764 PROF. W. H. FLOWER ON A‘LURUS FULGENS. [ Nov. 15, 
right lobes, is deeply divided by the fissure, through which the round 
ligament (u) passes, into a left and right portion ; the former (1°) 
is subtriangular, with a pointed free extremity, and not further sub- 
divided ; the latter (JZ') is rather the larger of the two, and, very 
near its left border, has a deep cleft in which the gall-bladder (B) is 
situated, the fundus being visible on the upper surface of the liver in 
this cleft. There is thus a distinct, narrow, tongue-shaped lobule 
(A) between the umbilical and the cystic fissures*. 3. The right 
lobe (A) is rather smaller, though thicker, than the left, and of a sub- 
quadrate form. It has the usual two accessory lobules on its under 
surface—the pyramidal pointed Spigelian lobule (S), and a remarkably 
large caudate lobule (4), grooved above for the inferior vena cava, 
and projecting beyond the right lateral margin of the main superior 
division of the lobe 7+. 
The inferior vena cava (vc) perforates the upper or posterior border 
of the right lobe, running for a distance of an inch and a half under 
a bridge of the hepatic substance, at its emergence from which it is 
joined by the hepatic veins. 
The gall-bladder is of the usual pyriform shape. The commence- 
ment of the duct is sharply bent upon the neck of the bladder, and 
it makes another sharp bend in the contrary direction at the junction 
of the hepatic ducts. Its fundus (B) appears on the upper surface 
of the liver in the cleft between the divisions of the lobe marked M’ 
and M? in the figure. It also displaces the substance of M’ a short 
distance to the right of the fissure, and appears on the surface only 
covered by the external capsule of the liver. 
The spleen is elongated and perfectly simple, without any notch or 
fissure, rather broader at the lower than at the upper end. Its length 
is 57", and its greatest breadth 1”. 
The right kidney is placed very slightly higher than the left. 
‘These organs are perfectly simple, having no indications of division 
into lobuli on their surface. The length of each is 1:9", its greatest 
breadth 1:1". 
The suprarenal bodies are placed close to the upper end of each 
kidney ; they are small, oval, and somewhat flattened, = 30 itl 
greatest length. 
Pexivic VIscERA. 
Organs of generation.—Externally the generative organs are 
small and inconspicuous (see fig. 9). On the hinder part of the 
under surface of the abdomen, 23 inches in front of the anus, is a 
short conical prepuce, directed forwards, and projecting scarcely 
more than 4 inch above the level of the surrounding skin ; it is 
nearly naked, and pale-coloured, but it has a few long stiff hairs 
growing around the orifice on its summit. Behind this the penis 
forms scarcely any appreciable median prominence. There is no 
proper scrotum; but the testes form distinct rounded prominences, 
about 3} inch in diameter, under the skin, with a flat interval of 
* In Nasua this is of relatively larger size. 
+ In Nasua the proportions of these lobules are very similar,
