 Polymorphina fusiformis Chapman (not Roemer), Journ. Roy. Micr. Soc, 



1896, p. 11, pi. 2, fig. 9 (not fig. 10). 



Test elongate, fusiform, more or less compressed, acuminate toward 

 both ends; chambers elongate, tapering to the base, arranged in an 

 almost triserial series; sutures but little depressed; wall smooth; 

 aperture radiate. 



Length, 0.50-0.80 mm.; breadth, 0.25-0.35 mm.; thickness, 0J.8- 

 0.27 mm. 



This is one of the more common species among the Cretaceous 

 Polymorphinidae. It resembles compressed Glohulina minuta in the 

 Tertiary, with which it may be confused, but Glohulina prisca is 

 always compressed and usually very slender, its later chambers gen- 

 erally coming down almost to the base, while in Glohulina minuta the 

 test is as a rule typically fusiform with a circular section and the later 

 chambers removed farther from the base. 



As Olszewsld's Polymorphina acuta is not well drawn, we can not 

 be positive without seeing the types, but it seems to be very close to 

 Glohulina prisca. 



Distribution. — This species is fairly common in the Cretaceous of 

 Europe and America. We have specimens as follows : 



Cretaceous. — England, Cambridge greensand, Saxon Cement Works, 

 Cambridge ; chalk marl, Saxon Cement Works, Cambridge and Folke- 

 stone; lower Gault, Barnwell pit, Cambridge, and bed VI, Gault of 

 Folkestone. Germany, upper Senonian. Dasbeck b. Hanover, West- 

 phalia. Mexico, numerous specimens from Upper Cretaceous, 

 Velasco shale. Hacienda El Limon, west of Panuco.
