90. Bolivina decorata Jones. 



Bolivina decorata (Jones MS.) Wright, J. in Cretaceous Foraminifera of 

 Keady Hill, Co. Derry, Proc. Belfast Naturalists' Field Club, 

 Appendix 1885-6, p. 330, pi. xxvii. figs. 7, 8. 



Fossil. A few specimens only, evidently cretaceous. This 

 rather striking species is apparently nearly allied to Bolivina 

 reticulata Hantken. The description, as given by Wright, is as 

 follows : " Test elongate, compressed, broad at the oral end and 

 tapering to a rounded point at the aboral extremity ; surface 

 ornamented with prominent oblong tubercles, which are arranged 

 in oblique rows." 



The species is common in the Chalk obtained by Wright from 

 hollow flints at Keady Hill, Co. Derry, and probably elsewhere 

 in similar material.
