right renal and the right posterior ovarian vein four median inter- 
costal veins opened into the postcava. These veins appeared to 
me to be particularly slender. 
In Macropus hagenbecki the renals were nearly symmetrical, 
and so also were the posterior spermatics; the anterior spermatic 
veins were present.

Postcaval vein and its branches in Macropus parryi (A) and 
Macropus agilis (B). 
In the latter the spermatic arteries are shown emerging from the concealed 
aorta just below the posterior spermatic veins. 
Lettering as in text-figs. 1382, 133. 
Macropus agilis agrees very closely with I. parryi. The lett 
suprarenal flows into the left renal near to its entrance into the 
posteaval. The two vessels accompanying the ureter appeared to 
me to anastomose, one of them at any rate and that on the left 
side, with the posterior ovarian vein. The posterior ovarian veins
