Var. inornata is also closely allied to B. elongata, for the latter often has the 

 exposed portion of the penultimate chamber pear-shaped; and there are few of 

 those bearing that character that would not be assigned to elongata. 



To complete the series of typical Biloculinx referred to at page 93, we here 

 add a brief synonymy of B. bidloides, d'Orb.
