composed of a median stem which divides into two at about the 
middle of the total length, the transverse branches, in the neighbour¬ 
hood of the intestinal caeca, dividing again each into an anterior and 
a posterior branch which run for the greater part outside of the 
intestinal caeca, and terminate in the neighbourhood of the antenor 
and posterior extremities of the body Testicles lateral, at about the 
same level but far apart from one another Copulatory organs well 
developed ; cirrus pouch thick, almost cylindrical, containing a long 
but rather thin seminal vesicle and an equally long and thin ejacu 
latory duct which both describe a number of coils within the pouch. 
Vagina corresponds in length and arrangement to the ejaculatory 
duct. Structure of the remaining organs as in Dierocotlium
