ART. 6 FORAMINIFEEA: POLYMORPHINIDAE — CUSHMAN AND OZAWA 103 



As remarked in the case of the typical form, Terquem's species, 

 Polymoryhina fischeri, contains both smooth and ornamented forms. 

 The form having a smooth surface is described and figured before the 

 ornamented form, which coincides with Pseudopolymorphina variata. 

 Therefore Terquem's specific name jischeri is used as a varietal name 

 for the smooth variety of P. variata. 



Jones included a smooth variety from the Crag in Polymorphina 

 compressa, but their difference is very conspicuous. The present 

 variety has compressed but more rounded chambers instead of elon- 

 gated chambers as in Polymorphina compressa. 



Polymorphina dilatata listed by d'Orbigny and figured by Fornasini, 

 considered from the figure, is very close to the present variety. 

 Polymorphina lecointreae Allix, as reported from the Miocene of 

 Touraine, has rather rounded chambers separated by more or less 

 depressed sutures, and may be included in the range of variation of 

 the present variety. 



Some figures of Guttulina racemosa Terquem described in the same 

 paper as the present variet-y appear to be very similar to a young stage 

 of the present variety. They are probably young specimens. Two 

 specimens somewhat resembling Terquem's Guttulina racemosa are 

 figured. 



Distribution. — The present variety generally occurs associated with 

 the typical form, and it seems to be limited to the late Tertiary of 

 Europe. The localities of our identified specimens are as foUows: 



Pliocene.— Crag, of Suffolk, England. Isle of Rhodes. 



Upper Miocene. — Pontlevoy, France; near Bordeaux, France.

 p. 233, pi. 13, figs. 1-3 (not of 1826).— H. B. Brady, Rep. Voy. Chal- 

 lenger, Zoology, vol. 9, 1884, p. 564, pi. 72, figs. 7, 8. — Cushman, Bull. 

 104, U. S. Nat. Mus., pt. 4, 1923, p. 151, pi. 40, figs. 11, 12. 



Test fusiform, more or less compressed, elliptical in end view; 

 chambers inflated, much embracing, arranged in a nearly biserial 

 series, each succeeding chamber not much removed from the base; 

 sutures but little depressed, fairly distinct; wall smooth; aperture 

 radiate. 



Length 0.85 mm.; breadth 0.65 mm. 



D'Orbigny's Polymorphina ovata, described in the Vienna mono- 

 graph, is evidently different from Polymorphina (Globulina) ovata, 

 named in 1826, but was neither figured nor described by d'Orbigny. 

 Polymorphina ovata, therefore, as a specific name can not be used, and 

 a new name ovalis is proposed.
