corresponding organ in Proteles^. The soft palate is short, and 

 presents no trace of uvnla, such being the case likewise in Proteles. 

 The oesophagus, as noted by MeckeP in the specimen examined by 

 him, is wide and dilatable. Its muscular walls are very thick, as is also 

 the mucous coat, the latter being dense, tough, and thrown into 

 longitudinal rugae. 



Stomach. — The stomach is short and rounded, and corresponds 

 exactly as regards form with the description given by Daubenton^ 

 and Murie'' of that organ in H. striata^ and H. brioinea respectively, 

 and by Professor Flower* in his observations on Proteles. When 

 emptied of its contents, it measures 9 inches in length and 7 inches

in greatest breadth. The oesophagus enters the small curvature 

 close to the left extremity ; and in consec|uence the great end or 

 fundus of the stomach is extremely shallow. The greater curvature 

 presents a slight constriction close to the pyloric extemity, similar to 

 that noticed by Prof. Flov/er in Proteles. The walls are thick and 

 muscular, as in H. brunnea and Proteles. Dr. Murie recognized 

 in the former a central tendon, from which the muscular fibres
