lands to the coast, the Montpelier beds are magnificently displayed in 
the road cuttings. Here the road descends through a thousand feet of 
the white limestone, the lower half of which consists of the Montpelier 
beds. 
The hill country back of Port Maria is largely made up of the Mont- 
pelier beds, which are also well exposed near Dover, where Globigerin® 
chalks with flints make up the beds. 
At the bluffs from one to two miles east of Buff Bay, which are more 
fully described under the head of the Bowden beds (see Figure 23 and 
Plate XXVII.), the Montpelier flint beds are seen beneath the Buff Bay 
formation. They are here exposed at and just east of the tunnel. This 
section shows gradation upward into chalks without flints, and reveals 
clearly that the Montpelier beds are stratigraphically below the Bowden 
Oligocene. Three miles east of St. Margaret Bay, at a high bluff

there is a good exposure of the Montpelier flint beds. The collections 
of the chalky limestone in which these flints were embedded consist of 
Globigerine. The beds here have a strong south dip. From the 
locality above mentioned to near Port Antonio, the flint bearing beds 
frequently outerop in the bluffs and are capped by the Bowden beds. 
The high bluffs backing the bay about one mile west of Port Antonio 
afford a good oxposure of beds which apparently represent a phase of 
the Cambridge beds grading up into the Montpelier. Here the bluff 
is made up entirely of white limestones of varying texturo and greatly 
disturbed. The lowest rock exposed is very hard limestone, sub- 
erystalline in texture in some places, and in others showing thin lamellae 
of blue-black clays suggestive of the Cambridge beds, From the lower 
and harder limestones casts of several of the molluscan species of the 
Cambridge beds were collected, including a gigantic Nerinwa and a 
Lucina. These fossils, together with the impurities of clay shale, sug- 
gost that this portion of the beds belongs to the Cambridge formation. 
Just above the foregoing strata there is a soft pulverulent bed of gran- 
ular texture which is composed entirely of Cambridge Miliolide. The
