Fig. 64. View from dorsal side (after Hyman, 1937b). 



Up to 15 mm long. Anterior end truncate, with a well-developed, protru- 

 sible adhesive organ in the middle of the frontal margin, and rounded 

 lateral edges. No distinct narrowing or neck behind the head. Pig- 

 mentless and blind. Lateral margins with large rhabdites. Testes 

 dorsal, prepharyngeal . Penis with muscular bulb and well-developed, 

 cylindrical or conical papilla. The sperm ducts enter the bulb and 

 unite to a common canal representing the ejaculatory duct. There is no 

 histologically distinct seminal vesicle, but the duct may show a small 

 widening in its course. Common ovovitelline duct opening into the pos- 

 terior part of the male atrium. Bursal duct displaced to one side of 

 the midline, seems to be widened in its terminal section. Caves in 

 Kentucky. Principal literature: Hyman (1937b).
