Original Description

Test almost  spherical, comprising  a trochoidal  Globigerina, 4  chambered  in its  last  stage,  and  a  composite  supplementary  chamberlike  growth  on  the  umbilical  side:  consisting  of  a  single, large, inflated ,  primary  "chamber" across  the  umbilicus  and  of  3  small  only  slightly  inflated secondary "chambers." 
Aperture of  the  Globigerina  stage  prior  to  the  formation of the supplementary  growth not  known,  probably single,  large arcuate aperture characteristic  for this  type  of  Globigerina. 
Late  ontogenetic  aperture  multiple, with  maximum  9 small semicircular openings  in  the secondary  "chambers." 

 


Extra details from original publication
Remarks.-Globigerinatheka is  monotypic, and  can  be  distinguished  from related genera  by  the Globigerina  test formed  prior to  the umbilical  supplementary  growths, which  is  composite  in  structure.
