List of those species of Ordovician and Silurian chilidiopsoid brachiopods probably
belonging to either Coolinia and Fardenia, but whose published illustrations do not show the
characteristic generic diagnostic features described in the printed paper. In this online
material only references additional to those in the printed text are given.
Several species were originally described as Orthotetes Fischer, 1829 (now within the
Orthotetidae); Schellwienella Thomas, 1910, Schuchertella Girty, 1904, and Streptorhynchus
King, 1850 (all within the Schuchertellidae) or Strophomena Rafinesque in de Blainville,
1824 (in the Strophomenidae). The Devonian to Permian families Orthotetidae and
Schuchertellidae were revised by Williams & Brunton (2000), and the Ordovician and
Silurian Strophomenidae were revised by Cocks & Rong (2000).
Schuchertella subplana var. brevior Foerste, 1923, from un-named beds of uncertain age
(possibly Hirnantian) below the Brassfield Limestone in Centerville, Ohio, U.S.A.
Schuchertella missouriensis var. convexa Savage, 1913, from the Noix Limestone
(Hirnantian), Illinois, revised by Amsden (1974) as Coolinia? convexa, but no
interiors or interareas are known.
Fardenia costatula Cooper and Kindle, 1936, from the Whitehead Formation (Katian) of
Percé, Quebec, Canada.
Schuchertella creditensis Foerste, 1923, from the Whirlpool Sandstone (Rhuddanian) of

Schuchertella curvistriata Savage, 1913, from the Channahon Limestone of Channahon,
Illinois, revised by Amsden (1974) as Coolinia? curvistriata, but no interiors or
interareas are known.
Schuchertella daytonensis Foerste, 1923, from the Brassfield Limestone (probably Aeronian)
of Dayton, Ohio.

Missouri, U.S.A., revised as Coolinia? missouriensis by Amsden (1974), but the
types are lost and no interareas are known.

Island, Ontario, Canada.

(Pridoli), Maryland, U.S.A.
Fardenia subdivisa Bancroft, 1949, from an uncertain locality, but given as Cautley?, which
would indicate Late Katian rocks in the Lake District of England.
Streptorhynchus tenuis Hall, 1863, from the Waldron Formation (Telychian – Sheinwoodian)
of Indiana, revised as Schuchertella by Prouty & Swartz (1923).
