4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 126 



Derivation. — rectus L. straight, upright + glandula L. dim. acorn 

 (shaped). Gender feminine. 



Diagnosis. — Test free, uniserial, with chambers increasing rapidly 

 in diameter and strongly overlapping, sutures horizontal and parallel, 

 never strongly depressed ; wall calcareous ; aperture terminal, radiate. 



Remarks. — This genus differs from Glandulina d'Orbigny in lack- 

 ing an early biserial stage, and from P seudonodosaria Boomgaart in 

 having all chambers closely appressed and with the later chambers 

 unseparated by constricted sutures as are found in P seudonodosaria. 

 It includes many of the species previously placed in Pseudoglandulina 

 Cushman, 1929, but does not include the type species of Pseudo- 

 glandulina, Nautilus comatus Batsch, which has been shown to belong 

 to the genus Nodosaria Lamarck, 1812.
