Diagram to show the arrangement of the hair upon the frontal and basinasal regions of the Okapi's head. 

 The free ends of the hairs are represented b)' the points of the arrows, a and c are natural bald spots 

 overlj'ing the apices of the boss or tumescence of the right and left frontal bones, i is a bare spot, 

 probably due to abrasion. The tuft of hair below c is well-marked, but is absent on the opposite side 

 of the head. The whorl marked d corresponds in position with the slightly tumescent base of the 

 nasal bones. The unlettered whorl, near the middle of the figure, possibly owes its position to the 

 left of the mid-line to unequal stretching of the skin by the taxidermist. The study of the hair- 

 whorls on the head of various Mammalia may yield important data for systematists, but has not yet been 

 methodically carried out.
