DIET ADAPTATIONS IN YARANUS NILOTICUS. 83 



responds to the ceecal rudiment with the same situation in 

 other Varani (for instance V. grisens) in which it is better 

 visible because the width of the small intestine differs more 

 from that of the large one than in this lizard. 



The shortness of the large intestine in V. niloticus seems 

 to be a point in which it differs from related forms and 

 this may also stånd in comiection with the different diet.
