I have seen two specimens of this chiton. It was taken 
by Mr. Klem at Corney Point and named by Mr. Bednall. 
One other very similar J have from St. Francis Island. This 
shell agrees with the description in Pilsbry, Joc. cit., with the 
exception of the colour, which is of a pinkish hue, and the 
posterior valve has not the “six more or less distinct radiating 
ridges,” as described by Smith from Coppinger’s collection. 
Mr. Klem’s specimen has a hairy girdle. The St. Francis 
Island specimen is fleshy.
