VIII. -Bmchiopoda from tJie Bokkeveld Bech. By F. E. C. Eeed, 

 M.A., F.G.S. 



(Plates XX.-XXIII.) 



Introductory Remarks. 



The specimens of BrachiopocTa which are here descrihed are mostly 

 in a poor state of preservation and in the condition of casts or 

 impressions. There is considerable variation in the nature of the 

 rock-matrix which contains them, but in the majority of cases it 

 is of an arenaceous character. Several distinct beds and lithological 

 horizons are I'epresented, but as to any difference in age there is 

 no striking evidence from the Brachiopoda, and the general state- 

 ment that the whole facies is certainly Devonian is alone safe. 



The following is a list of the species represented in the collection 

 W'hich has been submitted to me, and described in detail below : —
