This large and distinct species has never been described, 

 and no figure of it exists in the litterature. 



The valve is gently arcuate, with slightly protracted, roun- 

 ded ends. It has a very distinct raphe, following at some distance 

 the lower margin and ending in very distinct, downwards curved 

 end-nodules. The whole valve is covered with rows of puncta, 

 which (as is seen on the F. W.) project in short bristles. The 

 puncta are 13 in O.oi m. m. and the rows of puncta 13 on the 

 middle, 15 at the ends in 0,oi m. m. — In T. W. the outline is 

 lanceolate, with rostrate ends. Length of the valve O.u to 0,18 

 m. m., breadth of the valve 0,0 2 5 in. m.
