Fig. 36 after Kenk (1970a). 



Mature animals up to 12 mm long and 1 . 7 ram wide. Head truncate, with 

 straight or centrally convex frontal margin and rounded lateral edges. 

 Behind the head is a very slight narrowing of the body. Eyes normally 

 two, rather close together and removed from the anterior end. Dorsal 

 surface uniformly gray or somewhat mottled, ventral side lighter. 

 Cannot be separated by its external features from some other pigmented 

 species of the same genus or from Planaria daatyligera and Eymanella 

 vetenuova. Testes numerous^ predominantly ventral, situated on either 

 side in a broad zone extending from behind the ovary to the level of 

 the mouth. There is no common genital atrium developed. Penis with a 

 spherical, muscular bulb and a conical, rather stiff, pointed papilla. 

 Vasa deferentia enter bulb anteroventrally retaining their expanded 

 shape as spermiductal vesicles, form a few convolutions within the bulb, 

 and open separately into the seminal vesicle. This cavity tapers pos- 

 teriorly to a narrow straight canal, the ejaculatory duct, which opens 

 at the tip of the penial papilla. The openings of the common oviduct and 

 of the bursa stalk are close to the gonopore. Cocoon ellipsoidal, 

 unstalked. Only sexual reproduction observed. In seepage springs. North 

 Carolina. Literature: Kenk (1970a).
