THE NAUTILUS. 71 
cotton batting, long rubber boots, an immense sun hat, a chisel to 
detach Haliotis shells from the rocks, ete. 
I arrived here at seven in the evening and although the trip down 
was rough, and our little “tub” rocked dreadfully, causing me to 
be sea-sick, it nevertheless did not prevent me from starting right in 
and collecting as soon as my feet rested on terra firma. On that 
evening, I began collecting at seven o’clock and as it was very light 
at that hour, I continued to collect along the beach until eight. I 
am very glad I did so, as it netted me some beach-washed species 
which I have not come across since. 
I selected a week when the early morning small low tides 
occurred. Thus, one morning I devoted to the collection of Hali- 
otis cracherodii, another morning I went in search of Littorina 
planaxis, another for Chlorostoma costatum, Acmzea scabra, Nassa 
mendica, ete. 
During this second week, when no morning low tides have 
occurred, I have gone among the rocks, gathering any and every 
species which was so unfortunate, nay, I should say, fortunate, as to 
be placed within my reach. 
Priene Oregonensis Redf. will be noted as having been collected 
here. Ido not as yet understand how this large and beautiful 
northern shell should be found so far south. It could not have 
drifted into the bay, as it was a fresh, perfect-lipped specimen. 
I may also mention that in a letter recently received from Mrs. 
M. Burton Williamson, of University P. O., Cal., that lady informed 
me that Psammobia rubro-radiata Nutt., is not found north of San 
Pedro Bay. As will be noted, I found one specimen, alive and per- 
fect. It is truly a beautiful shell. The inside of both valves 
resembling delicate porcelain. 
I am exceedingly sorry to think that I have no dredge here with 
me, as I feel positive I could gather at least five times as many 
specimens as I have already collected. 
In the following list, the number of specimens taken is given 
after each name, and will serve to show the relative abundance of 
the species.
