the valves the capacity of the colon decreases iu a conside- 

 rable degree. 



This lizard feeds on vegetable matter. The ventricle 

 contained a large fruit 5^/o by '2'^l'i cm., large (ÖV^ cm.) fun- 

 nelshaped flowers etc. The contents of the coh)n was a black 

 (somewhat purplish) mäss. In this mäss large pieces of the 

 corolla of the above mentioued flower could be distinguished 

 in a more or less decomposed stage. It is thns in this part 

 of the intestine where the decomposition and digestion of 

 snch kind of food takes place and the arrangement with val- 

 ves although less developed than in the Iguana is a sui- 

 table adaption for this fnuction. This lizard is said to be 

 omnivorous (conf. Boulenger; Cat. of Lizards Brit. Mus. II, 

 p. o), bnt even if this reall}^ is the case its intestine shows 

 prominent adaptations to a vegetative diet. 



Conoloplius siibcristatus Gray. 



Distance from snout to yent about 455 mm. 



The specimen is in no good state of preservation. The 

 empty ventricle seems to measure more than 30 cm. in length 

 but it is not easy to see its limit towards the oesophagus. 

 It is not dilated but sansage-shaped. At the pylorus is a 

 well developed circular valve about 8 mm. in breadth and 

 the mnscnlatnre of the ventricle ceases a couple of centimetres 

 above this. The small intestine which is narrowed posteriorly 

 measnres 131 cm. in length. There is no coecum, when the 

 large intestine is empty, but the opening of the small in- 

 testine into the colon is a little excentric and there may 

 thus be formed an excentric dilatation when the colon is fil- 

 led with food-material. The large intestine measnres about 

 56 cm. in length. The opening of the ileum into the colon 

 is surrounded by a valve. About 4V2 cm. from this opening 

 there is a strong diaphragma-like valve extending all ronnd 

 the colon with a width of 3^2 cm. on the mesenteric side, 

 1V-' cm. on the opposite. Four cm. from this one is the next 

 valve which on the mesenteric side attains a height of about 

 4 cm. but it does not extend across the colon. The length 

 along the free inner margin is 6V2 cm. Next valve is found 

 in a distance of 3 • 2 cm. from the second. This third valve 

 is also high on the mesenteric side, about 3 cm., but is only
