pendix (Fig. 7 p c) about 8 mm. in length, wliich is directed 

 with the l)lind end backwards on the riglit side of tlie for- 

 ward directed p^dorus. There is a well developed coccum 

 measuring 11 mra. in length. It is perfectly recnrved (comp. 

 lig. 7) so that its blind end is directed forward parallel with 

 the colon. It lies on the right side of the mesentery which 

 forms a strong ligament from the basal crocal portion to the 

 back of the abdominal cavity. In consequence of the short 

 and broad shape of this lizard the proximal part of the large 

 intestine is bent back npon the distal part so that a colon 

 and a rectum can be spöken about. A resnlt of this bend- 

 ing is that the ileal opening lies on the left side ofthecolic 

 tract and that the recnrved coecum becomes directed forward. 

 The large intestine is very wide and its entire length is 

 abont (50 mm. The ileocolic opening is provided with a sphinc- 

 ter and projects only a little into the colic cavity. This 

 latter is sniooth withont valves with the exception that a 

 lip-like valve is present at the bend between the coecum and 

 the colon. The colon contained elytra of beetles and other 

 chitinous remains of insects, sand etc. The middle part of 

 the large intestine is constricted and therefore shows longi- 

 tudinal folds interiorly. The rectal portion is' again dilated 

 with similar contents as those of the true colon, but they 

 are more baked together and dry in the rectum. The func- 

 tion of the colon with the crocum is accordingly of a reab- 

 sorbing and desiccating natnre.

The length of the whole intestine is about 200 mm. of 

 which 57 mm. is the length of the large intestine. The in- 

 teriör of the small intestine shows a great number of longi- 

 tudinal wavy folds. There is no trace of any cfficum. The 

 small intestine opens into the anterior end of the short and 

 straight large intestine and is limited from the same by a 

 strong sphincter. The large intestine has a thick muscular 

 coat. In its present empty state it is laid in large longi-
