 of a vein belonging to the same series, which, however, belongs to 

 the suprarenal portal system. 



Oviducal Vein. — The oviduct is borne by a membrane which is 

 attached to the lateral parietes and anteriorly passes over the

 which runs towards the line along which the oviducal membrane 

 is attached to the lung. It ends by entering the liver-substance,
