them at the end of my paper. In 1897 two other species at least 

 were added to the lists as follows : — 



5. Fridericia hisetosa Levinsen. 



As the name implies, this species has only 2 setse in each 

 hundle. It is often small, varying in length from 5-20 mm., with 

 about 60 segments. The brain is nearly double as long as broad, 

 and the peptonephridia are only slightly branched, if at all. The 

 dorsal vessel begins in segment 18, and the spermathecse have 

 2 diverticula.

6. Fridericia ratzeli Eisen. 



Setse 6-8 in front and 4 behind. Brain convex before and 

 behind, somewhat longer than broad. Peptonephridia much 

 branched. Spermatheca with small ampulla, 6-8 small diverticula 

 and long, narrow duct with glandular opening.

7. Fridericia agricola Moore. 



About 65 segments, half an inch or more in length, the 

 American specimens being 20-25 mm. Setae, usually more in 

 ventral than in dorsal bundles, 2-3 strong ones behind, in front 

 2-3 dorsal, 3-6 (seldom more than 5) ventral. Salivary glands 

 branched ; spermathecte with long duct, no glands at the opening,
