level j in some states of preservation, the worn surface 
is minutely punctated, but this is seldom observable. It 
is distinguished from the globose variety of T. digona 
t. 96. by the narrowness of its front. 
Collected in abundance at Nunney, near Frome, by 
the Rev. J. Ireland ; it has also been found at Bridport. 
TEREBRATULA emarginata. 
TAB. CCCC XXXV.— Jig. 6. 
Spec. Char. Subrhomboidal ; the lesser valve 
nearly flat, the other eonvex ; front defined 
by two angles or emarginate ; edge be- 
coming blunt by age. 
The inequality of the valves is a good character to 
distinguish this species by. When young the projections 
at the extremities of the short angular front, and which 
resemble those in T. digona, are hardly observable while 
in old individuals with almost flat borders, they are very 
conspicuous ; the perforated beak has a decurvent keel 
upon each side of it. 
A rather uncommon Terebratula, discovered at Nunney 
near Frome, along with several others, by the Rev. J. 
Ireland.
