Museum), is represented in pi. v., fig. 5 ; the original figure shows 

 only a single pinna. 



If the specimen had not been named by Tate, I should have 

 probably not ventured to record it under a specific name. The 

 imperfect Hnear pinnae shown in fig. 5 are, no doubt, segments of a 

 pinnate cycadean frond similar to Zamites hiicliianus (Ett.) ; it is by 

 no means unlikely that the specimen named by Tate Palaozamia 

 rubidgei, may represent the apical portion of a frond of which the 

 fragments referred by him to Pakeozamia africaua, are the longer 

 and more spreading segments of the lower or median region.

An imperfect specimen from the Sunday Kiver, Geelhoutboom, 

 showing portions of five parallel pinnae, the longest of which reaches 

 a length of 13-5 cm., with a breadth at the lower end of 1 cm., 

 tapering gradually towards a narrow acuminate tip. The veins are 

 represented as prominent ribs. The dotted outline in the figure 

 indicates that a portion of the rock is not represented.

The type-specimen of Tate (Museum of the Geological Society, 

 No. 11,109) is refigured on pi. v., fig. 3. I have not met with any 

 examples of this type in the collection recently received from Cape 

 Colony. It is possible that the discovery of more perfect material 

 may render it advisable to substitute for Zamites some other generic 

 name, but for the present I prefer to make use of that designation. 

 The fragment may be compared with such a fossil found as Zamites 

 buchianus (Ett.) of Wealden age,''' as described from England, 

 Germany, Japan, and elsewhere. The veins are parallel and, so far
