ANISORADSIA MAWLEI, I. and M., subspecies SAUNDERSI, Ashby. 
(Trans. Roy. Soc. S. Austr., vol. xlii., 1918.)

gave a brief description of a new chiton, giving it the name 
of saundersi, and placing it, with some doubt, as a subspecies of 
Anisoradsia mawlei, I and M. Since my return from America 
my friend Mr. W. L. May has supplied me with some splendid 
the type to Mr. Iredale for his comments, as in 1917 I sent 
him a second specimen collected at the same time and place.
