h. The Pelvic Girdle (Text-fig. 27). 



The pelvis has the somewhat narrow form characteristic of Ruminants. The 

 ilium is widely expanded anteriorly, but narrows much in front of the acetabulum. 

 The pubis is a small bone. There is a long symphysis ischii. The ischial tuberosities 

 are very prominent, as is usual in Ruminants. The obturator foramen is oval and of 

 moderate size.
