Characters.—Shell elongated, arcuate, tapering; composed of numerous (six to 
fifteen) chambers, which are subcylindrical and more or less ventricose, with the septal 
lines generally constricted, and the surface covered with riblets, varying in number and 
size in different specimens. Length {th to aths inch. 
Dentalina obliqua may be regarded as the curved form of Wodosaria raphanistrum. 
Like the latter, it has usually a large number of chambers, and it is covered with similar 
parallel longitudinal ribs, and under favorable circumstances it attains to similarly large 
dimensions, the only difference being a more or less curved mode of growth. Some 
specimens seem rather to be the curved forms of WV. raphanus; but there is little 
or no real difference. ‘The straight tapering variety of NV. raphanistrum is NV. acicula, 
Lamarck. 
Mr. Searles Wood’s specimens from Sutton are fine and numerous; but we have not 
obtained it from other Crag beds. It is not an uncommon form in the various Secondary
