(1929), WILLMOTT and PESTER (1961) and GUPTA and WA LIA (1971). More recently JONES (1986) rightly pointed out that G. aegyptiacus has no true cirrus pouch. Namely, the true cirrus pouch is a more or less developed sac surrounded with muscle fibres. It incoudes vesicula seminalis interna and pars prostatica with prostate cells. In G. aegyptiacus there is a loosely scattered mesh of muscle fibres, surrounding the terminal part of the male duct which, in this respect, is similar to a true cirrus pouch. Inside it, however, there are the coiled pars musculosa and the dilated chamber, in this respect it differs from a true cirrus pouch. As the cirrus pouch is regarded to be a pleisomorphic state contrary to the apomorphic pars musculosa, therefore it is assigned to this group of terminal genitalium. Types of terminal genitalium with hermaphroditic pouch This group comprises three already known types (Bicaudata Sey et Graber, 1979; Balanorchis Eduardo, 1982; Hawkesius Sey, 1985) and a new one described below. 1. Epuluensis type (Fig. 22) The terminal genitalium enormous, genital papilla present, stout in appearance. Circular muscle units absent. Metraterm and pars prostatica enclosed in hermaphroditic pouch. Radial muscle units forming coarse bands. True genital atrium absent but in strongly retracted position a shallow atrium may be formed between genital papilla and the body wall. (Valid for Choerocotyle epuluensis.) Types of terminal genitalium without cirrus pouch, hermaphroditic pouch and with tegumental papillae This group consists of 12 already known types (Cruciformis Sey, 1983; Elongatus Sey, 1983; Endopapillatus Sey, 1983; Gregarius Sey, 1983; Homalogaster Sey, 1984; Noci Sey, 1984; Papillogenitalis Eduardo, 1980 (= Parvipapillatus Sey, 1983; Microbothriopapillatus Sey, 1985); Parvipapillatum Eduardo, 1982; Raja Eduardo, 1982; Schoutedeni Sey, 1983; Stephanopharynx Näsmark, 1937; Synethes Sey, 1983) and two new ones described below. 1. Olveria type (Fig. 2 3) Weakly developed terminal genitalium, Genital papilla poorly developed with well-developed sphincter papillae. Genital atrium straight-lined with tegumental papillae. Genital fold thick and broad. Radial muscle fibres strongly developed. (Valid for Olveria spp. ) 2. Pseudodiscus type (Fig. 24) Genital papilla and genital fold present. Genital fold with a moderately developed genital sphincter. Tegumental papillae present around the genital pore and outer surface of the genital fold. Radial muscle fibres well-developed. (Valid for Pseudosiscus collinsi. ) Remark Description of the terminal genitalium of this species was published by JONES (1986) but the type was not designated. Types of terminal genitalia without cirrus pouch, hermaphroditic pouch and tegumental papillae This group embraces 29 already known types (Bothriophoron Näsmark, 1937; Bubalis Sey, 1983; Buxifrons Näsmark, 1937; Calicophoron Näsmark, 1937; Clavula Näsmark, 1937; Cotylophoron Näsmark, 1937; Dawesi Eduardo, 1982; Deschiensi Sey, 1984; Duplicisphinctris
