Echinochiton dufoei Pojeta et al., 2003 is now known from seven specimens. The new material shows the anterior end and allows for a full reconstruction of the animal. The hollow spines are circumsomal; they were flexible and perhaps moveable in rotary anterior-posterior directions. Possible functions for the hollow spines are discussed. The relationships of E. dufoei to other chitons and to other molluscs and mollusc-like organisms are presented.
