16. Dilymphosa type (Fig. 44) Moderate or well-developed in size, with moderately developed acetabular wall and poorly developed acetabular cavity. D.e.c. series short, with some units. D.i.c. and v. i. c. series more or less similar in number and size. Exterior longitudinal fibres well-developed. Radial fibres well-developed, forming evenly spaced bands. Oblique well-developed fibres at ventro-lateral side. (Valid for Stunkardia dilymphosa , S. amboinensis , Schizamphistomum erratum.) 17. Choerocotyloides type (Fig. 45) Enormous in size, with well-developed musculature and moderately developed acetabular wall and acetabular cavity. D. e. c. and v. e. c. series consisting of a single row of units, comprising a few, weakly developed units. Ventral part of acetabulum with well-developed oblique fibres. Radial fibres well-developed, forming closely packed coarse bands. D.i.c. and v.i. c. series similar in size and in number. Exterior longitudinal fibres moderately developed. M. e. c. present. (Valid for Choerocotyloides onotragi.) 18. Gemellicotyle-type (Fig. 46) Size enormous, with a central adhäsive organ surrounded by irregular rings of papillae. Acetabular wall well-developed, acetabular cavity shallow. Circular series composed of weakly developed muscle units. D.e.c. and v. e. c. as well as d.i.c. and v. i. c. have different number of units. Exterior longitudinal and radial fibres poorly developed. (Valid for Gemellicotyle wallabicola.) Remark Diagnosis of this type was described by PRUDHOE (19 75) without giving type designation. Types of acetabula of group II This group include 15 already known types (Buxifrons Näsmark, 1937; Calicophoron Näsmark, 1937; Carmyerius Sey, 1983; Cotylophoron Näsmark, 1937; Duplicitestorum Näsmark, 1937; Explanatum Näsmark, 1937; Fischoederius Sey, 1983; Gastrothylax Näsmark, 1937; Gigantocotyle Eduardo, 1982; Nilocotyle Näsmark, 1937; Paramphistomum Nasmark, 1937; Pisum Näsmark, 1937; Streptocoelium Näsmark, 1937; Stephanopharynx Näsmark, 1937; Symmery Näsmark, 1937) and a new one described below. 1. Pertinax type (Fig. 47) Well-developed in size, with papillae on the inner surface of acetabulum; musculature moderately, acetabular wall and cavity well-developed. Circular series consisting of a single group of units. D.e.c. series separated by oblique fibres from the inside. Units of interior series similar in size. M.e.c. poorly developed. Radial fibres strongly developed, fibres closely spaced. (Valid for Macropotrema pertinax. ) Types of acetabula of group III This group embraces six already known types (Brumptia Näsmark, 1937; Gastrodiscus Nasmark, 1937; Hawkesius Sey, 1985; Homalogaster Sey, 1984; Pseudodiscus Näsmark, 1937; Watsonius Näsmark, 1937 (= Gastrodiscoides Sey, 1984).
