R. Clapp - 1964 Nov. 1. Kwadjalein Atoll. I took two pictures of the large purple form of hermit crab and one of an ant gallery in a Messerschmidtia tree. These latter ants were large and reddish and according to the entomologist are a large carpenter ant, Camponotus. The entomologist also noted that his traps were turning up good numbers of mosquitoes and crane flies. On the way back to the Shearwater, 3 Black naped Terns were seen feeding low over the lagoon waters. In the evening I spent much of my time working over the fishes and identifying as many as I could.
