Diagnosis
ReferenceDiagnosis
A. Williams et al. 1996Brachiopods with calcitic, laminar (tabular) inarticulated shells; valves developed discretely without mantle reversal; larvae lecithotrophic without shell; posterior body wall complete, pedicle not developed, ventral valve attached by larval epithelium; muscle system with a single pair of internal obliques and with paired outside lateral muscles attached anteriorly to the body wall; alimentary tract more or less axial with anus; lophophore initially with median tentacle lost during growth, tentacles in double row in posttrocholophous growth stages only; paired ganglia developed; mantle canal systems without interiomedial vascula terminalia, normally pinnate, containing gonads.
