small intestine is 51 mm. Its mucosa is longitudinall}^ pli- 

 cated. It opens excentrically into the large intestine the ca>- 

 cal säck of which is, thanks to the conipressed shape of the 

 abdominal cavity, directed dorsalh'. The length of the large 

 intestine is about 13 mm.

The ventricle is straight and liniited by a valve from 

 the widened duodenal portion of the small intestine. The 

 latter measnres abont 140 mm. in length and the large in- 

 testine about 50 mm. There is a rather strong sphincter be- 

 tween the two, bnt no valve. To the left of the opening of 

 the small intestine into the large one there is a large säck 

 representing a coecum. It is more differentiated than in Go- 

 nycephalns but has similar mesenteric connections. Its width 

 is about 9 and its length abont 8 mm. The intestine con- 

 tained remains of insects. 



Meckel^ recorded a coecum in a Calotes in the shape of 

 a ;.sehr enger Fortsatz». This depended perhaps npon the 

 emptiness of the organ.

Distance from snout to vent 93 mm. 



The ventricle sausage-shaped and extending to a distance 

 of about \ 2 cm. from the groin. There is a short thinwalled 

 pyloric tract of the ventricle. 



The length of the small intestine is about 122 mm. Its 

 mucosa is longitudinalh^ plicated. There is a short coocum 

 widely rounded and in full connection with the colon, its 

 length is about 5 or 6 mm. The end of the colon is sharpl}^ 

 bent back upon itself so that the ccecal end lies on the left 

 side of the other part. The length of the whole large intes- 

 tine is about 55 mm. 



There are no valves in the colon, but at the bend the 

 adjoining parts of the vvalls are fused so that there is formed 

 something similar to a semilunar valve.
