loped in matting, the reddish hair was adhering. 



I collected samples of all the shells in the strata, and submitted 

 them to Mr. H. B. Preston for examination, and he agrees with me 

 that they were not deposited with a raised beach, but were the refuse 

 forming a "kitchen midden." I append Mr. Preston's report : — 



" I. — A Fissuiella bears traces of having been held over a fire, as 

 the shell is cracked as though by the action of intense heat. 



2. — Another specimen oi Fissure] la is so fresh internally as to give 

 the impression that it has in no way been 'beacli-rolled.' 



3. — The Purpura has probably been split open, as though to 

 obtain the animal whole. 



4. — All are probably edible kinds, and easily obtainable within 

 tide-marks.'' 



These remarks I can corroborate, and supplement as follows: — 



5. — All these species are now collected by the people for food 

 from the rocks. 



6. — They are all rock species, which when dead would quickly be 

 smashed to pieces by the tremendous surf always running. 



y. — There are no small specimens among them, the big ones 

 being naturally selected for food. 



8. — There are no small species among them, though an abundance 

 of small species is found now on the rocks with the large ones, and 

 would be mingled with the large ones if naturally deposited. 



Mr. H. B. Preston, to whom I have submitted all the shells col- 

 lected during the voyage, has kindly sent me the following notes.
