remains of some pillars, so the coral is pretty surely a SfyJoccenia. The 

 septa are apparently in two cycles of eight septa each, eight large septa, 

 and eight small, making a total of sixteen. The walls are rather thin, 

 .3 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 

 Styloccenia emarciata. The detailed characters of the pillars and of the 

 upper surface of the wall cannot he made out. Later in the present 

 paper I describe this as Styloccenia duerdeni. 



In a later paper,^ Duncan describes another species, Columnastrcea 

 eyeri, sp. nov., from "Eocene shales, Jamaica." As he published a fair 

 description and figures of this species, no further remarks are needed. 

 In this same paper, in the table of West Indian fossil corvds,^ Paracyathus 

 crassus, Edwards and Haime, is cited from "Jamaica, Eocene." The 

 original specimen is 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 

 lists or describes the following species : — 



Flabellum appendiculatum, Brong- Astroccenia multigranosa, Reuss. 



niart sp. A. ramosa, Sowerby sp. var. 1 and 2. 



Stylophora compressa, sp. nov. A. d'achiardii, sp. nov.
