DR. P. CHALMERS MITCHELL ON THE 



rectum. The wide loop appears to belong to the part of the 

 hind- gut distad of the pendant loop, and therefore represents an 

 ansa coli sinistra. As Flower has pointed out (Flower, 1872), 

 the total length of the hind-gut is only about seven feet. Oaecal 

 and colico- duodenal ligaments are both present, but have been 

 removed before the diagram was made.

 Lettering as in test-fig. 6. 



The gut-pattern of Orycterojnis, except for the specialisation of 

 the hind-gut, has not moved far from the primitive condition, the 

 two chief changes being the lengthening of Meckel's tract and of 

 the hind-e-ut.

Family Manidse. Manis tricuspis. 



I have already figured the intestinal tract of the White-bellied 

 Pangolin (Mitchell, 1905, fig. 9). I have had the opportunity of 

 examining another example of this mammal. The pattern was 

 in all essential respects identical with that of the former example, 

 but the duodenal loop was not so distinctly marked oflf from 

 Meckel's tract, and the subsidiary coils of the latter were rela- 

 tively larger and more numerous than in my figure ; the tract was 

 very much longer than the hind-gut. A small colico-duodenal 

 ligament was present, but when that has been removed, as in the 

 figure, the primitive mesentery is seen to be complete.
