" The astragalus in the Binocerata considerably resembles that of 

 the Elephant, the bone being, as in that animal, very short, along 

 the axis of the leg and foot. 



" The calcaneum is short, and comparatively moi^e robust than in 

 the Elephant. As in that animal, it is strongly tuberculated below, 

 where, during life, it doubtless supported a thick pad, resting on 

 the ground." 



Bestorations. — " In the restoration of Dinoceras mirahiJe, the re- 

 mains of the type specimen of the species, a fully adult, but not old 

 individual, have been used for the more important parts, and the 

 remaining portions taken from other individuals. This restoration 

 is one-eighth natural size.^ The animal is represented as walking, 

 and the position of the head, and the feet, has been chosen to show, 

 to the best advantage, these portions of the skeleton as they were in 

 life. In this restoration, only those portions are shaded which are 

 represented by actual specimens in the Yale Museum. The parts 

 in outline are wanting, or are so poorly preserved that only their 

 main features can be given with accuracy. 



Fig. 18. — Restoration of Tinoceras ingens, Marsh. One-thirtieth natural size. 



"In the restoration of Tinoceras ingpAis,^ thte animal is represented 

 one-sixth natural size, and standing at rest. The position here 

 chosen shows the massive and majestic form of one of the largest 

 individuals of this remarkable group." A reduced copy of this 

 restoration is given in Fig. 18. 



"In comparing Dinoceras, as here restored, with some of the 

 largest ungulate mammals of the present day, a certain resemblance 

 to the Ehinoceros on the one hand, and to the Elephant on the other,
