This is sometimes expressed by different signs to distinguish the sex
of animals, when the difference in appearance allows of such varied
portraiture. An example is in the signs for the male and female
buffalo, given by the Prince of Wied. The former is, "Place the
tightly closed hands on both sides of the head, with the fingers
forward;" the latter is, "Curve the two forefingers, place them on
the sides of the head and move them several times." The short stubby
horns of the bull appear to be indicated, and the cow's ears are seen
moving, not being covered by the bull's shock mane. Tribes in which
the hair of the women is differently arranged from that of men often
denote their females by corresponding gesture. In many cases the sex
of animals is indicated by the addition of a generic sign for male or
female.
