In the introduction to my paper entitled " Mesozoic Plants 

 from Korea 'V^ I made a brief reference to the plant-bearing slate 

 of Mnn-g}'ong,"^ in northern Kyong-syang-do, in which Dr. C. 

 GoTTSCHE once found what seemed to him to resemble Neuropteris 

 fexuosa Sternberg, a species characteristic of the Carboniferous.^^ 

 After the more recent discovery of Jurassic plants in a sandstone- 

 and shale-complex well exposed near Nak-tong, the greater part of 

 the tract, which was formerly regarded by Gottsche as composed 

 of Carboniferous rocks, was proved to be decidedly younger. Never- 

 theless the plant-bed of Mung-yong itself was still considered to be 

 Palaeozoic. I, however, retained the impression that it was of 

 a somewhat younger geological age, and therefore I once expressed 

 this opinion in the foot-note to p. 28 of my ''A Contribution to the 

 Genus Fusulina, with Notes on a Fusulina-h\mQ?>iOY\Q from Korea "^'
