Genus LEIOSELLA Canu and Bassler, 1920 



Eschara quinconcialis Norman, 1867 is a recent species of the 

 genus Leiosella. The comparison of figures of Leiosella orbicularis 

 and of Leiosella rostrijera is very conclusive. Norman's species ought 

 to become the genotype; it has been discovered at Corse by Calvet, 

 1902, and it has been dredged in the Gulf of Oran (Canu Collection) 

 by P. Pallary; its detailed study will therefore be possible. 



Echaroides billardi Calvet, 1906, belongs also to this genus. It 

 is a Morrocan species still more southern than the preceding. 



Family ESCHARELLIDAE Levinsen, 1909 



The characteristics of this 

 family and the many genera 

 of the four subfamilies recog- 

 nized by us have been given in 

 our volumes of 1920 and 1923 

 and in our Gulf of Mexico 

 paper. We here add diagnoses 

 of genera which have been 

 overlooked in our previous 

 works. 



Subfamily 



SCHIZOPORELLAE 



Canu and Bassler, 1917 



Genus 

 SPHENELLA Duvergier, 1924 



The hyperstomial ovicell 

 is profoundly embedded in the 

 distal zooecium and can not be 

 closed by the operculum. The 

 apertura bears a long proximal 

 rimule. The frontal is a 

 granularplcurocyst surrounded 

 by areolar pores. There are aborted zooecia and also erect zooecia. 



Genotype. — Sphenella polymorpha Duvergier, 1924. 



Range. — Miocene (Helvetian) of France. 



Genus STROPHIELLA Jullien, 1903 



The ovicell is hyperstomial and never closed by the operculum. 

 The aperture bears a circular beaded anter and a rimule circular on 

 the ordinary zooecia and triangular on theoviceUed ones. The frontal

Strophiella tuberigcra Jullien, 1903. Zoo- 

 ecia, X25. The rimule is triangular on the 

 ovicelled zooecia (after Jullien, 1903), Gulf 

 of Gascogny.
