Has not been studied in detail in life. Living specimens about 1/4 inch 

 (6 mm) long, of oval-domed shaped, white, with a creamy center. Pre- 

 served animals 2-4 mm long, of oval outline, with a convex dorsal and 

 a concave ventral surface, described as being of the shape of a minia- 

 ture turtle. At the anterior end is a snout-like projection, cylindrical 

 in cross section, containing a deep epithelial invagination with glandular 

 and muscular differentiations, apparently serving as an adhesive organ. 

 The postpharyngeal region is much reduced in size. Eyes are absent. The 

 lateral margins of the body have a thick band of very large rhabdites . 

 Testes few, large, forming on either side a group located dorsolaterally 

 in the middle of the prepharyngeal region. Copulatory apparatus close to 

 posterior end. Penis with spherical bulb and elongated papilla which is 

 conical at its base and cylindrical in the distal part. The vasa defer- 

 entia enter the penis bulb, unite, and continue as a narrow canal, the 

 ejaculatory duct, to the tip of the penis papilla without forming an 

 enlargement or seminal vesicle. Copulatory bursa small, with narrow 

 stalk enlarged only in the distal portion close to the gonopore. Common 

 oviduct opens into posterior part of male atrium. Known only from 

 Malheur Cave, Harney County, Oregon. Literature: Hyman (1937b).
