HILL: GEOLOGY OF JAMAICA. 229 
remains of some pillars, so the coral is pretty surely a Stylocenia. The 
septa are apparently in two cycles of cight septa each, eight large septa, 
and eight small, making a total of sixteen. The walls are rather thin, 
.9 to .5 mm. thick. The calices are irregularly polygonal in outline, 
their diameters usually 2 mm. The calices are smaller than the 
measurements given by Edwards and Haime;! they give 2.5 mm. for 
Stylocenia emarciata, The detailed characters of the pillars and of the 
upper surface of the wall cannot be made out. Later in the present 
paper I describe this as Stylocenia duerdent. 
In a later paper, Duncan describes another species, Colwmnastrea 
eyert, sp. nov., from “ Eocene shales, Jamaica.” 
As he published a fair 
deseription and figures of this species, no further remarks are needed. 
In this same paper, in the table of West Indian fossil corals,? Paracyathus 
crassus, Edwards and Haime, is cited from “Jamaica, Eocene.” The 
original specimen %s indeterminable, and needs no consideration. 
Duncan's last contribution to West Indian paleontology is “On the 
Older Tertiary Formations of the West Indian Islands."* 
This paper 
deals with a collection of corals, made by Mr. P. T. Cleve on the island of 
St. Bartholomew, and considered by Duncan as of Eocene age. Duncan
