The Skeleton. 



Although I have not now the opportunity of carefully describing 

 and figuring the bones, some measurements have been attempted. 

 Such features have been selected as would be comparable with 

 those of other species of gigantic tortoises rendered by Giinther. 

 As already intimated, two specimens are available, namely a larger 

 female (A) and a smaller male (D). It is necessary to mention 

 that, as both the skeletons are articulated, some of the measure- 

 ments are approximate only : —
