On the Change of Colour in the Eyes of an Attis Spider

Article metrics


ON Saturday, September 5, I found a small spider with light green, transparent legs and brown body with silver flutings. I bottled it quickly, and hurried up to my friend Mr. Strickland, and on examining it there under a magnifying glass observed a frequent change of colour in its eyes. I took it home, and on examining it for about six hours consecutively found it to have the faculty of changing the colour of its eyes at its own free will. In an instant it changed the honey-coloured eyes into shining black. While it changes the eyes, a bright dot or streak appears and vanishes all at once.
