This species constitutes a link bctween Nod. legumen and Nod. calcar. Our lon^i^ 

 list of synonyms shows how steadily and ^radually this transformation goes on. It 

 does not attain any high development either on the coralline-gravel or on the chalk- 

 bottora, and remains a dwarf in comparison with the allied Nod. calcar from the same 

 localities. 



Figg. 36 — 37 coraes near to Crist. cymboides d'Ohb., Crist. nummulitica Gumb. and 

 others Avith a very slight helicoid arrangement of the first charabers. [t is not possible 

 to distinguish such pigmy forms from some forms of Nod. complanata. Defr. in their 

 earliest stage of growth.
