Several specimens were obtained from Sphagnum, near the Raven's 

 Well. They were very minute, 1-2 mm. long, and consisting of only 

 about 11 segments. No sexually mature forms were found. Numerous 

 spherical corpuscles were observed, floating freely in the ccelome. There 

 was practically no difference between the ventral setae of the anterior 

 and posterior segments.
