HELAMYS CAPENSIS. 239 



The spleen lies in the epiploon on the left side, which epiploon is 

 attached to the left loin and kidney. The liver is small, and is divided 

 into three lobes and a lobnlus Spigelii. The ligamentum rotundum 

 enters the middle lobe : the right lobe is the smallest. There is no 

 gall-bladder. The kidneys are conglobate, with one mammilla pro- 

 jecting pretty mnch into the pelvis 1 . The capsulse renales are circum- 

 scribed oblong bodies, of a bluish-grey colour. 



The heart lies pretty much in the middle of the chest : it is flat, 

 broad, with the right ventricle rather lower than the left : it has two 

 vense cavse superiores. The lungs, on each side, are divided into three 

 lobes, which become larger downwards, with a middle lobe from the 

 right lung, and also one between the heart and diaphragm. The 

 trachea divides into two about the second or third ring from the cricoid 

 cartilage. 



The rectum, as it comes out of the pelvis, is bent down between the 

 two ossa pubis, and opens just upon the bulbous part of the urethra 

 about 2 inches from the tail. About half an inch farther between the 

 legs is another opening, similar to the anus, passing in the same direc- 

 tion between the two crura of the ossa pubis, and leading to, or termi- 

 nating in, two blind ends, between the rectum and the bulbous part of 

 the urethra. These two ends are glandular, or secrete a whitish mucus : 

 they are lined with a cuticle, are white and silky, having a good deal 

 of short white hair 2 . 



Just before this opening is seen the glans penis, directed backwards, 

 lying in a very large prepuce. The prepuce appears to be no more 

 than the loose skin on the pubis drawn in with the penis in its flaccid 

 state. 



The testicles commonly He in the cavity of the abdomen just at the 

 rings ; however, there is a passage for them to the scrotum, which is a 

 bag placed between the anus and the tail. The testicles are large for 

 the size of the animal, oblong, the upper end thicker than the lower ; 

 from which end there passes down into the tunica vaginalis communis 

 a gubernaculum, which is pretty thick. The tunica vaginalis communis 

 passes down by the side of the penis, then crosses the rectum, where it 

 is reflected downwards, and terminates in the scrotum. 



The gubernaculum is attached to the tunica vaginalis by a thin 

 membrane along its edge. The vesicular seminales are very large, 

 larger than the human, and much the same in appearance ; they are 

 almost wholly pendulous in the abdomen.
