The general arrangement of the intestinal canal of li- 

 zards as it may be concluded from the descriptive notes 

 above, is as follows. The rentricle forms a long more or 

 less sausage- or spindle-shaped säck which on the left side of 

 the abdominal cavity extends to or nearlv to the inguinal 

 region. In long and slender forms it does not reach so far. 

 for instance. only half the way between axilla and groin in 

 Brnco hamatopogon and Chalcides ocellatus, and not mnch 

 further in Ch. lineatus. In the snake-like Ophisaurus the dis- 

 tanee between the pylorie opening and the rent is abont a 

 third of the distance between the latter and the snout, but 

 in the worm-like Bliineura the distance between the pylorns 

 and the vent is only two ninths of the standard measure- 

 ment. In the slender forms, as those just mentioned, Calofes 

 and Scincoids the ventricle is as a rule qnite straight. In 

 others it is a little recnrved at the pylorus. as for instance 

 in the Geckonids, Lacertids etc, more so in the Iguanids, 

 and especially much in broad and flattened animals like
