Variety differing from the typical in the development of a distinct 

 basal spine. 



Length including spine 0.50-0.65 mm.; breadth 0.30-0.46 mm.; 

 thickness 0.18-0.30 mm. 



Holotype of variety. — (Cushman Coil. No. 11209.) From the Cre- 

 taceous, chalk marl of Folkestone, England. 



This variety is abundant in our collections from the chalk marl 

 and Cambridge Greensand of the Saxon Cement Works, at Cambridge, 

 England. Burrows, Sherborn, and Bailey's specimen was from the 

 Red Chalk in England. We also have it from the lower Cenomanian, 

 Tecklenburg Wald, Westphalia, Germany,

Test elongate, more or less cylindrical, broadest below the middle, 

 tapering toward the aperture, rounded at the initial end; chambers 

 elongate, clavate, arranged in a quinqueloculine series, not much em- 

 bracing; sutures depressed, distinct; wall smooth; apertural end often 

 with fistulose tubes; aperture radiate. 



Length 0.45-0.95 mm.; breadth 0.22-0.38 mm.; thickness 0.10-0.16 

 mm. 



We have examined a paratype specimen of Egger's Polymor'phina 

 praelonga and are convinced that it is identical with Polymor'phina 

 angusta described by him in the same paper. Egger's Polymorphina 

 praelonga is a full-grown specimen having one or two more chambers 

 than Polymorphina angusta. The figures of Polymorphina praelonga 

 Egger show the chambers arranged in a biserial series, but they are 

 undoubtedly not well drawn. 



Terquem figured and described Polymorphina praelonga in 1878, 

 which is the same as Polymorphina angusta Egger.
