Fig. 4. — Ventral view of left innominate bone (N.H. 197), from the Newhall Caves, Edenvale, 

 Co. Clare, preserved in the National Museum, Dublin (i nat. size), a, ilium; b, ischium; c, pubis; d, 

 acetabulum ; e, obturator foramen. 



g. The Posterior Limb. 

 This, as noted by Graudry and Boule, tends to be somewhat shorter in propor- 

 tion to the size of the animal in U. spelseus than in the bears of the arctos type.
