CCELOGENYS FULVUS. 217 



The kidneys are conglobate, long, round, not flat, nearly of an equal 

 height ; each has one mammilla 1 . The capsula renalis is a long small 

 body, lying close to the inner edge of the kidney above the entrance of 

 the vessels ; its internal substance is very dark. There are two venae 

 cavse superiores. 



There is a lobe of the lungs between the heart and diaphragm ; 

 besides which there are three lobes on the right side, and only two on 

 the left : the lungs of both sides are a good deal fissured. 



The external parts of the female organs of generation are like those 

 of a rat, or rather of the guinea-pig. The clitoris is an external pro- 

 tuberance bike the rat's ; having two glandular bodies as in that animal, 

 behind which is the vagina. 



The anus is continued under the tail, as in the rat, but turns down- 

 wards towards the perineum. About the verge of the anus, just under 

 the skin, there are a vast number of small glands ; and on each side of 

 the verge is a flat gland whose duct opens just where the gut and skin 

 join 2 . The vagina is large, dense in its coats and smooth on the inner 

 surface. There is one os tincse, but the common uterus to both horns 

 is very short : the two long horns pass up the loins. The ovaria are 

 oblong, yellow, and spotted, having a capsule with a wide mouth, and 

 the fimbriae on the edge of the opening. 



Of the Male Parts. — It is retromingent ; the penis is full of spikes, 

 with the points turned towards the root of the penis 3 . The testicles 

 are within the abdomen close to the rings. The spermatic artery passes 

 in. a broad membrane, and not on the edge of it, but about the middle ; 

 so there is a considerable breadth of the membrane, as it were, beyond 

 the vessels ; on the left the outer edge of this membrane is attached 

 to the lower end of the left kidney, near to the testicle: it is very 

 loose, more than 4 inches broad. 



Although the testicles appear to lie easily in the abdomen, yet they 

 can easily pass into a sheath formed for them, which is in what we 

 would call the ' rings,' being the place of the spermatic cord in other 

 animals ; which sheath is invertible into the abdomen like the finger 

 of a glove, and forms the gubernaculum. 



The epididymis comes out from the testis by a small neck of some 

 length, then forms the ' head,' then becomes very small, and at the 

 lower part it becomes large again, and is more attached to the lower 

 part of the body of the testis than is the head. The vasa deferentia 

 are small, and of course short, from the situation of the testicle. The 

 vesiculse seminales are pendulous, being only attached by their outer
