estimate the height of these animals from the skeleton. In almost all 

 eases of mounting these animals in museums the tips of the dorsal spines 

 are unduly elevated above the superior spine of the scapula, which gives 

 an exaggerated estimate of the height.

Hippopotami. — The hippopotamus is the invariable companion of the 

 southern elephant and later of the Elephas trogontherii; it survived even 

 in northern Europe until the middle of the Third Interglacial Stage. 

 Outside of Asia the oldest hippopotamus remains known are from the 

 Lower Pliocene of Gravitelli in Sicily; 44 it is compared by Seguenza 

 (1902) with the H. sivalensis of India but is clearly distinct from this 

 species. The H. hipponensis of Gaudry is confined to the Middle Plio- 

 cene of Xorth Africa and throws no light on the phylogeny of the hippo- 

 potami. These animals appear in the Lower Pliocene of India and of 

 Sicily and in the closing Pliocene of Italy, India, and Worth Africa and 

 perhaps China; in the Quaternary they spread into Java, India, Mada- 

 gascar, Africa from north to south, the Mediterranean Islands, and from 

 Spain and Italy on the south to England and west Germany on the north. 

 Until additional data are secured it is difficult to decide whether this 

 family originated in Africa (Stehlin, 1899) or in Asia (Schlosser, 1903).
