Uroniastix is, as is wellknown, herbivorous and the for- 

 mation of the coeco-colic säck is an adaptation to this diet. The 

 stomach of the aninial dissected contained pieces of grass 

 (chiefly the ilowers and grains) and the coeco-colic säck the 

 same material in a greatly decomposed stage althongh evi- 

 dently the coarsest fibre cannot be digested.

The ventricle reaches nearly to the inguinal region -svhere- 

 it is a little reciirved and opens into the wide beginning por- 

 tion of the small intestine. The length of the latter is about 

 12 mm. The small intestine opens on the right side into the 

 large intestine and a well developed coecum is present to the 

 left. It measnres 2^,2 mm. in length and 1^/2 in width, and 

 is directed straight forward. The large intestine inclnding 

 the coecum measnres 18 mm. There are no valves but in the 

 posterior part some transverse folds are visible. I ani, however, 

 nncertain if these are constant or not. The auimal is as is 

 wellknown insectivorous. The large intestine contained the 

 cast skin of the animal itself.^

The ventricle reaches nearly to the groin and it is hardly 

 recurved at the pylorus. The beginning part of the small in- 

 testine is abruptly widened so that it seems almost to pro- 

 trnde like a eoocal säck beyond the pylorus. The length of 

 the small intestine is about 74 mm., but the material is not 

 well preserved. The large intestine has attained a great de- 

 velopment and is doubled up on it self on the median side 

 so that the short but wide coecum is directed backwards. Its 

 length along the curvature is about 36 mm. 3\2 of which 



' That some lizards and salamanders f. i. Pleiirodeles tcalti devour 

 their ovrn cast skins has been observed several times.
