Observations on Zealandian Triassic and Jurassic Brachiopoda.

This paper includes a series of new records, nomenclatural changes and changes in stratigraphic and geographic ranges of Brachiopoda from the Triassic and Jurassic of New Zealand and New Caledonia. Following a suggestion in the Treatise on Invertebrate Paleontology, the Early Jurassic species Vincentirhynchia uitoeensis and Vincentirhynchiapomeyroli are assigned to the genus Prionorhynchia. Specimens of Aparimarhynchia dunrobinensis from the Kaka Point Fold Belt, South Otago are recorded and figured, and the time range of the genus Aparimarhynchia is reviewed. Two species of Norellidae are now recognised, and are tentatively placed in the subfamily Diholkorhynchiinae. Clavigera drotae is reviewed on New Caledonian material in University of Auckland collections. A single related specimen is recorded from Kawhia. The New Zealand material identified by Trechmann (1918) as Spiriferina fragilis is assigned to Punctospirella Dagys, 1974, of which S. fragilis is the type species. The use of Punctospirella cf. fragilis is recommended for the Zealandian material. A newly found spiriferinide from the Late Triassic (Otapirian / Rhaetian) of Marokopa, Kawhia Syncline is identified as Dispiriferina cf. davidsoni. A spiriferinide previously noted as Psioidiella from the Hettangian of New Caledonia is doubtfully identified as Spiriferina arakiwa. New records of Linguithyris ageri, Murihikurhynchia malingi and Herangirhynchia awakinoensis extend the stratigraphic and geographic ranges of these species.
