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 0.08 mm. and is granulated 
transversally. 
Occurrence .—Lower Miocene (Bowden horizon): Rio Gurabo, Santo Domingo 
(rare). 
Habitat .—Andaman or Nicobar Islands? (Levinsen); Tortugas Islands, Florida 
(Osburn). 
Plesiotype. —Cat. No. 68482, U.S.N.M.
