in Proteles; whereas in Daubenton’s Hyena it was more than eight 
times, and in one dissected by Reimann between six and seven times. 
The liver (figs. 7 and 8) is large and deeply subdivided. As usual 
in the Carnivora, its main divisions are three, of about equal size :— 
1. The left lobe (ZL) is simple, flattened, rhomboid, without subdivi- 
sions. 2. The middle lobe (M and Q) is broad, deeply cleft at the 
umbilical fissure into two pointed tongue-shaped pieces, of which the 
left (Q) is the smaller. The right portion (/) has the gall-bladder 
(B) attached to the left side of its under surface, its fundus project- 
ing beyond the margin of the cleft. Between these two portions is 
a small accessory lobule. 3. The right lobe (2) is pointed, or, 
rather, heart-shaped ; near its upper edge are attached two accessory 
lobules—the Spigelian lobe (S), conical, pointed, and projecting 
backwards, and another (fig. 8, 4), rather larger, with a truncated 
notched edge, turned to the right. On the under surface of the lobe, 
near the apex, is a triangular pointed prominence—a sort of second 
apex. The outer (right) border has two notches. 
The entire width of the liver, when lying on a flat surface with 
the lobes spread out, is 8. The left lobe is 4'-6 long, and 2''-6 
broad; the middle lobe 3'9 in greatest length, and 3!'"6 broad ; 
the right 4'-4 long, 3" broad. 
The gall-bladder was of a simple pyriform shape, without any 
Upper surface of liver; half the natural size.
