 NODOSARIIDAE (FORAMINIFERA)

In 1839 d'Orbigny described Glandulina as a subgenus of Nodo- 

 saria (type species Nodosaria (Glanduline) laevigata d'Orbigny, 

 1826). This type species has a biserial early chamber arrangement 

 and, as was shown much later, also an internal tube connecting with 

 the radial aperture. 



For many years all uniserial forms with strongly overlapping 

 chambers were placed in this genus. In 1929 Cushman proposed a 

 new generic name, Pseudo glandulina, for the completely uniserial 

 forms, leaving in Glandulina those species which, like the type species, 

 have an early biserial chamber arrangement. Perhaps because the 

 early stages are not always clearly visible, in recent years the generic 

 names Glandulina and Pseudoglandulina have both been rather 

 loosely applied, many completely uniserial forms being left in Glan- 

 dulina and some with a biserial stage and internal tube were placed 

 in Pseudoglandulina. Some authors even placed the species laevigata, 

 the type of Glandulina, in Pseudoglandidina, although d'Orbigny's 

 name had nearly a century's priority. 



The type designated by Cushman for the genus Pseudoglandidina 

 was Nautilus comatus Batsch, but as will be shown in the generic 

 discussion that follows, this form is actually a Nodosaria; hence the 

 name is a junior synonym. As a new name is therefore needed for 

 the uniserial, rectilinear Glandidina-Viko. species, one is here proposed. 



Recently, Boomgaart (1949) proposed the name Pseudonodosaria 

 for the rectilinear Glandulina-like species which show a tendency to 

 become like Nodosaria in the adult, with inflated, less-embracing
