Papillae anales well developed, symmetrical. Ostium bursae quite normal, strongly chitinized. Bursa copulatrix normal, but lamella antevaginalis absent, the postvaginalis in the form of a chitinous band (Fig. 7, /. p.}. On the other hand, there is a penis, with its ccecum (Fig. 7, c. pn.}, rather well developed and lying inside of the body cavity, but capable of being protruded through a very narrow orifice in the diaphragm. Uncus absent. Rudiments of tegumen in the form of a more strongly chitinized left portion of the 9th tergite (Fig. 8, tgm.}. A well-developed left portion of the subscaphium (Fig. 8, ssph.} lying below the left papilla analis. As to the valvae, they are both present, but deformed, lying within the body cavity and protruding only partially outside (Figs. 8 and 9, v. s. and v. d.}. Lastly, an oviform structure lying freely in the body cavity on the external surface of the right valvoid (Fig. 7, ) may be regarded as a rudiment of the saccus. a a. Si-7. ' FIG. 9.
