26 EIGHTEENTH ANNUAL REPORT ON THE STATE CABINET. 



0. 



Head of the Dinotherium, 



longation of the symphysis of the lower jaw. The skull, scapula, femur and 

 pelvis(?) are the only parts yet discovered. The scapula resembles that of a 

 Mole. The femur, which lies on the yedestal under the head, is the largest 

 thigh-bone known to naturalists ; measuring five feet in length, and two feet 

 four inches in greatest circumference of shaft. Cuvier and Kaup calculated 

 that the animal must have attained the extraordinary length of eighteen feet. 



Professor Kaup regards the Dinotherium as intermediate between the 

 Mastodon and Tapir, and truly terrestrial ; while MM. DeBlainville and 

 PiCTET consider it an aquatic herbivore resembling the Lamantin, and in- 

 habiting the embouchures of great rivers. In the general shape of the skull 

 and aspect of the nostrils, according to Owen, the Dinotherium most re- 

 sembles the Manatee or Dugong ; " but bones of limbs have been found so 

 'associated with teeth as to determine the Dinotherium to be a hoofed qua- 

 druped, of probably aquatic habits, and transitional, as it would seem, be- 

 tween the large Lophiodorus and the huger proboscideans."
