Fig. 60 after Hyman (1945), modified. 



Preserved specimens 20 mm long, eyeless, white. Anterior end truncate, 

 with conspicuous adhesive organ. Marginal rhabdites only slightly 

 larger than those of the general epidermis. Adhesive organ consists of 

 a depression with openings of eosinophilic glands and muscular differ- 

 entiations. Testes dorsal, prepharyngeal. Penis bulb slightly devel- 

 oped, penis papilla rounded, with weak musculature. Sperm ducts unite 

 outside the penis bulb to form a canal, the ejaculatory duct, which 

 after a short sinuous course opens at the center of the penis papilla. 

 Male atrium with very tall epithelium, receiving at its posterior border 

 the long common oviduct. The small common atrium, which connects with 

 the bursal canal, has irregular blind diverticula (important specific 

 characteristic). Bursal canal long, narrow in its anterior section but 

 widening as it approaches the atrium. Known only from a spring in 

 Kansas. Literature: Hyman (1945).
