NASSA LAMELLILABRA. 83 



Var. Woodii, nov. Plate V, fig. 19. 



Dimensions. — L. 7 mm. B. 3 mm. 



Dl^trihutioii. — Not known living. 



Fossil: Coralline Crag: Boyton. Waltonian ; Little Oakley. 



RemarJiS. — The shell here represented is from Oakley, and there is another from 

 Boyton in the York Museum belonging to the same group. It appears to agree 

 generally Avith N. vennsta except that the sculpture is coarser. 



Nassa Woodwardi, sp. nov. Plate V, figs. 20, 21 ; Plate XIII, fig. 18. 



Specific Cliaraciers. — Shell small, strong, distinctly conical ; whorls 6, flat, 

 rapidly and regularly diminishing in size, the last much the largest, ornamented by 

 about 12 straight nodular ribs, continuous except as interrupted by the suture, 

 crossed by inconspicuous spiral striae ; suture slight ; mouth ovate, with a labial notch 

 above, and a tooth on the left side as in the last species ; outer lip thickened outside 

 by a labial rib, denticulated within ; canal very short, turning to the left. 



Dimensions. — L. 8 ram. B. 5 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. Butleyan : Butley. 

 Probably elsewhere in the Red Crag. Wexford gravels, Rathaspic. Scaldisien : 

 Antwerp. 



Remarhs. — I believe this form to be distinct, although belonging to the same smal 

 and granulated group as the last ; it occurs not only in the English Crag but also 

 in the Scaldisien of Belgium and in the Wexford gravels. I dedicate it to the 

 memory of Samuel Woodward, a Norwich man, who in 1833 was publishing figures 

 of fossils from the Crag, and of his illustrious descendants who have made for 

 ever the Icenian patronymic Woodward a household name among geologists. 



It approaches N. redicostata, Bellardi, which occurs at St. Erth, but is not the 

 same.

Specific Characters. —Shell ovato-conical, elongate, ornamented by numerous 

 flexuous longitudinal ribs, about 20 on the body- whorl, and by faint spiral striations, 

 subgranulose where they intersect the ribs ; whorls flattened ; mouth large, ovate, 

 projecting beyond the canal, angulate above ; outer lip regularly curved, spreading.
