A delicate, oblong, elliptic leaflet, which has a short petiole 

 aud which reminds one in its characteristics most of Dalbenjia 

 bclla, Heer, of the Tertiary flora of Switzerland. Our fossil is 

 distinguished from the species named only by the much shorter 

 petiole, the less narrow base, and the more oblong form.

Corresponds so much with Casi^ia pJiaseolitcs, Ung., that 

 one might be betrayed into accepting the occurrence of this 

 species in the Tertiary flora of New Zealand. The only 

 difl'erences ^vhich seem to exist between this part of a leaflet 

 and the species named are the following : The texture of the 

 New Zealand species may be accepted to have been somewhat 

 firmer, and the diverging-angles are more acute. However, 

 these difl'erences are too insignificant and too little confirmed 

 to uphold the division of these fossils if no difference should 

 appear in the characteristics of the tertiary nerves and of the 

 reticulation. The proof of this must be a task for future re- 

 searches. The fossil leaves here shown lie on one stone 

 beside each other, aud might be parts of leaflets of the sRine 

 leaf.

Small narrow parts of leaflets of distinctly delicate texture, 

 provided with a faint primary nerve, and with very ascending 

 secondary nerves, which approacli each other. They may be 

 compared very well with part-leaflets of Cassia meinnonia, of 

 which latter well-preserved remains from Parschlug are before 

 me ; but our fossil is distinguished from these by the direction 

 and the larger number of the secondary nerves.
