THE EYES OF THE BLIND VERTEBRATES OF NORTH AMERICA. 201 



XVIII. BIBLIOGRAPHY. 



A list of the papers dealing with the eyes in blind vertebrates is given in my first paper (Eigenmann, 

 '99, p. 611). I add here the papers published since that time, together with those dealing with the general prob- 

 lem under consideration and not referred to in my earlier papers.
