testine wbicli measures 152 mm. in length and has a longi- 

 tudinally plicated mucosa. There is a well developed coäciim 

 consistiiig of a wider basal portion and a narrower blind 

 säck measnring 8 mm. in length and 4 mm. in width. The 

 small intestine opens sinistroventrally into a wide eoccocolic 

 dilatation as is seen on the figures (Fig. 2 and 3, Pl. I). 

 From the same it can also be concluded, that the arrange- 

 ment and shape of these organs are similar to those of Fty- 

 chozoon althongh perhaps a greater portion of the coeoum is 

 seen on the left side of the mesentery in the Geclco. The 

 length of the large intestine is about '2^ mm. and it is al- 

 most straight. The ventricle contained beetles, some of whieh 

 were qnite large. In the comparatively wide small intestine 

 some large pieces of the beetles as elytra etc. are seen here 

 and there. The large intestine contained a mäss of crnshed 

 remains of the chitinous integument of insects and in one of 

 the specimens dissected these remains seemed to have been 

 snbjected to some secondary cru.shing action as the pieces 

 were rather small, only the thick femnr of a beetle and the 

 rolled up wing, also of a beetle, conld be identified. From 

 these facts it becomes evident that the insects are swallowed 

 whole and almost nnbroken. By the action of the muscula- 

 tnre of the ventricle they are broken up in pieces large 

 enough to pass throngh the small intestine. In the large in- 

 testine or rather its ca3cocolic tract the remains are kept for 

 some time and squeezed whereby the chitinous pieces may 

 get still more broken and the digestible parts are, together 

 with the fluid. reabsorbed perhaps to the greatest extent by 

 the coecal blind säck. 



A somewhat similar arrangement of the coccum as in 

 this lizard has been described by Meckel^ from Gecho vittatus.

The ventricle is spindle-shaped, ju.st a little recurved at 

 the pyloric end wbich lies in the inguinal region. The be- 

 ginning portion of the small intestine is much wider than
