[Considered by Davey & Verdier, 1974 and 

 Duxbury, 1980, to be &jr syn. of Hystrich- 

 osphaerina schindewolfii Alberti, 1961.] 



[Considered by Wiggins, 1975 and Dorhofer & 

 Davies, 1980 to be a.jt syn. of Pareodinia 

 Deflandre, 1947. We concur with Stover 

 & Evitt, 1978, who neither accept this 

 judgement nor the resultant transfer of 

 the type species.]
