Followed a very good trail clear to the west end of the island. The central portion south of the northern ridge and west of the deep bay is flat, with one of the most extensive groves of coconuts yet see in Lau. The grove is more than half a mile wide and fully a mile long. The west end of the island is undulating and smooth underfoot, with a very typical lowland forest. Saw no new trees in fruit or flower. Collected a lot of landshells both in the central flat and western forest, they being very abundant on the leaves of shrubs and small trees. Beneath the coconut groves they were mainly on the leaves of Piper insecti- fugum(?) which with the red pepper and shrub No. 382 makes up the bulk of the undergrowth. Also collected quite a number of insect specimens, especially on dry leaves, under bark and sweeping the shrubs. The trail ends at the middle of the west end bay, in a sand beach, flanked by a small coconut grove. A small wooded islet lies partly across the bay, off the S. W. point. The bay is shallow with numerous coral heads and patches of reef. Walked along the undercut shelf (it being low tide) to the N.W. point of the island. Caught a black and white banded water snake among the rocks. Caught one of the brown and gray Noctuid moths which hide in crevices under the over- hanging roof of the beach ledge here as elsewhere in the group so far. Collected a variety of specimens - yellow-brown coccinellids, payllids (?) small flies, etc. from the leaves of a milo tree badly infected with scale and aphids. Caught some Lycinids, a white moth, and some Sarcophagids on the grass covered sand beach while eating lunch. Returned over the same trail, collecting more insects and landshells. A small marsh, W. by S. from the village, is filled with tree ferns (No. 471). Nearer the bay is quite a little patch of a Sisal-like plant (No. 472), which I found in flower.
