There is also a simihir connection between the fringing reef off Bololo Point and the barrier north of Na lulu entrance. The south- eastern part of the reef off Ovalau and Moturiki being strictly neither a barrier nor a fringing reef, but a combination of the two, the Xgava and Na lulu entrances forming reef harbors similar to those characteristic of frincino- reefs, indicating how the offshore platform of Ovalau has been eroded and how corals have gradually obtained a footing on the un- derlying volcanic substructui'e, remnants of which are visible at many points of the barrier reef flats. One may judge of the extent of the denudation and erosion which have taken place from the shape of the peaks and bluffs and ridges which give to Ovalau so characteristic a profile when seen from the sea (Plates 33, 34). Compare the sharp peak of Tumuna, the rounded elevations forming the ridge of Xdelai and of Koro Levu, the sugar loaf of Craig, and the bluffs near LEVUKA. The spur which has formed the island of Moturiki is covered by low conical hills, culminating on the eastern summit at Ului Mboa, which is but little higher than the rest of the island. To the westward and northward of Ovalau reach the extensive flats full of patches which connect the west shore of Ovalau with the mainland, and reach on the northwest to Tova and south towards !\Ibau (Plate 7); flats which are formed by the disintegration of the low bluffs, consisting ,of bedded volcanic mud (" soapstone "), which must once have extended eastward close to Ovalau and Moturiki. The patches on the flats are covered with growing corals. VOL. XXXIII. 8.
