512 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [June 6, 
The liver of Prionodon differs remarkably from that of every other 
form I have examined in the much smaller relative size of the left 
central lobe compared with that of the left lateral ; so that the latter 
rises (the apex of the gall-bladder being downwards) above the 
former, and forms nearly half of the posterior surface of the liver’s 
left segment. These two lobes (the left lateral and the left central) 
are not separated, but are continuous towards their inferior margins. 
It is as if the left segment of the liver consisted only of one great 
lobe, the right portion of which was bent over so as to end in a 
free margin, to the right (on the abdominal surface) of the great 
bulk of such one lobe. 
The gall-bladder lies in a fossa, placed very much towards the 
left margin of the right central lobe. The proportion borne by the 
right lateral lobe to the right central seems to be much as in the 
Genet'. The Spigelian lobe is small and simple ; the caudate lobe is 
moderate. On the diaphragmatic aspect of the liver, the small left 
central lobe only shows a little towards the ventral margin. There 
is a deep cystic notch. 
The liver of Hemigalea is almost like that of Genetta; but its 
Spigelian lobe has no notch, its caudate lobe is smaller, and its right 
lateral lobe is rather large compared with its right central. ‘There 
is a gall-bladder, which is placed in nearly the same position in the 
right central lobe as it is in Genetta. This liver also resembles that 
of Genetta as to its diaphragmatic aspect, save that its right lateral 
lobe is rather larger and more pointed. 
In Herpestes the liver is very much like that of Genetta, save that 
in it the right lateral lobe is smaller compared with its right central 
lobe, and that its gall-bladder lies much more close to the left margin 
of the right central lobe. 
In Crossarchus the preponderance of the right segment of the 
liver over its left segment is greater than in any other form yet de- 
scribed; it is nearly as two to one. The diaphragmatic aspect of 
the liver presents the following characters :—The right lateral lobe is 
very small compared with the right central; this proportion is 
much as in Paradowurus ; but the shape is very different, broadening 
instead of narrowing to its outer margin. The right lateral lobe is 
not broad enough to hide the very large caudate lobe. The right 
central lobe has a notch, not at its ventral margin, but at its left 
end: it is a short side notch, wherein the gall-bladder appears. 
The proportion of the left lateral lobe to the left central is much as 
in Nandinia ; but they are not quite so unequal. 
On the abdominal aspect, the very large caudate lobe (larger rela- 
tively than in any form yet here noticed) is seen with a small, simple 
Spigelian lobe. The left central lobe does not appear. The left 
lateral lobe is entire, but hidden by the caudate lobe. The right 
central lobe is very large; but the excess of that part of it which is 
on the right of the gall-bladder over the minute portion on the left 
of the gall-bladder is greater than in any other form yet here de- 
scribed. Thus the bladder makes its appearance between the right
