This little sliell seems to l>e very rare in Britisl. Columbia Dr 

 Dawson ilre.lo:ed two dead specimens in J Fouston-Stewart channel Queen 

 Charlotte Islands ; Dr. Newcombe found u ftw si^ecimens living' at the 

 roots of iMacrocysfis in Clayoquot Sound ; and 1 have a single dead shell, 

 which I picked up on the beach at Victoria.

The Chitons of the PaciHc coast are numerous and very interesting 

 and as a consequence they have received a good deal of attention at the 

 hands of conchologists. Drs. Carpenter. Dall. and Pilsbry, have all 

 written at length upon this subject and it will be sutftcient for present 

 purposes for me to refer to their papers' and to limit my own remarks 

 to a simple record of the distribution of the various species within our 

 province . 



1 may say that while there are still some of the smaller forms about 

 which we are in doubt the names of the majority of our Chitons are, I 

 believe, correctly determined . Numerous specimens of all but three of 

 the species admitted to this list are in my own collection.

This species is of common occurrence under stones between tides and 

 it has also been dredged not unfrequently nea^- Victoria and in Departure 

 Eay, attached to stones and broken pieces of shell. It was also obtained 

 in this way by Dr. Djiwson at Alert Bay and Freshwater Bay. 



L. cuncellatus resembles, very nearly, several other siDecies of the 

 same genus, and I am not quite sure that all our Vancouver specimens 

 really belong to the present species.

The synonymy of our s])ecies will lj(> found exhaustively treated in the two last 

 named works.
