Myxophyceae of cosmopolitan habits. In sparing amounts an undeterminable Chara 
appeared. Finally, four desmids were found in considerable numbers. 11 One of 
these Dr. Taylor is describing as new. He remarks that "it should be observed 
that these species of desmids (which are, as a group, intolerant of salt) showed 
rather weak surface markings and considerable irregularity, so that perhaps they 
were adapted to slightly brackish conditions. This is supported by the presence 
of the only phanerogam associate, Najas marin a, which is normally an inhabitant 
of brackish water. 11 
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 Havy 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. 
There were so many sharks at Clipperton that they utterly ruined the 
fishing. Not only did they destroy the few fish that were hooked, but they 
usually destroyed the tackle as soon as it was put into the water. Closer in 
toward shore the President observed a considerable number of blue trigger fish 
schooling about at the surface and, desirous of knowing more about them and ob- 
tain! ng a few specimens of them for the Museum, he tried baiting a trout hook 
with a tiny strip of fish skin. It was just the thing, for three of them were 
caught in short order. These beautifully colored trigger fish, Melieht hys 
radula . occur also in the East Indies and are found in Hawaii and at Socorro and 
Clarion Islands, as well. The President, who at all times was as much interested 
in the bottom and reef species as in the game fish, got another of these blue 
trigger fish at Cocos Island.
