13/16.
I spotted all the Shemales, including the really cute one 3rd down from the top in the left column - not only because I recognize the photo from other tests, but because the large hand in the picture gives it away.
But I mistook a few of the women for Shemales as well. 2d row from the bottom was a guess - I knew the one on the right was Female and the one on the left was too close to call (I thought the jaw was a bit wide and the mouth might be enhanced).
Also 3rd one up form the bottom on the right side, I thought the head was too big to be a woman.
