Nodosarina radicula LIN. var. ncalaris BATSCH. 



Tab. I, fig 8. 



Is the pigmy-form of the preceeding and too closely related to that, to attain 

 the rank of species. Such forms as Nod, injlata Ess., Nod. nana REUSS, Nod. bade- 

 nensis D'OiiB., Nod. tenuicostata COSTA, etc. have the character of both. 



Its characteristic distinguishing feature should be the thinness of [the shell and the 

 prolongation and slenderness of the chamber-necks. But such marks are no longer 

 recognised as being of any distinctive importance in this class, where each species 

 seems to have its dwarfish, tiny forms, which during their whole life remain in a sort 

 of juvenile stage. 



It has been stated above, that the shape of the necks cannot be of any specific 

 importance. 



This form occurs both on the chalkbottom and in the coralline-gravel. It attains 

 seldom more than 1 1,5 mm. in length.
