limestone, sub-olliptical in shape about 60 yards long by 30 or 35 yards wide at the widest part, and 50 feet high at S. W. end. The north end is low and rather flat with fair size patches of Portulaca, Sesuvium, mat grass and Boer- havia. In fact small patches of these four plants are to be found in nearly every part of the island, even in pockets on the S.W. cliff face. The Sesuvium grows near the edge while the Portulaca and Boerhaavia is plentiful higher up. Both boobies and terns nesting, with four eggs to half grown chicks. Water snakes, lizards and red legged hermit crabs. Ants, Dermestes vulpinus (?) and a small black beetle under dead boobie. Black Agromyzid fly and small fuscous leafhopper about Portulaca, Boer- havia and Sesuvium. Also a green cranefly about the rocks and Sesuvium. Fuscous and red brown ants, pale mites and two species of weevils, one gray and one smaller and browner about Portulaca roots. and Small brown and white, smaller yellowish gray microlepeplopteras on rock faces. Boobie hippobosicid. Picked up a few Cowries in pools and under ledges on the roof which sur- rounds the islet. This also had the mottled green back crab, blue starfish, and other sea forms on it.
