The ranges of the American forms are taken from Schuchert’s list (18). 
The foregoing list shows the strong and close affinities of the 
Bokkeveld brachiopods to those of the Devonian of North America, 
and it is remarkable that, according to Katzer (17, p. 199), in the 
ease of the Brazilian members of the same group from the Maecuru 
Sandstone, there is a mixture of upper Lower Devonian and Middle 
Devonian forms, the Lower Devonian predominating; but in South 
Africa the facies is more that of the Middle. 
Haug (11) has recorded several brachiopods from the Devonian beds 
of Tassili in the Sahara which suggest the presence of the Bokkeveld 
fauna, or at any rate of elements of it. The occurrence of Sprrifer cf. 
Rousseawi has been mentioned above. ‘The form called by Haug 
Stropheodonta oriskania, Clarke, and compared with Sharpe’s Chonetes ? 
sp. (14, p. 209, pl. xvi, fig. 14) from South Africa appears to me to 
resemble more closely my Stroph.ctf.coneinna( Morr. & Sh.). The specimen 
figured as Chonetes sp. by Haug may be compared with my Ch. aff. setiger. 
The important species Leptocelia flabellites is definitely identified by 
Haug from Tassili. Schwarz (2) doubts the accuracy of Haug’s 
determinations, but apparently has only the figures by which to judge.
