Affinities. — We possess only a small fragment consisting of two zooecia; we are 

 not certain therefore of our determination, as this has been made almost entirely on 

 the micrometric measurements. The opesium is oval, the point above: the cryp- 

 tocyst is granulated ; the mural rim has a width of O.OS mm. and is granulated 

 transversally. 



Occurrence. — Lower Miocene (Bowden horizon) : Rio Gurabo, Santo Domingo 

 (rare) . 



Habitat. — Andaman or Xicobar Islands ? (Levinsen) ; Tortugas Islands, Florida 

 (Osburn) . 



Plesiotype.—Cat. No. 68482, U.S.N. M.
