IX. Sterols of Echinoderms
A considerable, instructive body of data has become available during the past decade on the sterols of animals encompassed by this
phylum. Representatives of all its five classes and of the majority of
their orders have been investigated. Their total number and their representation of various climatic and geographic zones are more than
adequate to lend significance to the data so far obtained. Table IX lists
