Abstract
(From the Introduction)
Although scientists have been interested in the spiracle for a number of years, very little investigation has been done. In this study the writer shall endeavor to describe the structures and functions of the spiracle in the Cyclostomes, Elasmobranchs and Pisces as well as show the continuous development of any structure as to its function in the animals studied.
