458 Mr. S. V. Wood's Catalogue of Shells from the Crag. 



coralline crag. I would further remark in support of the 

 above opinion, that there are in the coralline crag a few ge- 

 nera, which, if not possessing decidedly tropical characters, 

 have not hitherto been found in the North, viz. Pholadomyay 

 Chama and Lingula, Cancellaria, Cassidaria, Columbella ?, Te- 

 rebra, Pleurotoma, Pyrula and Mitra, 



I must again repeat, that the names for the new species are 

 merely provisional, and the synonyma introduced are those 

 only that I have considered requisite for the true understand- 

 ing of the species.

I have given this a name provisionally, and placed it in its present 

 position with considerable doubt. The volutions are numerous and 

 completely discoidal, partly enveloping the preceding whorl ; they 

 are not tubular, neither do they possess the regularity of a convoluted 

 mollusc. A similar shell has been figured by D'Orbigny as Opercu- 

 lina, but the removal of one side of several volutions shows the inte- 

 rior without partitions. Diameter jth of an inch. PI. V. f. 5.
