Fig. 54 and 55 after Hyman (1945), 

 modified . 



Preserved specimens 5-6 mm long. Anterior end truncate, without auric- 

 ular extensions. Eyeless, in life presumably white. Body margins with 

 large rhabdites. Adhesive organ at center of frontal margin, consisting 

 of a depression of the epidermis through which eosinophilic glands open, 

 surrounded by an arrangement of mostly radial muscle fibers. Testes 

 rather few, in a pair of longitudinal rows, prepharyngeal . Copulatory 

 complex excessively glandular. Vasa deferentia open into a small chamber 

 (seminal vesicle?) apparently before entering the penis bulb. From this 

 chamber the narrow ejaculatory duct traverses the bulb and the short, 

 rounded penis papilla, widening in the papilla. Epithelium of the 

 papilla tall and glandular. Male atriiun separated from the common atrium 

 by a constriction. The common oviduct opens into the posterior part of 

 the male atrium. Copulatory bursa rather small, its duct with irregular 

 enlargements, glandular in its distal portion. Cave in Alabama. 

 Literature: Hyman (1945).
