Fig. 56 and 57 after Hyman (1954), 

 modified. 



Described from two defective specimens. Preserved animals about 8 mm 

 long. Head truncate, with a central adhesive organ. Blind and un- 

 pigmented. Adhesive organ is a subterminal cuplike depression with 

 outlets of eosinophilic glands and longitudinal retractor muscles. 

 Testes small, ventral, forming on either side a band occupying the 

 posterior half of the prepharyngeal region. Penis with muscular bulb 

 and conical papilla. The vasa deferentia enter the bulb ventrolaterally 

 and open separately into a rounded seminal vesicle. This continues 

 posteriorly as a straight ejaculatory duct to the tip of the papilla. 

 The common oviduct opens into the roof of the male atrium. Copulatory 

 bursa not studied. Bursal duct narrow in its anterior portion, pro- 

 ceeding posteriorly beyond the gonopore, then turning abruptly antero- 

 ventrally and widening considerably. This widened portion, interpreted 

 best as a vagina, is surrounded by a thick layer of chiefly circular 

 muscle fibers. Known from a cave in Georgia. Literature; Hyman (1954).
