Wrapped up alcoholic specimens. Ashore on Naiabo island at 1:30 P.M. Naiabo islet is ovate in shape, about 150 by 250 feet and 25 to 30 feet high to the tree tops. It is of limestone, with a sand and broken coral beach on the east and north. Off the north point there is a very narrow wind- ing passage through the surrounding reef which makes the islet accessible to row boats at moderate or high tide. The west and south beaches are of coral rock, with patches of Portulaca, Sesuvium (?), and Boerhaavia. The center of the islet is occupied by an open "forest" of stunted buka trees, 8 to 15 feet high and abruptly truncated on top by the wind. In these trees is a rookery of boobies and perhaps terns. Caught a number (10) of geckos in a hollow "buka" tree and several small greenish-olive-brown lizards under rocks on the beach. Hermit crabs, both the large red-legged and a smaller cream colored species were abundant. Insects consisted of red ants and black ants; a small pale yellowish fly, a slender black Nemocera fly, a robust Sarcophagid; the common brown and white moth, on Portulaca, etc., a small white moth, a bright colored micro; a pale brown cricket on the buka leaves; the larvae of a beetle, possibly a Tenebrionid, under a dead Frigate bird; a very small brown mite under rocks; a purplish sow- bug, and brown to gray spiders very abundant on buka trees and a large brown spider occasional about coral rocks. Returned to the schooner at 3:30. Sun came out for a minute and I took:- Roll 60:2. Naiabo islet from W.N.W. (11514) Using the engine we were able to anchor off the N.W. bay of Navutu Iloma island in the Yangasa Cluster before sundown (at about 5:30 P.M.). This cluster of four islands within a nearly closed reef is inhabited, but is "farmed" by the people of Mothe Island which lies about 17 miles to the north.
