly indents the upper part of 
the front margin at its extremity.” But neither of these 
authors seem to have noticed, nor do their figures show, 
that there is also a central ridge. Each valve has two 
transverse irregular ridges—one commencing at the beaks 
and gradually broadening to the left of the front margin, 
and another from the beaks to the anterior side, where it 
forms a sinus in the circumference of the shell ; the former 
ridge is raised, while the latter is depressed. ‘The largest 
come from near Portland Island, and are {jths of an inch 
in diameter. 
L. divaricatus L.—Crow Sound, Scilly Isles, 8—1o f., valves 
only, abundant (Smart). These are more convex than the 
valves cast ashore at the Land’s End, and but half the size. 
Lucina spinifera Mont. — Sculpture, 40—50 concentric 
ridges. An adult specimen from Shetland has only 18. 
Jeffreys’ dimensions are too large; three-quarters of an 
J.C., viit., Jan. 1897.
