R.Clapp 1964 Nov. 1 - Kwadjalein Atoll. Spent the morning skinning birds with Larry in the lab. Both Sooty Terns skinned were very fat. Huber collected more fish for the turtles. In the afternoon we all (with the exception of Ken Amerman and George Wislocki) went over to Carlson Island to poison fish. While the rest went out to the edge of the reef with the rubber raft, I scouted the lagoon shore of the island while the entomologist, Dave Perkins collected insects. I collected a fair series of hermit crabs. There seemed to be three varieties (or age groups) commonly found) One, rathers, large, hairy, and red appears to be the same form that is found in the Phoenix Islands. Another, smaller is red and white but may be a young form of the red hermit crab. Another small form appeared to be gray or brown all over. Three examples of a fourth variety were seen. These are generally larger than the red hermit crabs, are a dull color, and are considerably less hairy. In addition their largest claw seems more well developed than is true of the red form. This species is considerably more active than the red form and it may be for this reason that their shells seem to be in poorer condition. When handled, unlike the red form, they struggle actively and vigorously to get away and retreat but seldom into their shells (all of which appeared to be Turbo) In addition , they seem to prefer heavier cover, all those examples seen having been seen either under shady coconuts, or in the dense foliage of the beach morning glory. As a whole Turbo shells seem relatively scarce around this island. Nereis ? or related shells are frequently utilized, and augurs or mitres scombrids ? sp ? and numerous other forms are utilized as well. While traversing the interior of the island I saw two rats, but they were not clearly enough seen so that I could be sure of the specific identification. Probably exulans One was missing a tail.
