 consists of a muscular cushion containing muscular Strands mostly 

 radiating from the base of the bulb, but also running in a periphal

 glandulär cells arranged in sets, which open onto the basal surface 

 of the penial bulb. The sperm-ducts penetrate the bulb but the glands 

 in the bulb do not open into the ducts. Setae sigmoid in four fascicles 

 on each somite. No dorsal pores" für Mesenchytraeus; Eisen p. 11.
