These two species were first referred to the genus Megascolex, to 

 which they have clearly many points of likeness. There are 

 regular or irregular lines upon the dorsal and ventral surfaces 

 which are unoccupied by setae. In any case these two species 

 cannot be confounded with any others. There are no penial setae. 

 Por this reason and the position of the gizzard, the two forms 

 appear to be rightly placed in the present genus. 



F. Spermathecae 2 pairs in vii., viii.
