Some Wenlockian fenestrate Bryozoa
£1.00
Fenestella rigidula M'Coy 1850 and F. lineata Shrubsole 1880 are considered to be conspecific. Their zooecial chambers are shown to contain structures comparable with the diaphragms of the Trepostomata, and a new genus, Archaeofewstella, is erected to contain them. One new species and two new subspecies are described: Archaeofenestella rigidula polynodosa, Fenestella pseudosubantiqua, and F. pseudosubantiqua catrionae. Elias's (1956) suggestion of the presence, in the English Wenlockian, of d'Orbigny's genus Reteporina from the Devonian is confirmed. A new genus, Neoreteporina, is proposed for certain Carboniferous species described by Nekhoro-shev. Finally the polyphyletic nature of the genus Fenestella is suggested.
