Extract

The genus Camarophoria was established by King in 1846 for certain Permian brachiopods bearing internal structures similar to those of the Pentamerids. The essential features were the presence in the ventral valve of a spondylium (“an arch-shaped process”) supported by a median septum (“medio-longitudinal plate”). “The arch-shaped process and its supporting or suspending plate correspond in every respect except in degree with the apophysary system belonging to the large valve of Pentamerus.” In the dorsal valve there is developed a high median septum supporting a well-developed spondylium (“spatula-shaped process”).
