1 hc Introduction (pp. 1—11) gives a brief review of the earlier literature 

 concerning the phytopalaeontological discoveries in the Rhætico-liassic, Cre- 

 taceous and Tertiary deposits of Denmark. 



On pp. 6—8 a list is given aceording to Stolley (1899) of the diatoms 

 found in the Tertiary »Cementsten« and Diatom-earth of the Limfjord. 



Tertiary deposits. 



(Tertiære Alle j ringer.) 



Cementstone. 



(Cementsten.) 



In the section: Tertiary deposits first the »Cementsten« and its 

 plant remains are deserihed (pp. 12—18); of greatest interest are leaves 

 of Cocculites Kanei, figured on PI. I, tig. 1 and PI. II, fig. 1, formerly known 

 from Greenland, Belgium, Ireland and the Hebrides, from beds which are 

 most probably Eoeene. 



The following new species wcre found: Carpolithes Furensis m. (PI. II, fig. 3) 

 is a 3 mm. long, 2 mm. broad, egg-shaped, slightly eompressed carpolite, 

 which is provided at both ends with a low, rounded tip; from tip to tip 

 there are 8 fine, light, longitudinal stripes on the dark-brown, thin shell, 

 which seems to have a tendency to split into hvo halves. 



Carpolithes sphæricus, a spherical carpolite, is ca. 7 mm. in diameter, 

 filled with calcspar; the testa is ca. O.s mm. thick, of a darker colour; frag- 

 ments of a black, smooth shell of coal, thin as paper, cover the surface of 

 the carpolite, on which there is also a low, faintly rounded tip; the resem- 

 blance with the fruits of recent Lindera and Cinnamomum is exceedingly great. 



In connection with the plant remains in the Danish »Cementsten« two 

 carpolites are deserihed, which were found in a septarium-like knoll at 

 B rot hen (Holstein) by Stolley (1899, p. 106 et seq.); this knoll further 

 contained various animals (Valvatina rhaphistoma, Stolley), elytra of beetles 

 (Erirhinus sp.?, PI. Ik fig. 4), Carp. sphaericus and Carp. rhabdospermns (Lesq.) 

 m. (PI. II, fig. 5) the last earlier known from the Tertiary lignite (Eoeene or 

 Miocene) at Brandon (Vermont, U. S. A.). 



The »Cementsten« is regarded as Eoeene.
