pregravid. Genital pores irregularly alternating in short series (e. g.

... 1, 2,1, 1, 4,1, 1, 2,1, 3,1, 2, 2,1,1, 4,1, 2; or ... 2,1, 2, 2,2,1,1,1,1, 3,1, 2,1,1, 2, 1,1,2,1, 2,2,2, 2, 1); open in anterior 1/5 - 1/4 of lateral proglottis margin. Genital atrium (Fig. 3) consists of two parts: distal part with infundibular orifice and tubular lumen with diameter 32 - 63 (av. 50, n = 10), surrounded by intensively stained cells and muscular fibres; genital papilla not observed, but probably this part protrudes prominently as papilla. Proximal part of atrium forms tube with pipette-like orifice and welldeveloped circular musculature, also surrounded by intensely stained cells; measurements of lumen 91 - 107 x 25 - 32 (av. 98 x 29, n = 8). Ventral osmoregulatory canals 11 - 27 (av. 19, n = 10) wide, with transverse anastomoses. Dorsal osmoregulatory canals 5-11 (av. 9, n = 10) wide. Genital ducts dorsal to longitudinal osmoregulatory canals. Testes 28 - 39 (av. 33, n = 24) in number, situated in median field posteriorly, laterally and dorsally to ovary and vitellarium; reaching anteriorly to level of cirrus-sac, may overlap osmoregulatory canals laterally (Fig. 2B). External vas deferens convoluted near anterior proglottis margin; very wide, resembling seminal vesicle; diameter 27 - 38 (av. 31, n = 8); cellular covering on external vas deferens present as isolated single cells. Cirrus-sac (Figs 3A-C) with thick muscular wall; highly elongate, 528 630 x 58 - 103 (av. 582 x 82, n = 11); situated obliquely and very often reaching aporal osmoregulatory canals. Internal vas deferens in young mature ('male') proglottides enveloped with distinct cellular sleeve; internal vas deferens in well-developed mature proglottides very wide and similar to convoluted seminal vesicle; diameter 28 - 39 (av. 33, n = 7). Ductus ejaculatorius with diameter 2-5 (av. 3.5, n = 8); its distal transformed into specialized structure, apparatus expulsor spermae (Figs 3 B-C). Evaginated cirrus consists of two parts: proximal part conical, at distance of 22 - 28 (av. 25, n = 6) from base with spinose zone 39 - 52 (av. 46, n = 6) long; diameter at base 25 - 30 (av. 27, n = 6), diameter at terminal end of spinose zone 13 -18 (av. 15, n = 6), distal part of cirrus flagellum-like, usually convoluted, with diameter 4.5 - 7.2 (av. 5.6, n = 8). Vitellarium median, lobed. Ovary rosette-shaped, two-winged, aporal wing larger than poral; each wing consists of several long digitiform lobes; in fully-developed ovary, lobes reach almost to longitudinal osmoregulatory canals. Mehlis' gland clearly visible, with diameter 54 - 95 (av. 83, n = 10). Seminal receptacle elliptical, 349 - 420 x 143 -192 (av. 396 x 166, n = 8), situated obliquely between centre of proglottis and cirrus-sac, in some cases overlapping cirrus-sac; sometimes seminal receptacle sigmoid. Vagina (Fig. 3) opens anteriorly to male pore, forms arch which passes dorsally to cirrus-sac; vaginal lumen 129 - 210 x 27 - 54 (av. 171 x 38, n = 10); vagina enveloped by intensely stained layer of glandular cells 32 - 57 (av. 42, n = 8) wide. Vaginal sclerite (Figs 3B-C, 4C-D) situated between vagina and seminal receptacle, dumb-bell shaped; measuring (n = 15): length 61-75 (av. 69), diameter of part directed towards vagina 27 - 36 (av. 31), diameter of part directed towards seminal receptacle 38 - 45 (av. 42), diameter of narrower median part 11-14 (av. 13). Developing uterus (Fig. 2C) lobed, with many internal septae, occupies median field and parts of lateral fields.
