Fig. 84 after Kawakatsu (1968). 



Has not been studied in life. Description was prepared from one mature 

 and one immature specimen in defective condition. Unpigmented (in life 

 "translucent pink"), eyeless, up to 14 mm long and 2 mm wide. Anterior 

 end with subterminal adhesive organ forming a depression with glandular 

 and muscular differentiations. Testes numerous, of moderate size, 

 ventral, extending posteriorly to the base of the pharynx. Penis with 

 highly muscular spherical bulb and conical pointed papilla. Seminal 

 vesicle divided into a pair of elongated cavities, each receiving one of 

 the sperm ducts anterolaterally. The two cavities unite at the base of 

 the papilla from where a rather narrow ejaculatory duct proceeds to the 

 tip of the papilla. The common oviduct opens into the posterior part of 

 the male atrium from the dorsal side. There is no common atrium devel- 

 oped. The outstanding specific characteristics are the lack of eyes 

 and the division of the seminal vesicle. Known only from Lake Tahoe, 

 California and Nevada, from a depth of about 1600 feet. Literature: 

 Kawakatsu (1968).
