r = radial, t = tangential diameter. 



The ribs from the 4'^ — 10*'' (incl.) diminish in breadths above their 

 lower ends to increase again near the junction of the middle and 

 upper thirds. 



Above and internal to the angles the radial breadths so far as 

 the 10'^ predominate. Behind the tenth the necks are rounded. 



The posterior edges are not sharp.

The cartilages of the 2"^ 3"*, 4"» and ò"» ribs articulate. 



The first rib is thinned along the middle of its length. 



The second at the outer and posterior. 



The third is thin in front and is thinned at the expense of its 



outer as well as its inner surface.
