A single specimen of a fragment of an equisetoid stem 25 mm. 

 broad, and 170 mm. long, of which the lower 90 mm. is a cast. 

 There are two nodes, one near the upper end of the fragment, 

 and the other about 70 min. from its lower end, the internode 

 between being nearly 90 mm. in length. The surface of tlie stem 

 shows longitudinal I'idges and grooves, the former about half a 

 millimeter broad and the latter much narrowed. The surface of 

 the ridges is finely striated in the longitudinal direction. 



I believe this j^lant is to be identified with the well known 

 species widely distributed in the Rhaïtic of Europe, and accord- 

 ing to Raciborski, also occuring in the Jurassic of Poland.

Tlic specimen which I designate by the above name is a 

 k^af consisting; of several lobes which ao-ain divide into two lony; 



o or? 



narrow ones. These are more or less parallel-sided, bluntly 

 pointed, o-ü mm. broad, pierced with )] or 4 longitudinal veins, 

 between which several interstial ones are also observable. The 

 lower ])art of the leaf is not preserved, but that it is a fan- 

 slia})e(l one is (juite evident. I believe it is to be identilied with 

 the species abf^ve named, tlescribed long ago from Scarborough 

 in England.
