CORRESPONDENCE.— Spiders with changeable eyes. 

 Sir, — The other day while I was Hstening to the band in the 

 Victoria Park, Colombo, another species of altis spider appeared 

 on the bench where 1 was seated, and proved to be one with 

 changeable eyes."^ It w^as safely bagged, arid I have been able 

 to put it into a small test-tube, and see, under a pretty strong 

 lens, exactly the mechanism by which the colour of the eye is 

 changed (in this case from black to russet red). It is so simple 

 that one is surprised that arachnologists should have been so 

 led astray, as to fancy it might depend upon the play of light. 

 The eyes of the spider consist of transparent chitin (?), and 

 behind this is a globe, or possibly a disc. I am practically 

 certain that it is a globe, half the globe is russet red, the other 

 half is black, and the spider has the faculty of revolving it. 

 Sometimes it revolves one eye, and changes its colour, sometimes 

 only the other, sometimes both. And that is all ! — Yours etc., 

 — W. W. Strickland, Colombo, Ceylon.
