NOTICES OF MEMOXES. 
On the Fossil Corals of the West-Indies. By P. Martin 
Duncan, M.B. Lond., F. G. S., &c. — (Quarterly Journal 
of the Geological Society, vol. xxiv., p. 9). 
This is the concluding part of the author’s highly interest- 
ing and valuable contributions on the fossil corals of the 
West-Indies. The first portion of the present paper is 
devoted to a description of the fossil madreporaria found 
by Mr. Eckel in the quarries of St. Croix, Maparima, Tri- 
nidad. Six out of the eighteen species ^numerated by 
Dr. Duncan are new, and he has figured four of them, as 
well as other species from the Antilles. The following are 
the names of the Trinidad species : — 
Heliastrsea endothecata Dune. 
cylindrica Duncan 
* barbadensis Dune. 
■ cavernosa Esper 
■ altissima Dune. 
Brachyphyllia Eckeli Dune. 
irregularis Dune. 
Astrsea pariana Dune. 
Isastrsea confusa Dune, 
Stylophora raristella Defr. 
minuta Dune. 
■ mirabilis Mich. & Duch. 
Stephanocoenia intersepta Esper 
Agaricia agaricites Lam. 
undata Lam. 
Porites Collegniana Mich. 
astroides Lam. 
Alveopora Dsedalsea Blainv. 
The authors views as to the geological position of the 
St. Croix beds is that they are not older than the Nivaje 
shale of Haiti, the Yere beds of Jamaica, and the Chert 
and Marl of Antigua ; and he does not think that there are 
data for establishing a Lower, Middle, and Upper Miocene 
in the Caribean area so as to correspond with the divisions 
of the European Miocene.*

* This conclusion of Dr. Duncan’s, however, may not hold good in 
all respects if the St. Croix beds are shown to be newer than the San 
Fernando and Tamana beds. See “ Proceedings,” antea, p. 154.—=
