Fic. 25. Male and female of the Black Lemur, Madagascar. The 
male only is black, the female being brown with a white ruff. Note 
the opposable thumb and great toe. Though the general shape is 
monkey-like, the foxy faces should be contrasted with those of 
monkeys (Figs. 23 and 24). (From a specimen in the Royal Scottish 
Museum.)
