many years in Malaya, he at once pointed out their resemblance to the anonaceous 

 seeds which in Malaya are scattered everywhere by birds. At first we could not trace the 

 curious partial septa, passing between the folds of the ruminate albumen, which are 

 so characteristic a feature of the Anonaceae; but at length we discovered several sped* 

 mens showing clearly the remains of these septa, which are very thin and fragile. As, 

 however, these fossil seeds will not fit in with any living anonaceous genus, we are 

 compelled to institute for them a new one, which we name after the discoverer of the 

 specimens, Dr. W- J. Jongmans. 



Fructus (baccatus?), compactus, e carpellis tribus unispermis constitutus; 

 semina parva, testa dura osseaque. 



Fruit compact, of 3 l*seeded carpels (a berry?); seeds small, testa very hard 

 and bony. 



JONGMANSIA CYPREAEFORMIS Sp. Nov. 



PI. VIII, figs. 14—21. 



Semina parva, cypreaeformia, plus MINUSVE LATERIBUSANGULATA, TESTA CRASSIS* 

 SIMA OSSEA INTUS INCOMPLETE PLURIsSEPTATA. 



Seeds small, cypreaeform, more or less facetted lateraly by mutual pressure 

 (figs. 14—17), occassionally adhering laterally (figs, 18, 19); testa very thick and bony 

 (fig. 21), showing internally numerous partial septa (figs 20, 21). 



Length 4 mm., breadth 3 mm. Reuver, Swalmen. 



It is not easy to make out the position of this curious genus within the family, 

 for it does not seem to belong to any recognised section. The mutual facetting, and 

 occassional lateral adhesion, of the seeds suggest that the carpels were united into a 

 single syncarpous fruit, only slightly succulent. In short, they were specially modified 

 for dispersal by small birds. This seems to be borne out also by the minuteness of the 

 seeds and the exceptional thickness of their testa. Few, if any, living Anonaceae have 

 seeds so small and hard as these. 



The Anonaceae at the present day form a large family, essentially tropical, with 

 only a few stragglers into warm*temperate regions. None live in Europe. 



LAURACEAE. 



CINNAMOMUM Sp. 1. 

 PI. VIII, figs. 22 a, b. 

 Two cupules of cinnamon have been found at Reuver and one at Swalmen ; but 

 the three specimens belong to three species, none of which agrees with any of the 

 cupules found in Miocene deposits and figured by Oswald Heer. 



Cup large open, suddenly contracted below into a narrow stalk of nearly 

 uniform width. 



Length 7 mm., breadth 7 + mm. Swalmen.
