Abstract
Brachiopod pedicles are variable structures, immobile and rigid in some genera, muscular and flexible in others. Different pedicle types are related to differences in the disposition of pedicle muscles and in the form of associated shell structures. The pedicles and musculature of eleven species from Australia and New Zealand are described — Notosaria nigricans (Rhynchonellacea), Cancellothyris hedleyi (Cancellothyridacea), Liothyrella neozelanica (Terebratulacea), Frenulina sanguinolenta (Laqueidae, Terebratellacea), Campages furcifera (Dallinidae, Terebratellacea), Megerlina lamarckiana, Terebratella sanguinea, Terebratella inconspicua, Magadina cumingi, Magelian flavescens, Neothyris lenticularis (Terebratellidae, Terebratellacea).
