Oligocene and Miocene Globigerinita glutinata have commonly been described under the designation Globigerina juvenilis Bolli, 1957 (the holotype of which is middle Miocene). We illustrate here new SEMs of the holotype of juvenilis (Plate 16.2, Figs. 5-7) and confirm that it is a microperforate form that falls within our concept of glutinata .
