MYA V. scripta. 
TAB. CCXXIV.---Figs. 2, 3) 4, and 5. 
Spec. Cuar. Transversely oval, subequilateral, 
convex, smooth, thin, with obtuse angularly 
bent ridges upon the central part; angles of 
the ridges acute, in an oblique direction. 
(Var. 8) with an oblique elevation bounding the 
anterior side. 
Figs. 2 and 4. 
"Tus differs from the species last described only in the 
oblique direction in which the angles of the ridges suc- 
ceed each other, and these angles being more acute, 
altogether giving a different contour to the surface. In 
var. 8 the elevation which distinguishes it may possibly 
be the effect of pressure. 
I have this species from the Kelloways rock at Little 
Somerford, by favour of the Rev. H. Steinhatier, whose 
specimen is shewn at fig.3; and from Kelloways, through 
the kindness of Mrs. Wetherall, who resides near the 
spot. Fig. 5 is from Bedford Castle, picked up by 
Mr. Goodhall. 
The variety, figs. 2 and 5, are from two individuals 
in the possession of the Rev. W. D. Conybeare, who 
got them at Claydon, in Oxfordshire, out of the Shuc- 
borough bed of yas: they are very far from perfect. 
MYA angulifera. 
TAB. CCXXIV.---Figs. 6 and 7. 
Spec. Cuar. Transversely elliptical, elongated, 
eibbose, with obtuse angularly bent ridges 
upon the surface ; anterior half widest, gaping ; 
angles of the ridges acute, in an oblique di- 
rection. 
"Tur ridges extend beyond the central part of this shell, 
and consequently many of them reach the front without 
being bent. The width is almost three times the length; 
the posterior side is very small. — 
Found in Limestone, in what is called by Smith the 
Fullers’ Earth bed, at Smallcomb and Beacon Hill, Bath, 
by the Rev, H. Steinhater.
