Nodosarinti legumen LIN. 



Tab. II, figg. 2031. 



Through such intermediate forms as Marginulina bullata Rss., etc., Nod. legumen 

 becomes closely connected with Nod. radicula. Its great affinity to Nod. communis has 

 been mentioned. 



The compression of its shell is often very slight. Sometimes it, is quite conspi- 

 cuous during a less adult stage but gives place to a cylindrical form by age. The incli- 

 nation of the septa to the shells axis is also very variable. But it will still be neces- 

 sary to retain this Linnean species, as it must be used as are preservative type of those 

 broader forms, on which D'OiimGNY and others have founded their genera Marginulina 

 and Vaginulina. 



Frondicularia lingua BOLL, is a connecting link between Nod. legumen and Nod. 

 complanata DEFR. 



When in the young state the shell is more or less coiled up to a spiral, inter- 

 mediate forms to Nod. crepidula FIGHT, and MOLL are originated. 



The pigmy forms of Nod. legumen (0,50 1 mm. in length) are not uncommon 

 in the chalk-ooze; the stouter forms (about 12 mm.) occur in the coralline-gravel. 



Figg. 20 21 b is Vac/in. Icevigata ROM. or Vagin. badencnsis n'Oim.; it is a dwarfish 

 form from the chalk-bottom. 



Figg. 22 25: highly developed forms; some with the older chambers compressed 

 and those of later growth cylindrical; some with quite cylindrical chambers through 

 all stages of growth. The shell is thin, nearly transparent and of a silky lustre. 



Figg. 26 26 b: peculiar form, approaching Nod. crepidula. 



Figg. 27 27 b: the same as Margin, ensis REUSS and Margin, lituus n'OuB. etc. 

 pygmies from the chalk-ooze. 



Figg. 28 31: stouter forms from the coralline-gravel.
