102 Duncan—Miocene Beds of Antigua and Malta. 
localities as Antigua and Malta, and after the Caucasus, Sinde, 
Travancore, San Domingo, Jamaica, and Guadeloupe have been 
proved to contain the same species of coral. It is clear that 
there must have been a freedom from those barriers against the 
diffusion of coral-species which now exist; for, if not, how has 
the West Indian Miocene coral-fauna a greater alliance with 
the recent Oceanic and East Indian coral-faune than with the 
recent Caribbean? At present the West Indian Miocene is 
separated from its correlative strata by great areas where no 
coral lives. 
There is a point of some interest with regard to the anatomy 
of the Styloceenia lobato-rotundata. Michelin’s description and 
drawing, and the generic diagnosis of MM. Edwards and Haime, 
have determined the septa to be smooth and Eusmilian in their 
character. One of the specimens from the Maltese bed has its 
calices beautifully preserved; the septa are distinctly incised and 
faintly dentate. This fact removes the genus from the sub- 
family of Eusmiline, and associates it with the Astreans. It 
is worthy of notice that the closely allied genus Astrocenia has 
recently been proved to have dentate septa, and has been 
classified with the last-named sub-family by M. de Fromentel.* 
The presumed connection between styloid columelle and smooth 
septa has thus been rendered doubtful for the second time.

pD»*. DUNCAN’S researches on the Paleontology of the 
West Indies have so much enhanced the value of any 
fossils found in those islands, that I do not hesitate to make a 
few remarks on some Orbitoides contained in a piece of Anti- 
guan ‘ Chert,’ given many years ago, by Dr. Nugent, to the 
Geological Society, and to which Mr. H. M. Jenkins, Assistant- 
Secretary G.S., some months since directed my attention ; 
and also on some specimens of fossiliferous flint and limestone 
from Jamaica.

bonate of lime,{ and is traversed in all directions by thin, flat,
