Nodosarina communis D'ORB. var. obliqua LIN. 



Tab. I, figg. 1719. 



The line of distinction between Nod. obliqua and raphanus is just as faint and 

 untraceable as it is between Nod. communis and radicula. 



Slender varieties of Nod. raphanus are not distinguishable from N. obliqua but 

 by its bended axis. 



Figg. 17 19 come near to Dent, sulcata and acuta D'ORB., Dent, polyphragma, 

 Zippei (part.) REUSS, Nod. stiliformis SCHWAG. etc. . 



The strength, distance and number of the ridges, which like finished sculpture 

 adorn the shell, are subject to many degrees of variation. It has some propensity to 

 become quite smooth by age as if returning to Nod. communis. Sometimes again it 

 becomes very slightly striated. It is not scarce either on the coralline- or on the chalk- 

 bottom and attains a length of 22 mm. 



Fig. 19 represents a more finely ridged or rather finely wrinkled form with glo- 

 bular chambers. It resembles most Nod. Zippei (part.) REUSS. from the Bohemian 

 chalk. Those wrinkles become sometime very faint.
