Mediterranean Mollusca. 29 
{tLimopsis pygmea, Ph. 
Pectunculus pygmeus, Moll. Sic. i. p. 63, t. v. f. 5. 
From 217 fms. A single but fresh valve. A Pliocene 
fossil of Italy and the English Crags; hitherto unknown as 
recent or living. The specimen mentioned in the supplement 
to ‘ British Conchology’ (vol. v. p. 175) as from Corsica is 
L. minuta. 
Malletia obtusa, M. Sars. 
From 337-464 fms. 
Malletia cuneata, Jefireys. 
From 337 to 1536 fms. 
Axinus planatus*, Jeftr. 
SHELL triangular, expanded, and somewhat flattened, thin, 
lustreless, and opaque: sculpture, an angular ridge running 
down the middle, with a shallow furrow on the anterior side, 
besides regular slight concentric riblets in the line of growth, 
and numerous intermediate minute striz: colour whitish : 
epidermis filmy and scarcely perceptible : margins rounded in 
front, sinuous (as in A. flewuosus) on the anterior side, ob- 
liquely and abruptly truncated on the other side, deeply exca- 
vated or concave below the beak: beaks prominent, pointed, 
and incurved: dunule semicordate, with a thickened edge: 
ligament enclosed in a short, narrow, and curved groove: 
hinge-line triangular, occupying only a small portion of the 
entire circumference: hinge-plate thick: teeth none: inside 
glossy, exhibiting the obverse of the riblets but no longitu- 
dinal strie: muscular scars indistinct, lL. 0°55, B. 0°5. 
From 432-544 fms. ; a single valve only and the fragments 
of another. 
With this species was dredged an unusually large and 
rather flattened valve of what I should consider A. fleruosus, 
var. polygona, which shows the same longitudinal strie on 
the inside that, according to the Abbé Brugnone, distinguish 
Ptychina biplicata of Philippi from A. flexuosus. 
A. transversus (Lucina transversa), Bronn, has a different 
shape, texture, and sculpture. 
tAainus orbiculatus, Seg. 
From 214 fms. 
}Pecchiolia granulata, Seg. 
From 127 to 301 fms. ; of large size. 
* Flattened.
