358 R. B. Newton — Fossils from Nubian Sandstone, Egypt. 



Seward,' exhibited strong resemblances to the Carboniferous Pecopteris 

 and the "Wealden Weichselia. The results of a further study of this 

 plant enabled Professor Seward to recognize it as part of a frond 

 of Weichselia, and although, with considerable hesitation, he was 

 inclined to regard it as of Wealden age, he was aware that no great 

 weight should be attached to such an opinion. The same expert 

 described another fern (in the same paper) from the Nubian Sandstone, 

 found by Mr. H. T. Ferrar east of Edfu, between Wadi Dum and 

 Wadi Abbad, as Clathropteris Egyptiaca, n.sp. In connexion with 

 this it is stated that "such evidence as the fragment affords is 

 primarily in favour of Rhsetic or Lower Jurassic age ", an opinion, 

 however, which is mentioned as being contrary to that of Dr. Hume, 

 who regards the sandstone in which the specimen was found as 

 Upper Cretaceous. 



It will be convenient now to tabulate the fossils from the Nubian 

 Sandstone Series of Southern Egypt and Nubia, which have been 

 briefly referred to in the foregoing review of published notices on 

 this subject.
