Show 512 PROF. ST.-GEORGE MIVART ON THE JELUROIDEA. [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 Genet1. 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 m u c h 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 described; it is nearly as two to one. The diaphragmatic aspect of the liver presents the following characters : - T h e right lateral lobe is very small compared with the right central; this proportion is much as in Paradoxurus ; 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. O n the abdominal aspect, the very large caudate lobe (larger relatively 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 j but the excess of that part of it which is on the right of the gall-bladder over the minute portion on the left ot the gall-bladder is greater than in any other form yet here described. Thus the bladder makes its appearance between the right 1 The liver of the specimen examined was injured in this region. |
