chambers and constricted sutures. A description is here given of an 

 American species we consider to belong to this genus. 



During the course of these investigations we found specimens of 

 a Glandulina-likQ form that differed from those mentioned above in 

 having a uniserial chamber arrangement, but with a curved axis, some- 

 what as in Marginulina and with strongly embracing chambers. A 

 new name has been here proposed to include this new species and 

 some earlier described species formerly referred to Glandulina. 



The three genera here considered should be classed with the Nodo- 

 sariidae, as they have a hyaline calcareous wall and radial aperture 

 and show neither a biserial early stage nor an internal siphon. 



Unfortunately, it is impossible to determine from the literature to 

 which of these genera each described species should be referred, as 

 many writers have ignored the early portions of their species in both 

 figures and descriptions and few have shown the internal characters. 

 Many of the species must be critically re-examined to determine 

 whether they should be placed in Glandulina, Pseudonodosaria, or in 

 one of the two genera here named, Rectoglandulina or Pandaglan- 

 dulina.

Discussion. — Cushman (1929, p. 87) defined Pseudo glandulina as 

 similar to Nodosaria but with embracing chambers, and as differing 

 from Glandulina in lacking the early biserial "pyruline" stage. Cush- 

 man designated Nautilus comatus Batsch, 1791, as type species of 

 Pseudo glandulina. 



Batsch (1791, pi. I, fig. 2a-d) originally figured two completely 

 different types as Nautilus comatus. One of these was a typical 

 Nodosaria (fig. 2a, b) and the other a Glandidina (fig. 2c, d). Ap- 

 parently it was the latter form to which Cushman referred. How- 

 ever, Parker, Jones, and Brady (1865, p. 226) had earlier recognized 

 these distinct differences in Batsch's figures, and they had already 

 designated Batsch's fig. 2a, b, as Nodosaria comata (Batsch) (al- 

 though stating that this was a "smallish specimen of Nodosaria 

 raphanus"), and they referred Batsch's fig. 2c, d, to Glandulina glans 

 d'Orbigny. Thus when Cushman designated Nautilus comatus Batsch
