It is chiefly remarkable for the shortness of the femur as compared with the length of the 

 tibia, which is much increased by the development of the epicnemial process, formed by the 

 convergence and union of the pro- and ecto-cnemial ridges, in the line of the axis of the 

 shaft, half way down which the procnemial ridge b continued. The fibula is of unusual 

 length ; the metatarsus is singularly compressed.

1167. The skeleton of the common Pelican (Pelecanus onocrotalus). 



There are 1 9 vertebrae between the skull and sacrum, the last three of which support 

 moveable ribs : of these the first pair is free and floating ; the second and third pairs, like 

 the fourth, fifth and sixth pairs of ribs, which are attached to the sacrum, are articulated by 

 bony hsemapophyses to the sternum. All the ribs, save the first and last, have bony appen- 

 dages, and from the hsemapophyses of the last pair a bony projection passes backwards. 

 There are 7 caudal vertebrae. The anterior dorsal vertebrae support feeble rudiments of 

 hypapophyses.
