In 1866 I had some forty living specimens of our common Spotted Turtle, ranging all the way from those just out of the egg to ones of very advanced age. Even at the present time I have a very beautiful Spotted Turtle specimen of this species—a female— which I have recently photographed, and a reproduction of which illustrates the present article.
