and 14 of his map (1856), or the ' Ecca,' 'Koonap,' and part of the 'Beaufort' 

 Beds of Jones (1807). The series No. 7, horizontal and unconformable on the 

 Ecca Beds at the Oamdeboo and elsewhere, retains the name oi Karoo Sandstones ; 

 hud after a width of about 40 miles is conformably surmounted by a set of some- 

 what similar Beds (8) in the Stormber<^ ; and thus No. 7 should be regarded as the 

 Lower, and No, 8 the Upper Karoo Sandstonefi. The latter end off northwards in 

 the Draakensberg, Natal, Orange-Free-State, the Transvaal, and Zululand, with the 

 still horizontal Cave Sandstone and associated beds. The Loiver Karoo Sandstones 

 probahly thin away northwards beneath the others. Below the Karoo SandstoneSf 

 aud dying out southwards near the Oamdeboo (Prof. Green), are the Shales (7*), 

 which constitute the country around Kimlwrley, described as the 'Olive Shales of 

 the Karoo Formation,' by G. W. Stow. These die out northward against the old 

 rocks of ( iriqualand-West and the Transvaal. They contain Glacial ('onglomeratea 

 iu thfir lowest (earliest) beds, in Griqualand-West, just as the Ecca series has ita 

 <rreat Glacial Conglomerate (the Dwyka Conylomerate in No. 6) in its lowest 

 portion. As the Stormhcrti Beds (8) lie upon the Olive or Kimberley Shahs (7*) in 

 the Orange-Free-State, the Loicer Karoo Sandstones (7) must die out northv/ards. 

 The Kimherleif Shales contain some Iteptilian bones and plant remains, and some coal 

 on the Vaal ; the Karoo Sandstones are rich with Dicyuodont and other Keptilian 

 bone?, and have some Fish remains ; and their upper portion {Stornd>erg) contains 

 Ferns and I ly eadeous leaves, and some seams of coal. A fossil mammal also has been 

 found in this «!ries. Throughout its range the Karoo Series is traversed with 

 igneous dykes. 



Limestones and sandstones (9) with fossils of nearly pure Jurassic, but with 

 some of ( 'retaeeous type, occur unconformably in the Eastern Province, Their 

 fossil Flora is like that of the Stormherg Beds. Cretaceous strata (10) are known 

 on the Natal coast; and Tertiary and post-Tertiary deposits (11) form several 

 patches on the East, South, and West coasts.
