The gizzard and duodenum were filled with short pieces of sedge 

 ( Carex) and Uncinia. 



The liver-lobes present the usual inequality. The gall-bladder 

 is an oval sac, completely outside and free from the liver ; there 

 are the two usual ducts, one the " cystico-enterie," the other the 

 " hepato-enteric." The pancreas is provided with two ducts, one 

 from the dorsal lobe and the other from the ventral lobe, as we 

 may term those parts which lie on each side of the mesentery, as 

 the duodenum lies spread out in the normal way, though no doubt 

 right or left would be more appropriate. 



The ventral lobe of the pancreas terminates anteriorly in a freel}' 

 projecting fiuger-like process. 



Both the ducts arise at the hinder end of the pancreas, pass 

 directly across the mesentery, to open close to the two liver-ducts 

 into the distal limb of the intestine (fig. 1, Z, g^p). 



(b) The Tongue (fig. 2). — The acute tip of the tongue is beset 

 with a series of short brown cylindrical horny spines (s), which

At the base of the tongue is a transverse, slightly curved ridge,
