interior flat, which is surrounded by low limestone hills. These rise not over 100 feet above the central plateau which is covered with grass, scrub, weeds, Pandanus, ferns, etc. Around the grassy area is a transitional zone which, while still covered by ferns and grass supports small trees and nu- erous groves of coconuts. The forests on the limestone slopes are not as thick as usual, but the slopes are quite up to form in roughness of surface. Large areas have been cleared and the little pockets of soil between the rough limestone rocks are planted to yams, sweet potatoes, taro, bananas, papaias, etc. The highest elevation is at the S.E. corner of the plateau, 310 feet, the hill being called Rukuruku by the natives. A more prominent hill at the S.W. corner is nearly as high and named Thaumavuta. Insects fairly plentiful, especially the gray weevil which is very abundant, especially on the yellow flowered composite. The greenish are ab- sent. Large fuscous and yellow spiders suck the body juices from unfortunate grasshoppers and moths which become entangled in its sticky orange colored web. Saw one large grasshopper which had just been entangled being attacked by the spider. It takes a firm hold with its mandibles across the labiam. Butterflies of several spp. numerous. Lizards abundant, both the olive and brown striped skrank and an all light gray-green sp., the latter less abundant. The natives report snakes as abundant, both black and gray species. Good country for them but saw none. Small area of low tuft grass at S.W. end with light brown leafhoppers, black bugs, pale slender brown bugs, pictured winged flies, etc. The white butterfly with black and yellow markings plentiful in this locality. Few mosquitoes, probably scarce because of the absence of water. Only one or two little water holes on the plateau. Houseflies are plentiful and sticky.
