Martin and Bennett (1977)have thoroughly described specimens of Daimonelix (devil's corkscrew) which are the helical burrows of Palaeocastor fossor, and a few relevant characteristics of such burrows are summarized here from their work. These helical burrows have an entrance mound and turnaround, a helical shaft, and a ...' The original spelling of this word by E. H. Barbour (1892) was "Daimonelix," which he altered a little later to the familiar "Daemonelix," as used herein. The latter spelling has come into such general and accepted use that it is believed unwise to revert to the original form. Since the word is no longer regarded as a proper generic term,
