Test subglobular, the base broadly rounded, apertural end produced 

 and regularly acuminate, the sides straight and not concave, typically 

 rounded in end view; chambers few, extending back almost to the 

 base; sutures not depressed; wall smooth; aperture radiate, sHghtly 

 produced. 



Length, 0.55-0.75 mm.; breadth, 0.40-0.55 mm.; thickness, 0.40- 

 0.55 mm. 



We do not deny that the Cretaceous GlobuUna lacrima is very close 

 to and almost identical with Tertiary and Recent GlobuUna gibba. 

 If, however, we should examine GlobuUna lacrima, or Cretaceous 

 GlobuUna gibba identified by other authors, we would be surprised to 

 find all specimens constant in their characters. The apertural end 

 is definitely produced. The Cretaceous specimens of both Europe 

 and America that we have examined are constant in this character. 

 Among Tertiary and Recent GlobuUna gibba there are some which 

 have a produced aperture as in GlobuUna gibba var. pyrula Egger, but 

 in this case the side is always concave instead of straight as in G. 

 lacrima. Polymorphina longicollis Karrer is described as having a 

 compressed test, and may be distinct from the present species. Poly- 

 morphina ovulata Dunikowski, judging from the figure, appears to be 

 a young stage of Marginulina; but if it be GlobuUna, it would be 

 related to GlobuUna lacrima. 



DistribuUon. — The geological range seems to be limited. We 

 have specimens from the Cretaceous, both of America and Europe. 

 The localities are: England, chalk marl, Folkestone; Saxon Cement
