74 THE NAUTILUS. 



the rocks, but I think he is a good-natured inoffensive big fellow and 

 does not eat up his little neighbors and companions. We have a 

 Barleeia that is said to be a lover of the Haliotis, but I have found 

 but very few of them, the Odostontia being by far the most plentiful. 



When it gets dull on the farm and we want a day's outing, Mrs. 

 Oldroyd and myself go to White's Point for a day's collecting. We 

 do not have to wait for a low tide or go near the water, but make us 

 a comfortable seat at one of these large piles of shells and pick off 

 the little shells till we get tired. We find out where the abalone 

 comes from so as to get the locality of the small shells. 



The following list is what we got in a few days' collecting, but 

 this is nowhere near the limit to what might be found. They were 

 determined from others in our collection, which were determined at 

 Washington through the kindness of Doctors Dall and Bartsch :
