7?iedia Hr., bnt tlie veins are much more crowded. Besides, 

 there are many other oblong pinnae (figs. 3, 5), smaller in size 

 and with 22-25 veins. One (fig. 4) is characterized by its rounded 

 apex and gently tapering basal portion and only 20 veins, the 

 breadth of the pinna being about 1 cm. Therefore it may better 

 be compared with P. pulchellus Hr.^^

The existence of coniferous plants in the deposit of Naktong 

 is shown by isolated linear leaves much like those of Fîmes Nor- 

 denskjoldi and of its allied species described from the Jurassic 

 deposits of Spitzbergen, Siberia, China, Japan etc. They are 

 found uniformly scattered in the bed, though not numerically 

 abundant. One can distinguish two types by their larger or 

 smaller leaves. The larger leaves (fig. 9) usually attain 3 mm. 

 in breadth and more than 4 cm. in length, with a midrib and 

 numerous fine longitudinal striae on either side of it, thus being 

 quite similar to Finus Nordenshjoldi Hr.^^ in every respect.
