after some delay caused by the necessity of finding a practicable landing 
place, through the surf alongside a line that Joe Balicki swam in for us. Our 
time was limited, so it was necessary to collect what we could in short order. 
The thirty-two bird skins obtained here were almost all the result of the good

marksmanship of Lt» Comdr. Kelly and Mr. Michael Reilly. There were four or 
five species in the lot, boobies and terns, adults, specimens in juvenile 
plumage, and some nestling young. 
A number of sand hoppers or amphipods were obtained. At least one 
new species is represented. Among the other crustaceans secured were a pair 
of burrowing shrimp. Call i a nassa . showing well defined color markings in brown 
on their chelae, something not ordinarily expected in subterranean, more or 
less colorless animals. Worms and molluscs, too, were taken from crevices 
in old coral heads. Samples of the common "weeds" which, with a very few 
cocoanut palms, form the principal vegetation of the top of the atoll were 
saved for determination. A generous sample of the algal growth in the central 
lagoon was preserved for the algologist. He has since reported that the 
water in the Clipperton lagoon is surprisingly fresh, and at most only slightly 
bracki3h, when one could well expect the reverse to he true. 
Unfortunately, we did not obtain a sample of the lagoon water, as 
had been planned, for, although the landing was not particularly hazardous 
at the time of our visit, it was none-the-less difficult and had to be made 
by partly swimming through the surf. Our getting ashore on Clipperton is just 
another tribute to the efficiency of the Navy and a further instance of the 
value of their cooperation in scientific exploration. Landing in heavy surf 
is a part of the Navy's routine training, and so they took the Clipperton 
landing in their stride, as it were.
