In all the above characters, except the aril, this seed agrees with Turraea; it comes 

 nearest to T. villosa Benn., of Java, the testa of which agrees precisely with our fossil. 



Having only one crushed seed, and taking into consideration the difference of the 

 aril, we do not like to attribute it with certainty to this genus, though the affinity would 

 seem to be very close. Turraea is recorded from Hainan, Travancore, the Phillipines, 

 Malaya, Australia, and Tropical Africa. 



EUPHORBIACEAE. 



EUPHORBIA Sp. 

 PI. X, fig. 17. 



Seed anatropous oval inflated but flattened by pressure; caruncle and raphe 

 large and conspicuous, surface of testa showing small irregularly hexagonal cells. 



Length 2.4 mm., breadth 1.75 mm. Brunssum. 



The size, shape, and general character of this seed, with its large caruncle, seem 

 to place it without doubt in the genus Euphorbia; but the unique specimen is not in a 

 sufficiently good state of preservation for us to carry the identification further. 



EMPETRACEAE. 



COREMA INTERMEDIA Reid. 



In 1908 we figured and described, as probably belonging to an unknown species 

 of Viburnum, some small endocarps from the Cromerian at Pakefield.* Afterwards two 

 endocarps belonging to the same plant were found at Tegelen {pp. cit. 1910, p. 197, figs. 

 30, 31). A further study of the anatomy of the Cromerian specimens has proved that 

 we were mistaken in this ascription, and that the fossil endocarps belong to the genus 

 Corema. Corema is a small genus of heath*like plants, one of which inhabits Spain, 

 Portugal, and the Azores, the other is confined to the Atlantic part of the United States. 

 Our fossil is a new species of the genus, closely allied to the living Portugese Corema 

 alba, and recently has been described by us as C. intermedia, f 



CORIARIACEAE? 



PL X, fig. 18. 



Coccus compressed towards the ventral margin; pericarp crustaceous thin, not 

 keeled; seed somewhat compressed laterally, coarsely and irregularly striate. 



Length 3.7 mm., breadth 2.0 mm. Swalmen. 



In structure this fruit is very near Coriaria. It differs, however, from all living
