10 TNTESTINE AND DIET OF REPTILES. 



intestine is 55 mm. It opens on the right side of the large 

 intestine about 5 mm. from the anterior l)lind end of this 

 organ. There is thus formed a rather large ca3cal säck which 

 in its present filled condition is 4 mm. broad and shows a 

 somewhat to the left recurved end. The greater part lies to 

 the left of the mesentery. The length of the large intestine 

 (ca3cum included) is 24 mm. It contained remains of insects, 

 chiefly beetles. 



A coecum in the genus Draco is already mentioned by Tiede- 

 MANN 1811 and has aftervvards been recorded by various au- 

 thors as Meckel 1877, Carus and Otto a. o. All these seem, 

 however, only to have dissected yyBraco viridis:^ (= volans). 

 Ytovq. the statements above is apparent that the coecum is 

 somewhat difi'erently developed in diiferent species.

There is a well developed sphincter and valve at the py- 

 lorus between the ventricle and the largely widened begin- 

 ning part of the small intestine. The small intestine mea- 

 sures about l(iO mm. in length and its inner surface is longi- 

 tudinally plicated. There seems hardly to be any real coecum 

 when the intestine is empty, but the small intestine opens a 

 little excentrically to the right in the large one so that a 

 sinus or säck is formed to the left of the ileocolic opening. 

 This säck corresponds, however, with a coecum and is when 

 distended with food-material about 8 cm. broad (Fig. 4). It is 

 by a mesentery as weil fixed to the back of the abdominal 

 cavity as also united with the mesentery of the small in- 

 testine. The greater part lies perhaps to the left of the me- 

 senteric attachment. The large intestine is straight and 

 rather wide. Its length is about 45 mm. The contents of 

 the ventricle as well as that of the large intestine consist 

 only of remains of insects so that this lizard is apparently 

 insectivorous.
