Extract

It is unusual to discover specimens of Palaeozoic Brachiopoda which clearly display the characters of the delthyrium; in particular, very little is known concerning these features in Carboniferous Protremata. The writer has therefore been fortunate in obtaining well-preserved examples of Chonetes, in which the ventral pseudodeltidium and the dorsal cardinal process are exhibited in detail. It has also been found possible to determine the internal features of these structures by means of serial sections.
