The funnel itself is particularly well supplied with blood, 

 more especially the dorsal lip, which is traversed by one of the 

 main branches of the nephridial vessel, as shown in the figure ; 

 the other branch [a') passes along the gonad, which is not 

 figured, and enters (at b) the general network in the 

 nephridium. 



A portion of this network is exhibited at fig. 34, which is an 

 enlarged view of the vessels on the neck of the funnel. 



This network is present in many Polychseta, as Cosmovici 

 and others have pictured.
