 the Staffordshire Coalfield.

It is very distinct in general form from Fouquea cambrensis, 

 figured and described by Mr. H. A. Allen, F.G.S., from the Coal- 

 measures of South Wales, but it certainly belongs to the same 

 group as Litliomantis and to the family Pla.typterida. 



V. — On the Permian and Tkiassic Faunas of South Africa. 

 By Professor R. Broom, M.D., D.Sc, Victoria College, Stellenboscli. 



UNTIL recently very little attempt has been made to classify 

 the reptilian fossils of the Karroo Beds according to their 

 geological horizons. Seeley recognised certain zones — (1) the 

 zone of Mesosaurs, (2) the zone of Pareiasaurs, (3) the zone of 

 Dicynodonts, (4) the zone of specialised Theriodonts, and (5) the 

 zone of Zanclodonts. While the order of these zones is correctly 

 given they do not cover the whole period, and the third zone is an 

 unnatural one. 



As the result of the work of the last few years, it is now possible 

 to subdivide the Karroo Beds with some degree of accuracy into 

 a number of fairly well-marked distinct faunas. At the recent 

 meeting of the British Association a paper was read, which will 

 appear elsewhere, giving the details of recent work. As, however, 

 much interest is at present being taken in the Triassic faunas of both 

 Europe and America, a summary of the conclusions come to may be 

 of use to workers in the northern hemisphere. 



The most recent rocks of the Karroo Series are the Upper 

 Stormberg Beds. These contain remains of the Dinosaurs Masso- 

 spondylus, Euskelesaurus, and Hortidotarsus, and of the small crocodile 

 Notochampsa. As NotocJiampsa is a true crocodile, we may safely 

 refer the beds to Lower Jurassic, more especially as the Lower 

 Stormberg or Molteno Beds immediately below have been referred 

 by Seward from the evidence of the plant remains to the Khastic. 



Below the Molteno Beds we come to the Cynognathus Beds, 

 corresponding to the ' specialised Theriodont ' zone of Seeley. In
