Brachiopoda from tlie Bokkcveld Beds. 191 



Ijolmata from the Falkland Islands in 1846, and ten years later 

 Sharpe recorded it from Cape Colony as Orthis palmata. Salter 

 subsequently, in 1861, termed the same brachiopod from the Devonian

This well-marked species (first recorded from South Afi-ica hy 

 Ulrich, op. cit.) is represented by some pedicle valves (No. 220) from
