Terrestrial Planarians from Japanese Territories. 47 



The ground colour of the dorsal surface is uniformly light 

 black with a slight touch of reddish tint, in front grading over into 

 a red or yellow tone at the tip of the body. Extending over the 

 surface is a fine black median stripe, which loses itself in front. 

 The dark tone is carried to the ventral side with little difference in 

 shade except for the mid-ventral surface which is pale. 



The small eyes, which are two in number, occur on either 

 side at the anterior tip of the body. 



The mouth-opening is situated near the middle of the body, 

 leading into the peripharyngeal pocket with the cylindrical 

 pharynx.
