placed almost on top of each other can sometimes be seek. As the segments mature, the positions of the reproductive organs become arranged, yet the external segmentation frequently remains indistinct and thus the proglottides appear to contain two reproductory systems each. Male reprodutive system: Testes arranged in two rows, 50-60 per segment, separated from the female reproductive glands, in the two lateral fields' of the medullary parenchyma: dimensions 0.025-0.030x0.040-0.050 mm. Cirrus pouch piriform, 0.100-0.150x xO.

070-0.090 mm. Cirrus 0.030-0.035x0.045x0.050 mm. Vas deferens loops within the cirrus pouch. Genital atrium situated in median line and at mid-height of dorsal surface of segment. Ojl mm Pig. 1 Bothriocephalus claviceps: hermaphrodite segments Female reproductive system: Ovary is transversely elongated and compact body, 0.050-0.090x0.450-0.750 mm, situated in the medullary parenchyma, ventrally and adjacent to posterior margin of segment. Vagina terminates behind cirrus pouch at the genital atrium,and runs decurrent along midline of the proglottides towards the ovary. Shell gland measuring 0.040-0.060 x 0.100-
