the plants for insects. Among the more conspicuous noted:-the white butter- fly with black and yellow markings; small yellow flies (very abundant); small black flies; small green dolichopodid flies; small fuscous ants; a grayish loafhoppers; a small gray beetle (weovil) etc. This island is especially interesting because it forms a transition be- tween the nearly bare rocks like Latei Viti, Latei Tonga, and Bacon Island and the small islets like Vanua Masi on which trees have become well estab- lished, dirt and sand accumulated and coconut palms taken root. Wish I could have been on it longer. Saw no lizards or snakes, but the former or both may occur. The surface was rough and the trees formed such a dense shrub-like covering that one could neither get about readily nor see far on the surface. Returned to the schooner after another mile pull in a choppy sea at 4 P. M. Down along the west side of Tuvuthá, which lies directly south of Vokai, about 5 1/2 miles distant and anchored at 5:30 in the curve of the reef near the south end, in 13 fathoms. Tuvuthá is the highest elevated coral limestone island I have yet seen in Lau. The mountains rise rather steeply, in places in sheer cliffs up to 800 feet. There are three such masses. The peak at the north is the highest and most conspicuous, with an elevation reported to be 800 feet. Near the middle of the west side is a high ridge nearly as high (50 to 100 foot lower) but of greater bulk. Just south of this there is a pass. The south end again is high, about the same elevation as the central part (700 to 750 foot), but of even greater mass.. The slopes of the southern peak, and to a less conspicuous degree the other two, rise in terrace-like steps. Along the beach from a low ridge 100 to 150 feet high rises steeply from the undercut shelf. There are a few small sand beaches along this side, backed by little patches of coconut palms. The slopes, except the bare cliffs, are heavily wooded and
