314 ON THE CZECUM COLI OF THE CAPYBARA. 
Fig. 1. 
Sacculated and simple ceca of the Capybara. The continuation of the colon is seen 
at a. The small intestine at its termination cannot be seen, being hidden in 
the proximal angular bend of the sacculated cxcum. 
Page 21. The ileo-cwcal valve is linear and longitudinal ; it projects a short 
distance into the sacculated czecum from above as a tube with slightly 
turned lips, of which the inferior is a little the longer and larger. 
There are some thickened gland-patches in the sacculated caecum, and 
a large one in the colon, at the margin of the sphincter which is towards 
the continuation of the large intestine; three or four others are situated 
irregularly in the walls of the true cecum. 
The disposition of the colon is peculiar and interesting. The 
accompanying sketch (fig. 2) will explain it best. It was taken from 
the view obtained of them as the animal lay on its back. As is well 
known, the large intestine commences in the left hypochondriac region, 
the true cecum capping the end of the sacculated one anteriorly. The

region, where, with a reversed figure-of-eight twist, it gets into the 
normal position of the ascending colon, It so reaches the right hypo- 
chondriac region, and then commences to form, in the transverse colon, 
coils very similar to, though on a smaller scale than those in Indris 
among the Lemurs and in the Artiodactylate Ungulata, the much- 
developed loop being twisted on itself to the left side. After reach-
