The specimens collected are rather small, and more globu- 

 lar than recent examples, the chambers not being flattened as 

 usual. The supplemental sutural apertures are generally to be 

 seen in the Biarritz specimens. The species is not rare and 

 seems to be most frequent in the middle and lower portions 

 of the Marl, and has not been found at ail in the higher Gather- 

 ings.
