TEREBRATULA lata. 
TAB. DIL —Jig. 1. 
Spec. Char. Transversely oblong 1 , convex, regular- 
ly plaited ; front elevated ; the perforated valve 
flattest, with a produced beak ; plaits 40. 
Forty regular neat plaits, ten or twelve of which are 
raised with the front, cover the surface of this pretty 
Terebratula ; it would be twice as wide as long were 
not the beak produced beyond that proportion. 
Found in the green Sand. We have specimens, through 
the kindness of Mrs. Gent, from the Devizes Canal ; ofC. 
W. Loscombe, Esq., from near Sidmouth ; and of H. H. 
Goodhall. Esq., from Farringdon in Berkshire : the one 
from the last place is coloured with ochre, and empty ; 
the others are nearly white, and filled with stone. 
TEREBRATULA depressa. 
TAB. DII.— ^g. 2 
Spec. Char. Triangular, depressed, regularly plait- 
ed ; front elevated ; lateral angles rounded ; 
beaks produced ; plaits 20. 
When so young that the front is hardly elevated, this 
shell is almost orbicular ; in which circumstance it differs 
from the last, the proportions of which do not vary much 
by age : the plaits are sharp, about eight of them are 
raised with the front. 
Found at Farringdon by H. H. Goodhall, Esq.
