The nearest form s nmtis to b ' the Krtzia tvardianu, liartt, 

 from I^razil, which Katzer^ refers to the genus, Gcntronrlla. rieed, 

 /o^'. r//., recognises its centronellid characters, but |)hices it among 

 the Athyridfe under the genus Rhi/ncfio.yjira. It seems best to 

 confine the genus, Gcntronella liillings, to the smooth forms, mostly 

 North American, and to unite the plicated forms, C. s/'/tijj/e.r n.s., 

 G. s/lrrti, Ulrich, G. luargarida, Derby, G-hfrgcroni, Oehlert, and 

 G. gaudryi, Oehlert, from South America, South Africa and France, 

 under the genus Trigeria.

 Verneuil ' in their memoir on the fossils in the Rhenish Provin- 

 ces under tlie names Sji. iiiai/'oj/fc/'ns, Goldfuss, and S/i. s/jrr/Dsiis,
