uneven back-surface and two plane or slightl) concave sides meeting together 

 in Ihe »ventrah line. 



There is no cavitj internallj in these carpolites; the carpolite has through- 

 oul ;i characteristic, vesiculated structure. The si/c varies from 3. 8. mm. 

 in length and corresponding breadth. 



Whilsl such carpolites in form like sections rrom a sphere are very 

 common in Ihe amber-pin-beds, il is a greal raritj !<> meel with several 

 of them connected together; Rosenkjær's reports oi discoveries, which 

 record these carpolites under the name of »carbonized kernelsa, mention 

 however ;it several piaces tli;it thej originally held together bul later sep- 

 arated <m preparation. In the material gone through by rae one case was 

 found of 3 wedge-shaped pieces united to Form a hall sphere, which showed 

 ;i fainl depression at one end surrounded bj a low, ring-shaped elevation; 

 in the material From Valbj Bakke lastlj the spherica] shaped carpolite re- 

 presented in fig. 2 and Formed of 6 connected pieces was Found; a section 

 shows 6 small chambers containing remains <>r the seed-test; in the material 

 From Itzehoe a similar whole carpolite with 6 chambers was also Found. 



I Found the same carpolite (fig. 1) on a visil in 1898 to the Victoria pil 

 al Senftenberg (Niederlausitz). 



This carpolite, to which in 1906 I gave the name C. Valbyensis (in Rosen- 

 kjær: Fra det underjordiske Kjøbenhavn«), was in the same year (1906) 

 cailed Elæocarpus globulus by Menzel; according to the latter the fruits are 

 common along with the leaves, which show a complete agreemenl with 

 leaves of the E. alaternoides Brongn. et ('.ris of the present day. The 1 ru i t 

 is lims described: Fructibus drupaceis, globulosis; pericarpio verisimiliter 

 coriaceo, putamine duro, sphæerico, quinque-loculari, longitudinaliter punctato. 

 The two specimens I have Found in the amber-pin-beds are however six- 

 chambered, not five-chambered. Even before I became aware of Menzel's 

 paper I had remarked upon the resemblance between this fruit and the E. 

 sphæricus Gartn. (recent) figured by Heer ( 18(»9 >, which is however much 

 larger, and /•.". Albrecht HEER. 



Elæocarpus is a genus belonging to the Tiliaceae and lives at the present 

 time in tropical Asia, Australia, the Pacific istands, New Caledonia and Japan. 



Stratiotes aloides (PI. IV. Rgs. 3— 1). As the seed of this species occurring 

 in the amber-pin-beds lias a more tuberculated surface than the typical 

 interglacial and now-living seed and thus forms a transition to the Tertiary 

 S. Kaltennordhemensis, I have called it .S', aloides F. intermedia (I have Found 

 the smile form in the preglacial beds at Kime in Hanover mentioned by II. 

 Menzel (1906, p. 623)). 



Age of the amber-pin-beds. 



( Rav-Pindelagenes Alder.) 



Like several other authors who have taken up this question, the present 

 author is inclined to consider the flora of the amber-pin-beds as predomin- 

 antly preglacial. 



On the other hånd, the amber-pin-beds are themselves of pleistocene age, 

 formed at the same time as the deposits of the sand in which the plant- 

 remains are now found on a secondarv hed.
