The great Carboniferous Limestone has long been known to contain, 

 and indeed in places to consist of, Foraminifera, often of relatively 

 large size. Fischer de Waldheim indicated the Fusulina, which Car- 

 penter rightly removed in classification from the Imperforata to the 

 Perforata group, and which H. B. Brady further elucidated and now 

 refers to the Eotaline series. Ehrenberg illustrated several allied 

 forms (Borelis &c.), which Parker and Jones (treating of his ' Mikro- 

 sceologie ') interpreted and put into a regular series. He figured 

 also other Foraminifera associated with the former. John Phillips 

 long ago pointed out the leading Eadothyra, of which genus nume- 

 lous representatives are now known from fl. B. Brady's researches. 

 llouiUier, Vosinsky, and d'Eichwald added some of these and other 

 forms ; and Brady has not only interpreted these, but augmented 

 the list with numerous highly important and weU-systematized 

 genera and species. All this fauna, excepting Fusulina, he describes 

 and figures (44 species in 14 genera) in his " Monograph of the 

 Carboniferous and Permian Foraminifera," Palseontogr. Soc, 1876. 



In Professor Valerian von Mclller's two memoirs before us we 

 have some of the same or very similar forms (occurring in Russia), 

 together with the Fusidince (in 4 genera with 14 species), treated of 

 as 14 genera with 41 species. 



These two elegant monographs are illustrated with numerous 

 well-drawn, though sometimes bold and somewhat diagrammatic 

 figures, altogether making twenty-two quarto plates, of the very 

 interesting Foraminifera found in the Carboniferous Limestone of 

 Russia, and, in most cases, of other countries also. Numerous clear 

 woodcut diagrams, moreover, illustrate the text. The descriptive 

 portions of these monographs bear evidence as well to great acumen 

 and industry (indeed, energy and enthusiasm) on the part of the 

 author, as to much friendly help and sympathy from his scientific 

 colleagues and friends. The result has been a revision of what has 

 been done in elucidation of this particular branch of palaeontology 

 among the Rhizopoda obtained from one of the latest of those which 

 geologists term " primary " or " palaeozoic " strata. This rcTision, 

 howcTcr, has been ruled by views differing considerably from those 

 of the observers who have preceded Prof, von Moller in this parti- 

 cular line of research. Examining with close attention the intimate
