The fossil leaf, fig. 8, occm-s in a sandy ferruginous stone, 

 which is unfavourable to the preservation of remains of plants. 

 Notwithstanding this cu-cumstance, one is able to observe so 

 many characteristics that at least the approach to a correct, 

 definition is possible. It is quite certain that the texture 

 must be accepted as having been firm and leathery. The 

 impression which the fossil has left on the stone denotes 

 this, as it is developed remarkably unequall}-. If the con- 

 tour is completed, we have a broad oval shape. On the 

 narrower side one perceives a few broad, short, rounded-off 

 lobes. The broader side is mutilated, and consequently the 

 edge of it is only visible at the base. However, to judge 

 from the perfect part of this side, we cannot infer a much 

 greater development of the lobes. The nervation is incom- 

 plete, running in rays with three basal nerves, the middle 

 one of which is rather pronounced, and winds to the starting- 

 point of the secondary nerves. One of the side basal 

 nerves is longer and more pronounced ; it starts just above 

 the base, and sends off at the outer side a few secondary 

 nerves. The shorter one on the other side is not as pro- 

 nounced as the middle secondary nerves ; it is somewhat 

 'liverging, bent outwards, and undi\'ided. The secondary 

 nerves, which are not numerous, start with a somewhat 

 diverging curve ; they continue straight, and run to the ends 

 of the lobes. Tertiary nerves and reticulation are not pre- 

 served. I rank this fossil leaf with the genera Cissites and 

 A 7npelophyllum.
