At the conclusion of their paper a general statement was given of 
other localities from which raised coral limestones have been described. 
1. Guadaloupe. — This island is volcanic on the western side, and 
has coral reefs on the east, which are found up to a level of 1300 feet. 
2. Antigua. — Volcanic rocks occur on the west and reefs on the 
eastern side up to a height of 300 to 400 feet. 
3. Barbuda. — Coral limestone alone is found, and reaches a height 
of 117 feet. 
4. Jamaica. — Raised reefs are never found above 100 feet, but the 
massive white limestone of the island, which is 2000 feet thick, and 
covers six sevenths of the surface, contains corals, and probably its 
upper part is raised reef. 
On June 21, 1891, Mr. J. J. Lister read a paper before the Geologi- 
cal Society on the Geology of the Tonga or Friendly Islands.1_ No 
analyses of limestones were given, but the paper contained an interest- 
ing account of the structure of the group, including three islands, Eua, 
Vavau, and Tongatabu, visited subsequently by Mr. Alexander Agassiz.? 
Mr. Lister distinguished three kinds of islands. 
(a) Purely volcanic islands. 
(4) Those having a stratified volcanic base, since elevated, and with 
or without limestones. 
(c) Islands entirely of reef origin. 
The islands containing limestones were generally found to be charac- 
terized by definite terraces at different levels. Mr. Lister concluded that 
the islands of the Tonga group have probably grown on banks of volcanic 
origin laid out in shallow water, and that there was no necessity to call 
in the hypothesis of subsidence to account for their formation. 
Dr. G. J. Hinde contributed a short note in 1893 to the Geological 
Society on specimens of raised limestones from New Hebrides. He 
quoted no analyses, but microscopically examined limestones from heights 
of 346, 500, and 1274 feet. They were found to be made up of nulli- 
pores (Lithothamnion), corals, and Foraminifera, and there was no 
evidence of their having had a deep-water origin. 
Among those who accompanied the first expedition to Funafuti was 
Mr. Stanley Gardiner, who has recently published an account of the atoll, 
and observations on the raised reefs of the Fiji Islands* to which Dr.
