Fauna and Stratigraphy of the Stormberg Series. 455 



Their size, however', is comparable with that of similar bones of 

 Plateotsfiurtix or one of the larger genera of South African Theropoda. 



Southern Rhodesia. 



Molyneux (Quart, Journ. Geol. Soc. 1903, LIX, p. 279) gave the 

 first provisional classification of the Upper Karroo rocks of Southern 

 Rhodesia. Ue suggested the following: 



"Thaba 'Sinduna Series 200 ft. Sandstones and volcanic rocks of 



Thaba 'Sinduna and Shiloh. 



Forest Sandstones . . 1000 ft. Fine sandstones of the forest- 

 country, with sandy clay. Tra- 

 vertine on the surface. Bubi, 

 Gwampa and Sikonyanla basalts. 

 Conglomerate basement near the 

 Djombi River. 



Ksrarpment Grits. . . 400 ft. Coarse red sandstones, with sub- 

 angular pebbles, as seen in the 

 great escarpment which stret- 

 ches from the Mafungabusi Moun- 

 tains to near \Vankie." 



Macgregor' (in lilt.) says thai the beds classed here as Forest 

 Sandstone are largely Kalahari, and therefore of more recent age 

 I ban the Storrnberg. 



In an account of the geology of the region round AVankie, Light- 

 loot (1914) found 100 feet of Forest Sandstones whose top was 

 not seen - - lying on 300 ft. of the Escarpment Grits. The "Forest 

 Sandstone" of this area is said by Macgregor to be equal to his 

 Nyamandhlovu Sandstone. Lightfoot conjectured a break at the base 

 of his so-called Forest Sandstone and, if Macgregor be correct, this 

 break would probably correspond in time to the formation of the 

 Forest Sandstone of the Bulawayo area. 



Macgregor (1916) described the Forest Sandstone of the typical 

 area North of Bulawayo. He divides the sediments into four groups; 



4. Nyamandhlovu sandstones intercalated in basalts. 



3. White sandstone. 



2. Red marls. 



1. Basal beds, resting on old schists etc. 



Maufe (1919) described briefly the Upper Karroo Rocks of the 

 Amanxele Hills in the Bembesi basin north of Bulawavo. There
