The Double Headed Shot Cays, as approached from the south, present one mass of isolated rocks, islets, and islands without vegetation. Elbow Cay (Plate XXXI.), the largest island of the group, is a splendid specimen of the transformations to which the seolian rocks of the Bahamas have been subjected. The surface of the island is deeply pitted and honeycombed in all directions. Near the edge there are many blow-holes, through which the spray is sent in all directions, and on the north side, where the water is deepest, the action of the northers must have been one of the principal causes of the wearing away of that part of the island. The seolian structure of the rocks of the island could be most plainly seen. At the landing to the south of the lighthouse, as well as in the deep channel for landing stores cut into the rock on the north side, the strati- fication so characteristic of seolian rocks was most distinct. Steaming across the bank towards the Anguila Islands we found the bottom on Salt Cay Bank much like that of the other Bahama Banks, with little animal life but many coralline algse. We dredged a few times on the way, bringing up many fragments of shells and broken Clypeastroids showing the effect of the waves on this shallow plateau. The outlying rocks to the northwest of the Anguila Islands could plainly be seen to. .EOLIAN CLIFFS, SOUTH ANGUILA. be of seolian origin. The islands are comparatively low, the north- ern and southern extremities being somewhat higher than the central mass of the islands. The long stretches of low vertical cliffs forming the western shore of the islands are separated by sand beaches. The hills near the southern extremity on the west shore mark the highest part of the islands. Opposite our anchorage were fine seolian hills fr
