and ventral muscular divisions. Its histological characters have 

 been thoroiighly described (6), and I have nothing to add to that 

 account. Running along the floor is a ridged groove continuous 

 with the groove from the paunch into the cardiac stomach, and 

 Rapp (10) thinks it has a ruminating function. The communi- 

 cation between pylorus and duodenum is guarded by a strong- 

 valve (Plate III. C, a), but Rapp states that there is no pyloric 

 sphincter.

A: Interior of the duodenum, b.p., bile papilla; p.p., pancreatic papilla; sp.p., 

 papilla of accessory pancreas. 



B : The spleen with accessory spleen (a) in. the pancreas (p). 



C & D : The pancreas, c.b.d., common bile-duct; p.d., pancreatic duet ; m., mesen- 

 tery ; py. , pylorus. Description of other figures in text. 



E : Section across the suprarenal capsules, cm., medulla within cortex. The upper 

 is the left, and the lower is the right capsule. 



The stomach is, therefore, very complex and contains divisions 

 corresponding to most of those of the Ruminantia, but the 

 reticulum of these animals is absent.
