 PSEUDOPOLYMORPHINA ZEUSCHNERI (Reuss) 



Plate 25, figures 5 a-c 



Polymorphina zeuschneri Reuss, Sitz. Akad. Wiss. Wien, vol. 56, pt. 1, 1867, 

 p. 90, pi. 4, fig. 1. 



Test oblong to more or less fusiform, compressed, broadest at the 

 upper half, rather acute at the initial end; chambers rounded, com- 

 pressed, arranged in a biserial series; sutures depressed but little, 

 distinct; wall smooth; aperture radiate. 



Length of figured specimen 0.80 mm; breadth 0.50 mm.; thickness 

 0.30 mm. 



The specimen described by Reuss comes from "Salzthon" and 

 "Steinsalz" in Galicia. We have a specimen from the Miocene of 

 Varpolata in Hungary which is not much different in its foraminif- 

 eral fauna from the formation in Galicia. 



Polymorphina consecta d'Orbigny, figured later by Fornasini, is 

 from the Miocene of Dax and shows a close resemblance to the present 

 species. 



PSEUDOPOLYMORPHINA INDICA (Cusl.man) 



Plate 25, figures 7 a, b 



Polymorphina prohlema d'Orbigny var. indica Cushman, Bull. 100, U. S. 

 Nat. Mus., vol. 4, 1921, p. 265, pi. 52, figs. 1, 2; pi. 53, figs. 1 a, b. 



Test large, broad, oblong, but little compressed; chambers inflated, 

 rounded, arranged at first in a quinqueloculine series, later becoming 

 more or less biserial; each succeeding chamber removed farther from 

 the base; sutures much depressed, distinct; wall thick, that of earlier 

 chambers and the posterior half of the later ones with fine longitu- 

 dinal costae; aperture radiate. 



Maximum length 2.50 mm.; breadth 1.60 mm.; thickness 1.00 mm. 



The present species is close to Guttulina regina from which it is 

 evidently derived by losing the quinqueloculine arrangement of 

 chambers. The surface ornamentation is not definite, and that of 

 the later chambers is often obscured. 



Type specimen (Cat. No. 16056, U.S.N.M.) from Albatross Station 

 D5579, off Sibuko Bay, Borneo, in 75 fathoms (320 m.). 



Distribution. — We have three specimens from the type locality. 

 "The species also occurs at the neighboring Albatross Station D5580, 

 off Sibuko Bay, in 162 fathoms. A single specimen from off Amino, 

 Japan, completes the known distribution.
