which was carefully searched for fossils in order to discover whether 

 any evidence existed of a palaeontological break between the two 

 series. The species Thianfeldia sphenopteroides, sp. nov., Cala Eiver, 

 TcEYiioptens Carruthersi, Indwe E,., and Fteropliyllum sp., cf. Pt. 

 Tietzii, Kraai-Eiver Bridge, were obtained from this transition-zone 

 within 30 or 40 feet of the line taken as the base of the Molteno 

 Eeds. It is noteworthy that two of these are common to the 

 Molteno and to the Burghersdorp Beds.

Group EQUISETALES. 



Genus Schizonefra. 



Fossils referred to this genus have been collected from three 

 localities : the Molteno Beds, 1 mile from Dordrecht ; Basutoland ; 

 and Burghersdorp. 



ScHizoNEURA Carrerei, Zcill. (PL II, fig. 1.) 



The Dordrecht specimen consists of portions of slender branches 

 bearing numerous, long, filiform leaves ; the axis is characterized 

 by narrow and slightly -prominent ribs and indistinctly-marked 

 nodal regions (PI. II, fig. 1). There is no doubt as to the identity 

 of the specimen represented in the figure with the type previously
