Terquem's GuUulina austriaca var. angusta and Polymorphina dispar 

 are also placed in the synonymy of the present species. The former 

 has a slightly shorter test. 



The latter appears to have one or two more chambers than the 

 usual specimens of Polymorphina praelonga. 



Polymorphina cylindrica Prochazka having a cylindrical test 

 consisting of rather short chambers, is not much different from Poly- 

 morphina angusta or Polymorphina austriaca var. angusta Terquem. 



Distribution. — Egger's types are from the Miocene. We have a 

 paratype of Egger's from Ortenburg. The species occurs also in 

 the Miocene of France at Dax and Le Coquillat, Leognan, France, 

 as well as in the upper Oligocene (Stampien ) of Jeurs, France. All 

 these localities have a fauna very closely related to that described 

 by Egger. Somewhat similar specimens occur in widely different 

 localities such as the upper end of Buzzards Bay, Mass., Kobama, 

 Japan; Wool Bay, Yorkes Peninsula, west side of St. Vincent Gulf, 

 Australia. Somewhat similar specimens occur in the Pliocene of 

 Fiji and in the Eocene of the Isle of Wight, England, Grignon and 

 Parnes (Les Boves), France, and in the Jackson of the United States. 

 It is probable that these do not all represent a single species, but the 

 specimens have a very similar arrangement and shape of the chambers. 

 Some are clockwise and others contraclockwise in their arrangement, 

 but the distinction does not seem to be constant. 



GUTTULINA GUTTIFORMIS (Terquem) 



Plate 6, figures 9 a-c 



Polymorphina guttiformis Terquem, Mem. Soc. Geol. France, ser. 3, vol. 1, 

 1878, p. 42, pi. 9 (14), fig. 24 a, b. 



Test slender, in front view an isosceles triangle, broadest at the 

 ba,se, tapering toward the apertural end; chambers cylindrical, 

 arranged in a quinqueloculine series, but little embracing, all extending 

 back nearly to the base; sutures depressed, distinct; wall smooth; 

 aperture radiate. 



Length 0.65-0.90 mm.; breadth 0.25-0.35 mm.; thickness 0.16-0.24 

 mm. 



This is one of the well marked species of Guttulina. Its test is 

 elongated, but it is quite different from other elongate Guttulinas 

 characterized by a botryoidal test, in having the chambers all extend- 

 ing down to the base. The nearest ally of the present species is 

 Guttulina praelonga in which the chambers are much more inflated. 



Distribution. — We have specimens from the following localities: 



Miocene. — Burdigalien, France, St. Paul de Dax; Moulin de 

 I'Eglise, Saucats. 



Oligocene. — Germany, Ahnatal, near Cassel; Hildesheimer Wald, 

 Dickholzen, Hanover.
