most compressed, but does not show any difference in its arrange- 

 ment of chambers from the first. Of the last species, two different 

 specimens are figured from the same side, and the figures show no 

 important difference from the other two species. 



Polymorphina communis var, etrusca Fornasini has an ovate test 

 with broadly rounded base, but the arrangement of its chambers and 

 the compressed test are the same as those of the present species, and 

 it can be safely put in the synonymy. 



Polymorphina obtusa d'Orbigny, figured by Fornasini, has almost 

 the same appearance as Fornasini's Polymorphina etrusca, and we have 

 no reason to separate them. On the other hand, d'Orbigny's species 

 figured by Terquem is from the figure a 4-chambered specimen, 

 having rather rounded chambers arl-anged in an alternating almost 

 uniserial series. It seems to be quite distinct from the specimen 

 figured by Fornasini. According to Terquem's description, his 

 Polymorphina obtusa has a compressed test. In this point it differs 

 from Pyrulina. It is impossible for us to place his species in any 

 known species.
