1 Since the above was written I have received a specimen of I. hexagonus var. 

 cookei Pack, through the kindness of Dr. E. M. Walker to whom it was sent by Dr. 

 P. E. Rochon, Clarence Creek, Ont. It was found fixed in the skin of a woman 

 over the right breast where it had been for several months. At first she thought it 

 was a wart on account of its small size when first noticed. It eventually became de- 

 tached when full grown and engorged and was then noticed by the woman, for the 

 first time, to be alive.
