of the " Archiv. naturw. Landesdurchforsehung von Bohmen," Professor 

 Anton Fric commenced the publication of his monumental studies of the 

 Bohemian Cretaceous (Studien im Gebiete der bohmischen Kreide forma- 

 tion-Paleontologische untersuchungen der einzelnen schichten in der 

 bohmischen Kreideformation) during the progress of which he has been 

 assisted in the study of the fossil plants first by Feistmantel, then by 

 Velenovsky, and in later years by Bayer. The first of these studies, 

 published in I860, 1 is devoted to the structure, lithology, areal distribu- 

 tion, and flora and fauna of the Perucer beds. The second published in 

 1877 2 treats of the Weissenberger and Malnitzer beds. 



With the exception of Fric's work just mentioned and the three 

 species described by Saporta 3 from the Perucer beds, nothing beyond 

 the frequent mention of Cretaceous plants from Bohemia in general 

 works appears until the year 1881 when Velenovsky 4 in a preliminary 

 paper announced his extensive studies on the flora, which commenced to 

 appear the next year. His discussion of the dicotyledonous plants came 

 out in four parts in Band ii (1882), iii (1883), iv (1884), v (1885), of 

 the " Beitrage zur Palaontologie Oesterreichungarns und des Orients," von 

 Mojesisovics und Neumayr, under the title of " Die Flora der bohmischen
