up than the right. Hach renal vein, when close to the kidney, 
divides into two branches, one lying above the other, which supply 
respectively the dorsal and ventral side of each kidney, over the 
surface of which they ramify, as is so usually the case among the 
Aluroidea. This difference of symmetry in the renal vein is cor- 
related with the fact that in Galidia the left suprarenal flows into 
the postcaval independently of the left renal, whereas they join 
in Galidictis. Furthermore, there are no additional renal veins 
such as are present in G‘alidictis. The spermatic veins arise as 
in Galidictis (and indeed most mammals), the left from the left 
renal, the right from the postcaval vein considerably below the 
entrance into the latter of the renal veins. Two intercostal 
veins flow into the dorsal surface of the postcaval between the 
left renal and the right spermatic vein, each of them, however, 
very nearly corresponding in the point of entrance to the point 
of entrance of those two veins. The postcaval receives lower 
down two lumbar veins on each side, as in Galidictis. The exact 
disposition of these veins in Galidia elegans is as follows :—On 
the left side there are two veins, each of considerable width, which 
lie respectively above and below the corresponding artery, which 
therefore emerges from the aorta between them ; before passing 
respectively anteriorly and posteriorly the two veins are joined by 
a bridge which passes over the artery just before it divides. On 
the right side the two lumbar veins unite just before opening into 
the postcaval, and they are not united by a bridge distally. 
In an example (text-fig. 130 B, p. 488) of Suricata tetradactyla 
I found a closer agreement with Galidictis than with Galidia. 
There were two renal veins on each side, arising and ending 
precisely as I have figured them in Galidictis. The right ovarian 
vein, though pouring its contents into the postcaval itself as in 
most other Carnivora, reached that vein rather nearer to the left 
renal than in either Galidictis or Galidia. 
In another example of Stwricata (text-fig. 130 A) the conditions 
were In many points the same, but in others a little different. 
On the right side the renal veins were two, though ultimately 
reaching the postcaval by a common trunk. The renal was single 
on the left side, and this vein was more symmetrical with its 
fellows of the right side than in the first specimen. There was 
in this specimen an unusuai origin of the left ovarian vein. The 
right was as in the last specimen. The suprarenal of the left 
side was, as often in Carnivores, an important parietal vein to 
begin with, of which the actual suprarenal twig is only an 
affluent. Into the conjoined parietal and suprarenal, before it 
flows into the renal vein, open two parallel ovarian veins (as in 
Marsupials), which thus cross over the left renal and do not open 
directly into it. The two lumbar veins posteriorly are single and 
symmetrical in their points of opening into the posteaval. 
A dissection of two examples of Crossarchus fasciatus showed 
that the ovarian veins were disposed precisely as in Galidia and 
Galidictis, The renal veins were single.
