The fossil endocarps agree closely with this Chinese and Japanese species (fig. 18), 

 though in some specimens the large foramen is less marked. The best specimens 

 showing the open foramen unfortunately are crushed laterally and do not make satis* 

 factory photographs. The species is common at Reuver, but has not been found at the 

 other localities. 



CORNUS Sp. 2. 

 PI. XV, fig. 19. 



Endocarp small globose slightly pointed at apex ; with regular scarcely prominent 

 ribs, and narrow strands of fibres ; foramen shallow and simple. 



Length 3.3 mm., breadth 3.3 mm. Swalmen. 



This is the only specimen of Covnus found at Swalmen, and it is flattened by 

 pressure. It differs from the C. controversa of Reuver in being thinner walled, and in 

 the greater regularity and the obscurity of its ribs. It may be unripe ; but it does not 

 seem to belong to C. controversa, and no similar fruits have been found at Reuver. 



CORNUS cf. MAS Linn. 

 PI. XV, fig. 20. 



Endocarp (broken) ovate; ribs numerous sharp branching. 



Length 7.5 mm., breadth 4.0 mm. Brunssum. 



A somewhat damaged endocarp of elongate*ovate shape suggesting C. mas of 

 Europe, or the allied C. officinalis of Korea. More material is wanted for exact deter* 

 mination. 



CORNUS Sp. 



PI. XV, fig. 21. 



Endocarp small elongate; ribs about 5 prominent sharp. 



Length 5 mm., breadth 2 mm. Brunssum. 



A damaged endocarp somewhat resembling the last, but much smaller and 

 with fewer ribs. 



HELWINGIA Sp. 

 PI. XV, figs. 22, 23. 



Pyrene oblong, wedge*shaped, ventrally angled, longitudinally grooved; dorsally 

 tubercled coarsely; opening large sunk gaping. 



Length 6.0 mm., breadth 2.7 mm. Swalmen. 



In size shape and character of the micropyle this pyrene bears a close resem* 

 blance to Helwingia himalayaca Hook. f. et Thoms; but the sculpture is different and
