Humphrey Island: Listed on the hydrographic chart of -Pearl 
and Hermes Reef for 1937 as a sand bar awash at high tide, this 
7 
island has assumed permanent' dimensions in recent years, and has 
been named for Dr. Philip S. Humphrey, Director 
racific Ocean Biological Survey Program. Though less than 200 
feet wide it is presently about 1100 feet long in a north-south 
direction. The long low sand spit at its southern end appears to 
be extending itself southward and in a curve to the west. Three 
small, disconnected sand bars, presently just above high tide level, 
extend the length of the island another 500 feet. Six to eight 
hundred feet vest of the island is another series of sand bars 
which has not quite broken the surface of the water, but obser¬ 
vations i- t& c tnd - for over two years indicate that the area is 
building at present. A central portion of the main 
island, about 400 feet long, rises six to ten feet above sea level, 
and supports a meager growth of Lepturus repens . Bo erhavia diffusa.
