One small but fairly typical specimen of this abnormal species. 

 The reason for its inclusion in the genus Pulvinulina is, we must 

 confess, far from obvious. d'Orbigny, who founded the species, 

 referred it to the genus Planorhulina, and its affinities certainly 

 seem to lie in this direction. Brady, however, considered that its 

 relationship to Pulvinulina could be established by " intermediate 

 gradational forms." Although the species occurs with some fre- 

 quency in Mediterranean gatherings, we have not ourselves seen 

 sufficient evidence of these intermediate forms to establish its 

 position with any certain ty.

Fossil, pyritised. According to Brady, the range of this species 

 does not extend beyond the Tertiary period. The specimens are all 

 referable to Fitchel and Moll's var. /3, which differs from var. a, or 

 true auricula, in the sharp peripheral edge and limbate sutures. 

 The two forms, however, run together to such an extent that they 

 are hardly worth separation.
