72 "ALBATROSS" EASTERN TROPICAL PACIFIC EXPEDITION. 



through which Mount Mokoto can be seen from Port Rikitea (PI. 61). In 

 Plate 58 the northern slope of Mount Duff is seen from our anchorage at 

 Port Rikitea. 



Plates 59 and 60 are two views of Mount Duff seen from the southeast, 

 looking up to the summit from the top of the terrace which runs round the 

 base of Mount Duff, and forms so conspicuous a landmarlc on the east face 

 of the southern part of Manga Reva Island (PL 57). 



The eastern side of the ridge of the northern extension of Manga Reva 

 beyond Port Rikitea is shown in Plate 63, fig. 2- A more detailed view 

 of the eastern slope of Manga Reva north of the village is shown in 

 Plate 62. 



The crest of the ridge of the eastern extremity of Manga Reva and 

 Mata-iutea Point are shown in Plates 70, 71. The western slope of Manga 

 Reva as seen from the pass leading to Kirimiro is shown in Plate 69, fig. 1, 

 as far as Teaua-ua Point, and the crest of the ridge north of the pass, in 

 Plate 69, fig. 2. The outline of the western and northern encircling reef is 

 seen in both the figures of Plate 69. 



On the west face of Manga Reva, nearly opposite the southern termina- 

 tion of the western encircling reef, lies the bay of Gaatavake (PI. 14), in the 

 centre of which is the small island of Kotu-marei (PI. 63). This deep bay is 

 formed by the remnant of the rim of an extinct crater similar to those of 

 the shallower bays to the north. 



On Plate 66 are given views of the eastern inner islands as seen from 

 Manga Reva. Au Kena is seen from the anchorage off Aka-Maru on Plate 

 66, fig. 1. The same island is seen facing the northern side from the anchor- 

 age at Port Rikitea (PI. 66, fig. 2), and the gap between Aka-Maru and Au 

 Kena is shown in Plate 66, fig. S. The encircling reef seen through the gap 

 is not often clearly visible, as the outer islands are quite small. 



The line of the western and northern encircling reefs, as seen from the 

 pass leading to Kirimiro, are shown in Plate 69. In Plates 70 and 71 are 

 shown sueli parts of the northeastern and eastern encircling reefs as are 

 visible from the summit of the central ridge to the east of Taku, the south- 

 ern continuations of which are indistinctly seen in Plate 66, figs. l-S. 



We may now pass to views showing the aspect of the inner islands as seen 

 on our way out from Manga Reva, across the encircling reef and its islets 

 (PI. 14). The inner islands of the southern part of the Gambler Islands as 

 seen after rounding the southeast pass, are shown on Plate 72, fig. 1. Aka-
