From the above measurements it appears that from head to tail 

 T. fossiger is only six iiiches shorter than R. unicornis^ while the 

 back is eighteen inches (.580 mm.) nearer the ground. This 

 remarkable lowering of the trunk is chiefly caused by the great 

 redu<:tion of the fore arm, fore leg and metapodials. The hume- 

 rus and femur are respectively only 90 and no mm. shorter than 

 in R. icnicornis, while the radius and tibia (typically shorter ele- 

 ments) are respectively 140 and 130 mm. shorter, and the meta- 

 carpals and metatarsals are respectively 90 and 950 mm. shorter. 

 This limb reduction is very striking. At the same time the abdom-
