THE NAUTILUS. 67 
Calliostoma supragranosum Cpr.—Detected in kelp holdfasts. 
Cyanoplax hartwegii.—Perhaps our commonest chiton, on 
rocks near high-water mark, strangely omitted from Smith’s list. 
Columbella fuscata.—One specimen was found living years ago, 
but no doubt estray from southern waters as well as a single 
well-developed living specimen.

The above are some of the shells omitted from the lists re- 
ferred to that I have noted on the beach, quite a number of 
them in kelp holdfasts washed ashore. 
A considerable number of minute shells yet undetermined 
will add considerably to the list, besides several chitons and 
larger shells that are being studied.
