TEREBRATULA acuminata. 
TAB. CCCXXI V.—Fig. 1. 
Spec. Char. Heartshaped, front much elevated, 
with a deep acute-angular sinus in the mar- 
gin ; surface finely striated. 
Syn. Conch. Anomites acuminates. Marlin 
Pet . Derb. tab. 32 and 33. f. 5, 0 , 7, and 8 . 
A rather gib hose shell ; the front is so much elevated, 
that the upper valve is nearly divided into two distinct 
ovate lobes : the beaks are very small, and the numerous 
striae inconspicuous. 
Found on Scaliber, near Settle in Yorkshire, in Der- 
byshire, and in the Black Rock near Cork, from which 
latter place S. Wright, Esq. has favoured me with spe- 
cimens. It strongly resembles the Terebratula, fig. 1, 
in plate 246, of the Encyclopedic Methodique, but is 
not so strongly striated. This is named T. spirifera. by 
Lamarck in his Hist. Nat. des Animaux sans Vert eb res, 
VI. p. 257. but I suspect he has confounded it with 
Spirifer cuspidatus.
