There are very few rliynclionelloid species in the Carboniferous and Permian 
faunas which, without evincing any essential difference from Camarotcechia in 
the character of the internal apophyses, possess a strong shell-punctation, not 
merely superficial but extending quite through the thickness of the valves. 
To one of these shells, Terebratula Geinitziana, de Verneuil, King gave the name 
Rhynchopora, in 1856; a Permian species described from Russia, though the 
examples upon which King established its generic characters were obtained 
from the Zechstein of Germany (Ropsen). Dr. Geinitz had identified de 
Verneuil’s species in 1848,* and in 186 If in the German faunas, and Tscher- 
NYSCHEwf has more recently shown that the Russian specimens possess the shell 
punctation, so that there is no reason to doubt the specific identity of the type. 
None of the figures which have been given of this species nor of the R. Nikitini, 
Tschernyschew,§ also from the Permian, nor of the R Youngi, Davidson,|| from 
the Upper Carboniferous limestone of Ayrshire, show the interior characters 
of the shells. From an examination of the only American species which can 
now be referred to Rhynchopora, namely, Rhynehonella pustulosa. White, of the 
Burlington limestone, it appears that the teeth are supported by conspicuous 
vertical lamellae, the septum of the brachial valve well developed and the
