Sterxum. — The most interesting portion of the skeleton. It consists of five distinct bones 

 (sternebrae), which diminish in length from the first to the last, and increase in thickness in nearly 

 the same proportion. 



First Sternebra. — The most perfect of the five : it presents the length of 10.6, by a width 

 of 6.3 ; in comparison with these measurements, its depth cannot be said to be great* 



Second Sternebra. — It is of an irregular rectangular figure, — 



In length 6.3 



In width ................. 4.3 



Thickness of the anterior margin . . . . . . . . . . . 1.9 



The body of this bone is rather thinner in the middle than the first, and the form of the keel 

 more distinct on its inferior margin, with irregular depressions on the lateral margins for the 

 cartilages of the second and third ribs. 



* Like that of the Mastodon Giganteus, it may be likened in form to the ploughshare, and corresponds in description 

 to that given on page 30. But the sternum, as a whole, is more perfect. — Author's Note.
