The measurement of D for the first rib was taken at the tubercle 

 the others at the angles. The radial breadth is taken in the first 9 

 in the others the tangential. The antero posterior flattening is marked 

 in the anterior ribs and the upper thirds of the first nine are very 

 strong. Below the 9*"^ rounded. 



The Rhinocerus. 



Thorax 120 cm. 



First rib 75 mm. in front, and diminishes to the angle which is 

 40 mm. 2"*^ 35 mm. at the lower end and 35 mm. at the middle. 

 3'* 40 mm. above. 4*^ 35 mm. below, 35 mm. at the middle and 

 50 mm. at the angle. 5*^^ 50 mm., 40 and 35 respectively (radial). 

 6* 40, 35, 30. The sixth is nearly square on section. The seventh 

 = 40, 27, 30 and square section. 8*^ 35, 30, 30 tangential measure- 

 ments. 9*1^ 30, 35, 28. lO''^ 25, 35, 25. ll*"^ 25 t, 37 t, 25 t all tan- 

 gential. 12*^ 23, 37, 25. The second measurement is made at the 

 middle in the last three ribs. 13^^^ 19, 35, 25. 14*^^ 15, 36, 30. W^ 15, 

 34, 25. 16*^ 2Ö, 37, 25. 17»^ 20, 30, 25. 



The posterior edges of the lower ten are sharp. 



The depth of the thorax (antero posterior) in the lateral line is 

 140 cm. 



The Elephant. 



First broader below than above second uniformly broad and with 

 a sharp anterior border, surface convex from before back. 



3rd J.ÌI3 Ygj.y thick strong and broad, lower end compressed from 

 within out middle piece thick especially along the middle. 



The S«"«!, 4*^ and 5"^ ribs are of nearly uniform breadth so far as 

 the angles, the thickness is greatest along the middle a little above 

 the lower ends.
