Genus Gypogeranus. 



1671. The skeleton of the Secretary Buzzard (Gypogeranw Secretarius). 



Of the 19 vertebrae between the skull and sacrum, the last five bear moveable ribs, of 

 which the four posterior pairs unite with the sternum : there are two pairs of sacral ribs, 

 which also articulate with the sternum. The sternum is pointed behind, and shows only a 

 feeble trace of two notches. The chief peculiarity in this species is the great length of the 

 tibiae and metatarsi, which present grallatorial proportions : these relate to the characteristic 

 and peculiar food of this bird, which consists of snakes, the venomous species of which are 

 thus held down at a distance from the trunk whilst being despatched by wounds from the 

 beak. In this specimen the apex of the furculum has coalesced with the keel of the ster- 

 num, which also shows an abnormal development of bone along its margin.
