TAB, CCCXXXIV.— F/g*. 1 and 2.

 nutely striated longitudinally, and trans- 

 versely sulcated ; sulci distant ; no sinus in 

 the front,

 Derh. t. 36,/. 3. 



SftEit nearly twice as Wide as long;, wilh incurred beak» 



neither of which is perfdi'ated, but in the confined space 



occupied by the hinpje, there is an angular sinus. The 



longitudinal stria? are extremely minute and close, but 



the concentric furrows are conspicuous and rather remote. 



Until the internal structure of this and the following 



shell is disclosed by some happily preserved specimens, 



we must remain uncertain of the proper genus top place 



il'iinn under ; it is, however, clear that they are not true 



Tcrtbratulge : they are, very probably, Spirifers. 



From the ^Ictallifcrous Limestone of DerbjEhire.
