ART. 6 FORAMINIFERA: POLYMOHPHINIDAE— CUSHMANAND OZAWA 33 



Distribution. — This variety has occurred in considerable numbers 

 at various stations off the Dry Tortugas, off Florida, and off Cuba. 

 Specimens of very similar character and seemingly identical occur 

 in the Eocene, Bracklesham beds XVII and XVIII, Isle of Wight, 

 England, and in the lower Oligocene, Byram marl of Byram, Miss. 



GUTTULINA HANTKENI Cushman and Ozawa, new species 



Plate 5, figures 4-6 

 Polymorphina acuta Hantken, Mitth. Jahrb. K. Ungar. geol. Anstalt, vol. 4, 

 1875 (1881), p. 60, pi. 8, fig. 4 {acuminata on explanation of plate). 



Test oval, botryoidai, more or less rounded at the base, acute at 

 the aperture, greatest breadth above the middle; chambers ovate, 

 embracing but little, arranged in a contraclockv/ise, quinqueloculine 

 series, each succeeding chamber removed farther from the base 

 sutures much depressed, very distinct; wall smooth, thick; aperture 

 acutely produced, radiate. 



Length 0.60-1.20 mm.; breadth 0.35-0.75 mm.; thickness 0.30- 

 0.60 mm. 



Holotype. — (Cushman Coll. No. 11194.) Eocene, Kleinzellen, bei 

 Of en, Hungary. 



Guttulina hantkeni has a typical botryoidai test consisting of ovate 

 chambers, while other botrj^oidal species such as Guttulina austriaca 

 and Guttulina spicaeformis have invariably more slender tests con- 

 sisting of clavate chambers. 



The Cretaceous Polymorphina uviiormis Eeuss, which is included 

 in Guttulina spicaeformis (Koemer) in this paper, seems to represent an 

 intermediate form between Guttulina hantkeni and Guttulina spicae- 

 formis. Both Hantken's names, Polymorphina acuta, and Polymor- 

 phina acuminata, given to the present species, are preoccupied; 

 therefore a new specific name is proposed, named for Doctor Hantken. 



Distribution. — Guttulina hantkeni seems to be limited in its geologi- 

 cal distribution. Our specimens were obtained from the Eocene for- 

 mations of Neustift, Ofen, Hungary, the type locality of Hantken's 

 specimens, also from the middle Eocene of the United States, Clai- 

 bornian, of New Jersey and Louisiana. We also have specimens from 

 the upper Senonian of Maastricht, Holland, which are very similar.
