TEREBRATULA coneinna. 
Spec. Cuar. Nearly globose, acutely plaited, mid- 
dle elevated by seven plaits; twelve or more 
plaits on each side; beak projecting. 
A very elegant shell, the plaits are very uniform and neat, 
and continue sharp to the very beak: it is rather wider than 
long; the length and depth are about equal. 
The peculiar neatness of this shell has given it a name. 
It is from Aynhoe. 
TEREBRATULA obsoleta. 
TAB. LXXXIUI.—Fig. 7. 
Spec. Cuar. Nearly round, gibbous, plaited ; middle 
of the front a little elevated by seven plaits; 
sides having from seyen to eleven plaits: beak 
projecting. |

A rrarrer and less neat shell than the last, and the middle 
of the front is less elevated. Depth about two-thirds the 
length. . 
This species was sent from Felmersham near Bedford, by 
the Rev. T. O. Marsh, in 1813, it does not appear to be 
common. I believe the same species is found in Wiltshire, 
but the specimens are larger, and the seven ridges are not 
always so perfectly distinguished from the seven lateral 
plaits. I have received it also from Gunton near Yarmouth, 
by favor of Mr. Downs.
