Distribution. — Recent : Eed Sea. Fossil, Pleistocene : raised 

 beach, 80 feet above sea-level, Wadi Qiieh, near Qosseir, K 1629 ; 

 Camp 6, Wadi Queh, K 1631. 



These are two excellent specimens. The septa of the primary 

 and secondary cycles are subequal, and the corallites are from 

 G-5 by 9 mm. or 6-5 by 10 mm, in diameter, and they are not 

 gyrose or so compressed as in G. irregularis, Ed. & H.

Klunzinger has founded this species, which he admits as a very 

 near ally of Prionasti-cea tesserifera, owing to the greater size of its 

 calices ; in P. tesserifera he records them as from 10 to 12 mm.
