The large intestine measures 34 inches from the ileo-caecal 

 valve to the anus ; its muscular coat is quite smooth, as is also its 

 mucous coat. Several round or oval agminated glands are seen in 

 the mucous membrane.

The liver (fig. 3) agrees in its lobulation very closely with that of 

 Hystrix cristata and javanica. As in these animals, the right 

 central lobe is larger than the right lateral, while the left central 

 has a small portion near the middle line of the fiver cut off, so that
