TEREBBATULA lata. 

 TAB. DIL—Jig. I. 



Spec. Char. Transversely oblong, convex^ regular- 

 ly plaited ; front elevated ; the perforated valve 

 flattest, with a produced beak ; plaits 40. 



r ORTY 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 ofMrs. 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. Dlh— Jig. 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.
