Genus CALCITORNELLA Cushman and Waters, 1928a

Type Species. Calcitornella elongata Cushman and Waters, 1928a .

Description. Calcivertellid characterised by a nearly planispirally coiled initial stage followed by a serpentiform last stage.

Remarks. According to Henbest (1963), Apterinella Cushman and Waters, 1928b and Calcitornella are two synonyms among the Miliolata. However, Calcitornella is prioritary over Apterinella, because these genera have been described on p. 45-47 and p. 64, respectively, of the same publication. On the other hand, Apterinella was too poorly defined to be preferred to Calcitornella . That was first suggested by Browne and Pohl (1973), even if these latter authors have erroneously considered Calcitornella as a representative of the Fusulinata Pseudoammodiscidae .

Occurrence. Pennsylvanian-Permian; cosmopolitan.
