st point,which is 966 feet above sea-level, it sends out spurs towardsthe east and the north-east, divided by deep valleys which slopesteeply down to the coast. On the north a ridge extends tothe hill known as Chalky Mount, the northern slopes of whichsink almost precipitously to the Valley of St. Andrews. On thesouth-east and south it slopes somewhat steeply into the valleyof a little brook called Joes River. Another little brook, knownas Tar Hole Gully River, divides a spur, running nearly due eastand capped by two outliers of radiolarian earth, from two con-tiguous spurs running a little north of east, along and partly acrosswhich a fault-line can be traced. On the west it sinks intoanother deep valley known as Dark Hole, which drains northward.Between the valley of Dark Hole and the western part of the JoesRiver valley is a high ridge running south-westward, which, likethe neck of an isthmus, unites Bissex Hill to the central highlands See Quart. Journ. Geol. Soc. vol. li, p. 311.

Vol. 54.) THE GLOBIGEEINA-MAELS, ETC., OF BAEBADOS. 543 of the island near Chimborazo, where the elevation reaches 1100feet. Along this ridge a road is carried from Chimborazo to BissexHill, and thence along the western slope of that hill. A branch ofthis road climbs to the Police Station, which is built a little belowthe summit of the hill, at the offset of an easterly spur. From the main road a branch runs in a north-easterly direc-tion along the face of the southern rise of Bissex Hill, and near thepoint where the roads diverge a fault occurs, which accounts for theexistence of an outlier of Oceanic Beds on Parks Estate at a level ofabout 700 feet, while the base of the same beds in the roadway isseen at about 800 feet. This fault (F. 1 on the accompanying map)has an upthrow on the north side, and the Oceanic Beds seen alongthe road dip locally at a high angle (45°), later at a low one of about5° to the north-west, and extend up to a height of about 865 feet.They are then succeed
