Remarks. There are 23-27 segments. The body does not as a rule taper gradually to 

 the anal cylinder, but the latter comes off rather abruptly from the terminal segment. It is 

 equal in length to the last four segments. The posterior part of the body with the lateral 

 eminences has 10 to 11 segments and not 15 to 16, as in T. olens. The edges of the 

 terminal segments may be divided into areas as described by Benham [loc. cit.), or they 

 may be faintly laciniated (Fig. 67, a), or again deeply serrated (Fig. 67, b) : finally, these 

 serrations may be modified into large spike-shaped papillae (Fig. 67, c). At the other 

 end of the series the terminal segments may be perfectly smooth, and apparently 

 associated with this condition is found a pair of dorsal anal cirri at the end of the anal 

 cylinder. It is possible that these anal cirri may have been present but lost from the 

 papillated and laciniated examples. For the specimens with smooth terminal segments 

 and anal cirri I propose to create a new variety.
