GLANDULINA REUSSI Cushman and Ozawa, new species 



Plate 40, figures 2 a, b 



Psecadium acuminatum Reuss, Sitz. Akad. Wiss. Wien, yol. 62, pt. 1, 1870, 

 p. 478. — V. ScHLiCHT, Foram. Pietzpuhl, 1870, pi. 25, figs. 1-10. 



Test elongate, fusiform to cylindrical, circular in section, greatest 

 breadth near the apertural end, distinctly acute toward the initial 

 end; chambers rounded, arranged in an entirely uniserial series; 

 sutures not depressed, distinct; wall smooth, translucent; aperture 

 often with an entosolenian tube, which is visible from the exterior, 

 radiate. 



Length of holotype 0.43 mm.; breadth 0.18 mm. 



Holotype. — (Cushman Coll. No. 11884.) From the Oligocene of 

 Pietzpuhl, Germany. 



The present species is fairly well figured by v. Schlicht under the 

 name of Atradolina, to which Reuss gave the name Psecadium acumi- 

 natum, but we include it in Glandulina. The name acuminata is 

 preoccupied by d'Orbigny, and accordingly the new specific name 

 reussi is proposed. 



Distribution. — We have only a single specimen from the Oligocene 

 of Pietzpuhl, Germany, the type locality.

 Polymorphina vitrea Bornemann var. glandulinoides Fornasini, Mem. 



Accad. Soc. Istit. Bologna, ser. 5, vol. 9, 1900-1902 (1902), p, 66, 



fig. 18 (in text). 



Test fusiform (young microspheric form) to cyhndrical (adult), 

 acuminate (microspheric) or rounded (megalospheric) at the initial 

 end; chambers inflated, arranged in a nearly triserial series in the 

 young, becoming uniserial later in the microspheric form, or entirely 

 uniserial, but not regularly so in the megalospheric form; sutures 

 slightly depressed, generally distinct; wall smooth; aperture radiate. 



Maximum length 1.20 mm.; diameter 0.44 mm. 



The present species is undoubtedly derived from Pyrulinafusiformis. 

 'The early stage of the microspheric form of Glandulina dimorpha re- 

 sembles Pyrulina Jusiformis, yet its septa even in the young state 

 tend to be placed at right angles to the exterior wall.
