needle-shaped leaves are arranged in whorls as in our recent Sciadopi- 

 tys. In the Bulletin I followed the above author in the generic deno- 

 mination of our species. But in reverence to Prof. Nathorst of 

 Stockholm who thinks it still unsettled whether the plants described 

 by Heer and Schmalhausen really belong to one and the same species, 

 I resume the older denomination of Heer. Loc. — Shimamura. 



6. Palis sy a Endl. 



Species of this genus are mainly known from the Rhaetic and 

 Lower-Liassic beds of Europe, but also from the Rajmahal, Jabalpur 

 and Kach series in India. 



47. Palissya sp. 

 PI. IX, fig. 11. 



A single specimen of a branch of a coniferous tree belonging to 

 the family of Abietaceae shows linear-lanceolate leaves, 10-11 mm. 

 Ions' and 1^ mm. broad, constricted at base and decurrent to the 

 stem. Each of these leaves is pierced with an indistinct midrib. 



This species is undoubtedly very closely akin to P. jabalpurensis 

 Fcislm. (Flora of the Jabalpur Group, p. 16, VI. IX, fig. 1) from the 

 Oolite of India. It is also not unlike a Palissya figured by Feistman- 

 tel, and described as closely related to P. inclica Feistm. (Jurassic 

 Flora of the Rajmahal Group, PL XLV,fig. 9) from the Liassic series 

 of the same country. To our great regret the Japanese specimen has 

 the apex of all the leaves broken, and so it does not allow us to 

 institute a stricter comparison with the above fossils.
