is 1.5 mm. long and 5 mm. wide. The greatest body width is in the 

 region of somite 6, where the diameter is 6 mm. The somites in 

 general are about 0.75 mm. in length ; the body is 95 mm. long, with 

 approximately 120 somites. It tapers rapidly toward the posterior 

 end, but no trace of anal cirri remain. Throughout the posterior half 

 the dark dorsal blood vessel and anastomosing blood vessels on the 

 dorsal surface of each somite give a dark color to the dorsal surface.

 chestnut colored at the apex. The teeth are not very distinct, but
