Cap of open forest on ridge and higher peak behind the "Thumb." Collected "X-bugs" (Mictis profanus var. crux Dallas) on plant No. 572. Over gap and down north valley to pier. To protect his coconuts from possible pest introduction, Mr. Smith prohibits the bringing in of coconuts or baskets made of coconut leaves. He has the following sign posted on the wharf: Na mate ni niu. Moni kila sa tabu sara ni sobu mai e na vanua'oqo no kato se basikete e tali e na drau ni niu se so tale ga na drau ni kau o so. Supper and pleasant evening with Mr. Smith and Mr. Charles Hathaway of Naitamba. Saturday, September 20, 1924. North end Vanua Mbalavu. Underway at 6:30 A.M. from Kanathea; through Ngillangilla passage and anchored in a deep bay on the north end of Vanua Mbalavu, just west of Black- swan point, at 7:45. Both Ngillangilla island (510') and this peninsula are of rough elevated limestone, rising abruptly from the undercut shelf. The open forest which covers the rough slopes is far from "impenetrable," and the slopes themselves are not as rough as those of the Yangasa islets, having pockets and hill sides of oc- casional slight smoothness. We landed at 8 A.M. in a small mangrove choked arm of the bay. Traversed a mile or so of the familiar lowland forest finding one or two new plants and quite a number of cycads. Most of these latter were one to three meters high but two had from 5 to 7 trunks growing out of old butts, 20 cm. in diameter and up to 6 or 7 m. high. Several female trees with fruit. Had previously col- lected foliage at Matuku so took fruit and section of stump. Wild goat manure on cliffs and Correia found large pair of horns which he presented to the museum.
