     If you do a morphometric analysis on a large sample size, and find
there exactly two morphs in more or less equal numbers, there is a good
chance you are dealing with males and females.  Moreover, the morph called
the "male" has both a more erect frill and a larger "hump" on the nose,
features that might well be excpected in the male of a species.
