The two seeds figured may be the 3*keeled seeds belonging to one of the Hama= 

 melidaceae allied to Liquidambar ; but no fruits belonging to any of these genera have 

 yet been found at Brunssum. 



EUCOMMIACEAE? 



At the present day this is a monotypic family represented by a single tree, 

 Eucommia ulmoides (Plate XVII, fig. 33) in the temperate belt of Western China. We 

 cannot definitely place any of our fossil fruits in this family ; but here we must draw 

 attention to the curious samara figured in Plate XVII, figs. 34, 35, and described on 

 p. 139. If this samara does not belong to the Eucommiaceae we are quite unable to suggest 

 where it should be placed. Tegelen, Brunssum. 



ROSACEAE. 



The Rosaceae were evidently abundant, especially the genus Prunus, which has 

 9 species, each represented by very few specimens. The rarity or absence of Potentilla 

 is noticeable, for this genus is not uncommon at Tegelen ; Rosa has not been observed. 

 Thus far we have been unable to identify among our fossils any of the nonsEuropean 

 genera so conspicuous in China ; though one of the Rubi belongs to a section of the 

 genus now purely Asiatic. This family is still very imperfectly known from the Reuverian. 

 This is due to the circumstance that the hard endocarps as a rule do not float ; therefore 

 they are but sparingly transported by the river. We find only a few specimens belonging 

 to each species, and these probably were transported and scattered by birds. 



COTON EASTER ACUTICARPA Sp. nov. 

 PI. IX, figs. 1, 2. 



Carpella quinque, parva, angusta, margine ventrali recta, dorsali semicir* 

 cularia; stylus marginem ventralem terminans, ultra carpellum extensus. 



Carpels 5, small narrow, ventral margin straight, dorsal margin semicircular; 

 style terminating the ventral margin and projecting beyond the carpel; smooth nude 

 area occupying about l /i of the dorsal surface and separated by a very oblique bound* 

 ary from the rugose attached area. 



Length 3.0 mm., breadth 1.8 mm. Reuver, Swalmen, Brunssum. 



Allied to C. pyracantha (fig. 3, 4) but distinguished by the more elongated fruit 

 narrower carpel semicircular not gibbous, and styles terminal not sunk. 



PIRUS MALUS Linn. var. 

 PI. IX, fig. 5. 

 A well-preserved seed and a fragment of another are quite indistinguishable 

 from the recent P. malus (fig. 6), except that they are somewhat rougher. 



Length 7.3 mm., breadth 4.0 mm. Brunssum.
