This endocarp seems to have been nearly terete in section, as it is crushed at 

 right=angles to the suture. It greatly resembles that of Prunus Ramburii of the Sierra 

 Nevada, California, and is of the same size though somewhat narrower. The endocarps 

 of P. Ramburii in the Kew Herbarium are unripe, but seem to be differently sculptured. 

 We have only one specimen of the fossil. 



PRUNUS SPINULOSA Sieb. et Zucc. 

 PI. IX, figs. 26-28. 



Endocarp oval, pointed above and below, moderately keeled, thin; sculpture 

 2 or 3 strong loops towards the upper end and large cord*like reticulations. 



Length 10.5 mm., breadth 6.0 mm. Reuver. 



The only difference we can see between our fossils and the living Japanese species 

 (fig. 28) is that the surface sculpture is more conspicuous in the recent endocarps, and 

 that the fossil endocarps are flat. The flattening of the endocarps is obviously due to 

 crushing, for some specimens are crushed from side to side, others edgeways. All our 

 specimens are a good deal eroded, as though they may have been washed from some 

 distant mountains, and this has often destroyed the smaller reticulation though the 

 larger loops may be preserved. 



PRUNUS STIPITATA Sp. nov. 

 PI. IX, figs. 29-31. 



Endocarpium inflatum, ovoideum, apice acuminatum, breviter stipitatum; 

 superficies inferne prominenter longitudinaliter plurisjugata, superne crasse irre* 

 gulariter reticulata. 



Endocarp inflated, oval, pointed above, shortly stipitate below; sculpture several 

 strong longitudinal ridges below, coarse irregular reticulation above. 



Length 8.0 mm., breadth 5.0 mm. Reuver. 



Only the three figured specimens of this species have been seen. The most curious 

 characters will be found in the short stalk, up which the channel of the raphe passes 

 (well shown in fig. 30), and in the bold irregular sculpture of long and short ridges, 

 which scarcely form reticulations (best seen on the reverse of fig. 30). iWe can find 

 nothing nearly approaching to our fossil, and as the form is very striking we have 

 given it a name. 



PRUNUS MAXIMOVICZII Ruprecht. 

 PL IX, figs. 32-34. 

 Good specimens of endocarps belonging to this living species of Japan and 

 Manchuria have been found at Tegelen, and were described and figured by us (loc. cit 

 1910, figs. 17, 18). We have now a few poorly preserved endocarps, evidently belong* 

 ing to the same species, from Brunssum and Reuver. The best of them are figured; 

 but the specimens do not lend themselves to further description.
