Mr Etheridge says the individuals of the genus Spirifera 

 were few in number, while Orthis, Chonetes^ and Atrypa were 

 abundant. This is the reverse of what we find among the 

 specimens brought home by Mr Bruce, where the Spiriferce 

 are the most abundant fossils. 



Mr Etheridge recognised definitely three of the species 

 described by Morris and Sharpe, namely, Orthis Sulivaniy 

 Atrypa palmata, and Spirifera antarctica\ but there were 

 four other forms which he referred with doubt to Chonetes 

 falklandica (?), Orthis tenuis (?), 0. concinna (?) and Spirifera 

 Orhignii (?). 



These fossils, as we have seen, were thought by Sir 

 Wyville Thomson to indicate a horizon near the base of the 

 Devonian. 



The " Challenger " fossils were obtained from Port Louis, 

 and were for the most part in a fine liver-coloured, mica- 

 ceous sandstone; but there were also pieces of buff-coloured 

 sandstone, apparently quite a different deposit, containing 

 fragments of Trilobites. 



A further account of the Brachiopoda from the Bokkeveld 

 beds. South Africa, was published by Mr F. K. C. Keed in 

 1893.^ In this paper twenty-eight forms are recognised 

 and described, some six or seven being identical with 

 species recorded by Morris and Sharpe from the Falkland 

 Islands. Mr Eeed thinks these Bokkeveld Brachiopods show 

 an undoubted Devonian facies, but he hesitates to assign 

 them to any particular part of that formation. 



Quite recently Mr Ivor Thomas ^ has described a series of 

 fossils from strata regarded as of Devonian age, which were 

 collected by Professor Bodenbender at Cordoba, Argentina. 

 Among the forty-one forms described by Mr Ivor Thomas 

 there are six Brachiopods which he refers to species described 

 by Morris and Sharpe as Falkland Island, fossils; two of 

 these, and perhaps the most distinctive, Spirifera antarctica 

 and Leptoccelia flahellites, being among the fossils which form 

 the subject of the present communication.
