no well defined forms, — although a minute fragment or two in some of 

 the collections are very much like Radiol arian tests. Nowhere on the 

 island have rocks been found made up nearly entirely of these forms 

 such as occur in Barbados, Haiti, and near Baracoa, Eastern Cuba. 

 W. B. Hill has stated^ that "one or two Radiolarians can be seen in 

 outline in a rock in which Globigerinse are conspicuously abundant," 

 from Hanover Parish, — where the Montpelier beds occur. 



The lower White Limestones of the Oceanic Series are composed of 

 chalk making Foraminifera, deposited in deeper waters than the preced- 

 ing beds, and of these there are several distinct horizons each composed 

 of a different character or association of Foraminifera. 



Globigerinae appear in great number, composing the chalky strata of 

 the Montpelier beds on the north coast near St. Margaret's, the hill at 

 Montpelier hotel, and the rocks underlying the northern side of the 

 plain back of Savanna-la-Mar, AVestmoreland. 



W. B. Hill ^ has also described a specimen of white limestone from 

 Hanover County, which he asserts is an '' oceanic deposit," in which 

 " thick-shelled Globigerinse similar to those of the Barbadian rocks " 

 are very abundant. Jukes-Browne and Harrison ^ have said that Colonel 

 Fielden, who sent this specimen from Hanover, reported that flints were 

 abundant in the formation. I do not Jiesitate from our acquaintance 

 with this region to state that this specimen is from the Montpelier 

 formation. 



Orbitoides and Nummulinse, which have already been noted as occur- 

 ring in the Cambridge beds, continue into the Montpelier, as Bagg's 

 studies of our specimens show, and from the specimens described by 

 T. Rupert Jones the stratigraphic position of which we have been able 

 to identify, thanks to his having given localities of material studied by 

 him from Jamaica. 



Bagg reports the following Foraminifera in our collection, from the 

 Montpelier Formation. 



Flints from Montpelier Hill (No. 75) : — Orbitoides dispansus, Sower- 

 by ; abundant, Eocene. Orbitoides mantelli, Morton, rare ; uppermost 

 Eocene and lowest Oligocene. Orbitoides papyracea, Boubee, Eocene. 

 Nummulites, probably. 



These flints are Eocene.
