INFUNDIBULUM rectum. 
TAB. XCVII.—Fig. 3. 
Spec. Cuar. Conical, concentrically striated ; apex 
eentral, acute, turns of the spire obsolete ; 
valve rectangular ; columella slender. 
a 
Tue valve within this takes scarcely more than one turn; 
in the place at which it approaches the edge that forms the 
columella, it is expanded so as to have an angular form, and 
it has no part reflected, as in other species, like an um- 
bilicus. The striae of growth are very conspicuous. 
This has more the external character of Patella than most 
of the species of this Genus. It is from Holywells, near 
Ipswich, by favour of the scientific Mrs. Cobbold. 
INFUNDIBULUM obliquum. 
_ TAB. XCVII.—Fig. 1. 
Spec. Cuar. Flattish, smooth; apex curved, ad- 
pressed, oblique; internal plate two thirds the 
diameter -of the mouth. 
Sane ci oe 
Tus edge of the internal valve is reflected near the colu- 
mella, so as to resemble in some measure an umbilicus, as is 
the case also in several other species; the upper surface is 
regularly conical and very smooth, but the apex is bent 
towards one side. 
A perfect but small specimen from Brakenhurst, in Sus- 
sex, is represented ; the species is found much larger in the 
Cliff, at Barton, from which place the Rey. W. Bingley 
has kindly sent me specimens.
