veins, of which the left opens into the postcaval a little below 

 that of the right. These veins, however, are curiously symme- 

 trical in the details of their branching. At the opening into 

 the postcaval each is a single trunk. This immediately divides, 

 and the anterior branch gives off two twigs running in the 

 direction of the kidney ; the two branches then reunite to form 

 a single vein. In the case of Genetta vulgaris (text-fig. 214), the 

 first vein which enters the postcaval behind the liver is a branch

on the right which is the first lumbar and suprarenal vein ; the 

 corresponding vein of the left side lies a little lower down. The 

 renal veins are also asymmetrical, the right lying higher up than 

 the left. There is no accessory renal vein entering the postcaval. 

 The right renal vein gives off the spermatic. That vein of the 

 opposite side of the body enters the postcaval considerably behind 

 the left renal. The two posterior lumbar veins are symmetrical 

 and are undivided trunks.
