November 18, 1863. — Professor A. C. Ramsay, President, 

 in the Chair. 

 The following communications were read : — 



1. "On the Fossil Corals of the West Indies."— Part II. By 

 P. Martin Duncan, M.B., F.G.S. 



This communication embodied the second part of the author's 

 researches on the Fossil Corals of the West Indies (the first part 

 having been read before the Society last session), and consisted 

 chiefly of a description of Corals returned to the Society's Museum 

 by Mr. Lonsdale soon after the reading of the first part. Some 

 portions of these descriptions were stated to have been taken from 

 an unpublished MS. by Mr. Lonsdale, now in the Society's Library, 

 with the permission of that gentleman, such quotations having been 

 duly indicated. 



The predominance of simple fossil Corals in San Domingo, and 

 their complete absence in Antigua, were pointed out; and it was 

 remarked that the same kind of distribution occurs at the present 

 day, pedunculated compound forms being very common around the 

 northern Antilles, but rare around the north-eastern, although the 

 corals are mostly of different genera from those found in the fossil 

 state. The author concluded with some remarks on the physical 

 conditions of the Miocene period in the West Indies, observing that 

 the Nivaje shales and associated deposits are the remains of an 

 ancient barrier-reef, and giving an analytical table of the affinities 

 of the species, in which it was shown that the Pacific and East 

 Indian element greatly preponderated. 



2. " Notes to accompany some Fossils from Japan." By Captain 

 Bullock. Communicated by Sir R. I. Murchison, K.C.B., F.R.S., 

 F.G.S. 



There having been no geologist attached to the late surveying- 

 expedition of H.M.S. "Dove," the Commander of that vessel en- 

 deavoured to repair the consequent loss to science, so far as his 

 professional duties would allow, by collecting fossils, and by record- 

 ing their localities and the circumstances under which they were 

 found. The specimens were presented to the Geological Society 

 through Sir R. I. Murchison ; and this paper contained all the infor- 

 mation, respecting their occurrence, which Captain Bullock had been 

 enabled to obtain. 



3. " On some Miocene Mollusca from Mount Sela, in the Island 

 of Java." By H. M. Jenkins, Esq., F.G.S. With a Description 

 of a new Coral from the same locality, and a Note on the Scindian 

 fossil Corals; by P. Martin Duncan, M.B., F.G.S. 



A short notice of the scanty literature of Javan Geology having 

 been given, the author described briefly the geological and physical 

 features of the Mount- Sela district, and made some general ob- 

 servations on, and gave descriptions of, the fossils which were the 

 subject of the paper, and which had been sent to England by 

 M. Corn, de Groot.
