摘要:
Morphological characters used in comasterid taxonomy are reappraised. As a result, form and distribution of pinnule combs are newly promoted as primary characters of generic recognition. Form and arrangement of cirri and division series, as used by A. H. Clark (1931), are rejected as characters important in recognizing taxa higher than species. Five of 12 comasterid genera reported as occurring in Australian waters (H. L. Clark, 1946) are critically examined. Of these genera,ComantheriaA. H. Clark, 1909b is referred to the synonymy ofComanthusA. H. Clark, 1908a,ComanlhoidesA. H. Clark, 1931 is referred to the synonymy ofCenoliaA. H. Clark, 1916b, andComanthinaA. H. Clark, 1909b is maintained. In addition, two new genera are described. These genera are related by the occurence of the first brachial syzygy at 3 + 4 on all arms. Twenty‐six species within the five genera are now recognized in Australian waters. Nine new species are described, and the 17 existing species are rediagnosed and critically reappraised. The revision involves taxa distributed throughout the Indo‐west Pacific region, as far west as S Afr

摘要:
The described fossil testudinids from the Miocene of Africa are reviewed.Geochelone stromerisp. nov. is described from Lower Pliocene (Langebaanweg) and Miocene (Namib) specimens.Kinixys erosa, an extant species, is reported from Songhor Hill.Chersinasp. is reported from Arrisdrift.Impregnochelys pachytectisgen. et sp. nov. is described from Rusinga Island, Kenya, and is unique in having the anterior shell opening orientated ventrally and in having struts on the internal surface of the neurals, but shares withKinixysa unique epiplastron shape, a high number of axillary scutes and unique orientation of the head of the femur.
