| Abstract |
The rhynchonellid brachiopod genus Cretirhynchia PETTITT, 1950 was in need of revision. Representatives of this genus together with the original material studied by PETTITT in 1950 and 1954 were reviewed. Transverse serial sections were made and the internal structures observed in this study allow us to remove some species from the genus Cretirhynchia and to split the genus into four subgenera. A new species and a new subspecies of Cretirhynchia are described here. In addition a new genus, related to the genus Cyclothyris M'COY, 1844 has been erected. |
