AMONG A FEW SPECIES OF THE BOVINE FAMILY. 239 
in their length, seem to be referable more to the basilar than to the extreme of the cra- 
nium. On the other hand, the length of the pelvie bones does correspond with the 
cranial extreme. 
In its transverse dimensions the enclosure of the pelvic cavity has no marked identity 
with the transverses of the cranium. The ischial transverse has some relation to the 
coronal, or to the extreme, lengths of the head. At the same time, the ischial transverse 
dimension is very nearly the same as the acetabular, the slight excess of the ischial over 
the acetabular in the males being reversed in the females. In the young Gambian Buf- 
falo the acetabular development had been more rapid than the ischial. 
There is a considerable diversity in length of limb among Bovines, as much in regard 
to the atlantal limbs compared with the sacral,,as to the separate bones of the limbs com- 
pared with each other. Except in the male Bantiger and the Gambian Buffalo, the hu- 
merus is in a small degree shorter than the radius; while there is more excess of length 
_ in the femur over the tibia. The male and the female Bantiger show a difference almost 
beyond what is specific. In Bovines generally the atlantal extremities are curtailed of 
the proportion of the longer sacral bones by from a third to a half of the basilar length of 
the cranium.
