South African Palaeozoic Fossils. 

 By E. H. L. SCHWARZ, A.R.C.S., F.G.S. 



In In-inging together the fossils contained in the Albany 

 Museum to foi-m a stratigraphical series for display, I found a great 

 number which could not be referred to known species; as thej^ were 

 undoubtedly new, it was decided to publish them. In the present 

 instalment I figure and describe the fossils of the Bokkeveld and 

 Witteberg Series, a gi'oup of forms in which I have been long 

 interested : most of the new species described by Messrs. 

 Reed and Lake wei-e collected by myself. My first work on the 

 Geological Survey of the Cape Colony was to try and find definite 

 zones in the rock strata in the Western Province, and naturally 

 I sought for the life forms in them to guide me. The result was 

 published in abstract in the Annual Report of the Geological 

 Commission for LSOG, and a full account in the same report for 

 1905. The original account, however, has never been ])ul)lished. 

 As far as the zones in the Bokkeveld and Witteberg beds were 

 concerned, there was nothing definitely decided by my work, 

 although the sequence of the larger rock groups was firmly 

 established ; three years later, therefore, I again made a determined 

 effort to recognise zonal fossils, and searched for Bokkeveld fossils in 

 Ceres and the Gamka Poort in Prince Albert. In the latter i)lace 1 

 was able to collect a large number of species, and to measure each 

 successive bed, one by one; yet I again failed to establish any zonal 

 arrangement of i'orms. One is tempted to describe life pi-ovinces 

 within the beds : noting that the IIoiiialoyiot/Ks predominates in 

 the western and northern outcrops of the Bokkeveld series, the
