II. 1). Brady* infers that the Carboniferous species placed under Cribrostomum by 

 Moller belong to Textulana and Bigenerina, and the latter name is adopted by 

 Dr H. Yabe t for Cribrostomum bradiji Moller. 



" Cribrostomum " gracile Moller. 



Moller, loc. ait., 1879, pp. 59, 60, fig. 23, pi. iii. fig. 4. 



The examples at hand appear quite typical, but I have not observed any showing 

 the uniserial mode of growth, and none attain the maximum size of the Russian 

 specimens. 



Genus Tetrataxis Ehrenberg. 



Tetrataxis gibba Moller. 



Moller, loc. cit., 1879, p. 73, pi. ii. fig. 4, pi. vii. fig. 3. 



As regards shape and size the few examples observed agree in every respect with the 

 original definition of the species. 



Genus Arch^ediscus Brady. 



Archsediscus karreri Brady. 

 Brady, Monograph of Carboniferous and Permian Foraminifera, Pal. Soc, 1876, p. 142, pi. xi. figs. 1-6. 



This species is very abundant, and the specimens average 1 mm. in diameter, being 

 thus appreciably larger than the Russian examples known to Moller. 



Genus Fusulinella Moller. 



Fusulinella struvei Moller. 



Moller, loc. cit., 1879, p. 22, pi. ii. fig. 1, pi. v. fig. 4. 



Fusulinella struvei is represented by numerous specimens in various stages of 

 growth, agreeing remarkably well with the Russian form as delineated by Moller. 



Genus Lagena Walker. 

 Lagena ? sp. indet. 



Small flask-shaped bodies may possibly be referable to some species of Lagena, but 

 as they were observed in thin sections only, they had better be left unclassified, even 

 generically.
