fragments of coral, a few pebbles of quartz and of some basic volcanic 
crock. The two small chains of hills running along the entire length 
oof the island, referred to by D’ Albertis, are formed by the outcrop 
cof some of the beds of this series which are better able to resist 
idenudation. 
(£) is the remains of a raised gravelly beach, the base of which 
is 4 or 5 feet above high water mark. The gravel is of a leaden-grey 
"color, and is crowded with fossils, a collection of which I made, but 
;as my native carriers did apparently not appreciate geological speci- 
mens, these, along with some other valuable collections, disappeared. 
(c) is a basaltic lava seen on the beach ; this lava appears to 
emanate from one of the high hills which stand out prominently 
between the two escarpments of the sedimentary rocks. I had no 
other opportunity of examining the structure of the island. 
At the village of Delena, on the south side of Hall Sound, I 
examined a section in the cliff’s to the north. A sketch of this is 
given below : —

In this section — 
(i) consists of buff shale, sandstone and conglomerate dipping 
north-east, separated by a fault (/) from (2) buff-colored clay shales 
containing fossils. Proceeding northwards along the coast, the beds 
become almost vertical, and another fault (/) divides them from 
(3) a mass of thinly bedded limestone with bands of clayey shales. 
These limestones yielded the following fossils : — 
< 
Gasteropoda. Conus Turrit ella . 
Lamellibranchiata. Cardita. 
Marginclla . (?) 
Pecten. 
Pectunculus . (?) 
and Venus. 
In the upper portion the clay shales predominate ; these also 
yielded a suite of, as yet, unnamed fossils.
