membrane of the gizzard in birds, is raised into eight longitudinal folds. A 

 finer arrangement of the longitudinal folds marks distinctly the commencement 

 of the stomach, which terminates in a sharp point. The pyloric valve is placed 

 about the centre of the stomach, and presents a complete obstruction to 

 any thing passing to the intestine, independently of the vital phenomina. The 

 duodenum, and the remainder of the intestinal tube is distended, but gradually 

 contracts, and becomes nearly straight. 



The duodenum, when divided longitudinally, exhibited a finely reticulated, 

 honey-comb surface. No vestige of pancreatic cceca could be detected. 



The fiver, square-shaped, lay imbedded, as it were, between the oesophagus 

 and intestine ; it was of a pale brownish-yellow colour, soft and friable. 



The kidneys, in position and structure, resembled those in the anatomy of 

 the Muroena. 



FOOD. 



No organic remains could be detected in the stomach, or intestinal tube, 

 and the utter absence of any fatty deposit was sufficiently curious ; perhaps 

 the specimen had just emerged from its winter quarters in the mud. 



GENERATIVE ORGANS 



resemble those of the eel, and being in their minimum state of development, 

 or season, some difficulty occurred in even determining the sex.
