Palwozoic Fossils. 361 



Oudtshoorn and Rivei-sdale, but the specimens are too poor for 

 description*!. No specimens have been recorded trom the Falk- 

 land Islands, and the South American corals belong toother genera, 

 e. g., Stoiupura ; in North America, associated with many fossils 

 identical with our Bokkeveld ones, there have been described a 

 large number of forms, such as Zaphrentis siin/jlex, Z, gigantea^ 

 Z. ungula. Z. dalei and Z. stokes'. Until comparison with the 

 American forms is possible it is best to keep the South African 

 species separate. * 



In the Carboniferous rocks in North Africa there are also a 

 number of Zaphrentis. From Tidikelt in Algeria, for instance, 

 among other forms, there occur Spii'ifer, Leptaena, Pleuroto- 

 niaria, Orthoceias, Zap/crentis and FenesteUa'^ . The grouping of 

 genera reminds one of that in the Bokkeveld beds, and the occur- 

 rence of Fenestella with Zaplirentis suggests the same conditions 

 of deposition.

CONULARIA. 



This genus was represented in the specimens from the Ceder- 

 bergen, collected by Dr. Smith and submitted by Sir John Herschel 

 to Sir Roderick Murchison^. The last mentioned identified the 

 species with G. quad ri sulcata from the coal measures of Coalbrook 

 Dale*, and Sharpe likewise compared some of the specimens in the 

 Bain collection with this same species, but the state of preservation 

 was too bad to admit of a proper identification. Sharpe's G.
