TEEEBKATULA acuminata. 



TAB. CCCXXIV.— Fi^. 1. 



Spec. Char. Heartsbapecl, front much elevated, 

 with a deep aciite-angidar sinus in the mar- 

 gin ; surface finely striated. 



8yn. Conch. Anomites acuminatns, Marlin 

 Pet. Bcrh. tab. 32 and 33. /. 5, G, 7, and 8. 



A KATiiER glbbose shell ; the front is so much elevated, 

 that the upper valve is nearly divided into two distinct 

 ovate lobes : the beaks arc 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 Aniuiaux sans Vertebres, 

 VI. p. 257. l)ut I suspect he has confounded it with 

 Spirifer cuspid atus.
