they washed upon the shore. Suddenly a larger wave than those 
which I had been accustomed to see, rushed forward and with a 
mighty splash, broke within a few feet of us. The water and foam 
erept so quickly in our direction that my shoes were soon filled with 
the cold sea-water. With a quick spring, I was upon my feet and 
hurrying from the scene of the unfortunate event. When returning 
to the spot where we had left a stick half buried in the sand, I came 
across unexpectedly two valves of Semele rubrolineata and a most 
delicate and perfect fresh-looking specimen of Mytilimeria Nuttalli 
Conr. 
How truly patriotic were the little shells to come and cast them- 
selves at my very feet, upon this eventful day. The rose colored 
radiations on the Semele were beautiful and looked like many sky- 
rockets going heavenward.

I have not gone carefully over the species collected—doubtless 
many others might be included in this list—but the above will serve 
to show the rich molluscan fauna of this certainly delightful penin- 
sula. The territory worked over by me cannot be more than four 
miles square. The specimens collected already number many thou- 
sands and the rate at which they are being gathered, who knows but
