formations. A translation of the latter work appeared in New 

 Zealand in 1801. In 1893 the same author published a 

 preliminary essay on the Cretaceous Flora of Australia, followed 

 by an illustrated paper in 1895 ; and a general account of the 

 Cretac30iis Flora of the Southern hemisphere appeared in ISOfi. 

 Finally in 1896 Johnston described and figured several plants, 

 probably of Upper Cretaceous age, from Tasmania. 



JAPAN. 



Lower Cretaceous plant-impressions from Japan were first 

 described by Yokojama (1889) in his paper on the Jurassic 

 Flora, and additional species were subsequently described and 

 figured by Nathorst (1890) and Yokoyama (1894). He pointed 

 out the very close afiinity of many of them to the Potomac 

 plants of North America. The Japanese Cretaceous formations, 

 however, are notable as being the only deposits of Mesozoic age 

 which have hitherto yielded petrified masses of plants in many 

 respects similar to the well-known Carboniferous " coal-balls," 

 In a paper largely dealing with Tertiary specimens Reiss (1907) 

 described a few fragments of Gymnospermic wood from these 

 nodules ; and the remains of an extensive fl.ora, including the 

 leading plant phyla, have been discovered in them by Stopes 

 and Fujii (1909, 1910), Stopes (1909, 1910), Kershaw (1910), 

 and Suzuki (1910). 



INDIA. 



Feistmantel (1877) described a tree-fern from the Cretaceous 

 of India, but all other records of Cretaceous fossil plants from 

 this region are doubtful. 



CHINA. 



Yokoyama (1906) records from China a few impressions of 

 plants which are probably of Lower Cretaceous ago. 



NOETH AMEEICA. 



Canada. — Much work on the extensive deposits of Cretaceous 

 plants was done by Dawson (1873-1894), who dealt principally 

 with the numerous impressions of dicotyledonous leaves and
