{J\HE conspicuous relations of the brachiopod fauna of these beds to 
that of the Lower Devonian in South America have frequently 
‘been pointed out, and may be summarised as follows :— 
(1) In the Falkland Islands the following South African species 
are found (12) :— 
Chonetes falklandicus. Spirifer antarcticus. 
Orthothetes Sulivan. Cryptonella Baini. 
Stropheodonta coneimna. Orbiculoidea Baunri. 
Leptocalia flabellites.

allied species occur :—

It is noteworthy that no members of the genera Rensseleria or 
Piychospira have so far been recorded from South America. 
Ulrich (16) was the first to remark upon the affinities of the South 
African brachiopods of the Bokkeveld Beds to those of the Hamilton 
Group in North America, and especially referred to Leptoceha flabellites 
and Vitulina pustulosa. The following allied or identical species have 
so far been noticed as occurring in the North American Devonian :— 
SourH AFRICA. Nortu AMERICA.
