dc.description.abstract"This is the final part of a study of Permian gastropods from the Misellina claudiae zone from the H. S. Lee Mine No. 8, near Kampar, Perak, Malaysia. The fauna constitutes one of the richest and most diverse known in the Permian-91 species of 52 genera. Included in this portion of the study are analyses of species of the murchisoniids, loxonematids, cerithiids, subulitids, nerineids, pyramidellids, and trochids. This study now provides the best documented Permian gastropod fauna of the Eastern Hemisphere. There are 33 new species of a total of 41 and 4 new genera described herein. The genera belong to the Murchisoniidae, Loxonematacea (incertae sedis), Procerithiidae, and the Nerineidae; the latter two families are important Mesozoic groups reported for the first time in the Paleozoic. The presence of these and other dominant post-Triassic families and the presence of Paleozoic groups in the Triassic serve as additional evidence that a catastrophic event did not affect gastropods at the end of the Permian as it might have in nonmolluscan groups. Of interest is the recognition of a number of species which have very similar morphologies to species from the North American Pennsylvanian, particularly among Retispira, Naticopsis, Trachidomia, Worthenia, Orthonema, and Pseudozygopleura. The presence of an unusually large number of siphonate species (18) in the fauna may indicate the beginning of the exploitation of infauna habitats, perhaps in response to the origin of predation"--P.
