Garden River and the coast south of Morant Point; the Salt Ponds 
hear Yallahs Point; bordering Hunt Bay between Cobre River and 
Apostle’s Battery on the west side of Kingston Harbor ; from Cabiretto 
Point to West Harbor on the east coast of the district of Vere, Claren- 
don Parish; along the south coast of Vere and Manchester from Port- 
land Ridge to Cut River; between Star Cut Bay and Scott Cove ex- 
tending inland adjacent to Black River on the southwest coast of St. 
Elizabeth Parish; from Blueñolds Bay to St. John Point in Savanna- 
la-Mar ; along the truncated west coast of the island between South 
Negril Point in Westmoreland Parish to Orange Bay in Hanover Parish, 
and around Green Island harbor, Hanover Parish. or 
Where these morasses extend a few miles inland up the rivers they 
occupy eroded indentations cut out of the lower Soboruco or Liguanea 
levels, as is especially well shown at Montego Bay, Long Bay, and the 
Mouth of Black, Milk, Cobre, Plantain Garden, and Green Island Rivers. 
In one or two places, as along the north coast between Palmetto Bay 
and Buff Bay, the Salt Ponds, and elsewhere their configuration strongly 
Suggests that they were originally lagoons on the interior side of barrier 
` reefs. 
These morasses are most extensive at the mouth of Black River, St. 
Elizabeth, and at Long Bay, west end ; and near Morant Point, east end, 
Where they extend back from the sea for two or more miles. Elsewhere 
hey are elongated narrow strips less than a half mile in width and occur 
between the sea and the back coast border. 
These formations occur relatively to the Manchioneal, Hopewell, and 
arbican formations of the Coastal Series, in the same manner that the 
Coastal Series, as a whole, occurs relative to the rest of Jamaica, 
1. e. they are deposited in eroded bights and on eroded plains cut out 
of the preceding formations. 
The Bogue Island Formation. 
: The last to be described, but by no means tho least interesting forma- 
tion of the Jamaican sequence, is that which composes a number of atoll- 
like islands in Montego Bay about one mile west of the city. These lie 
Just off shore in the greatest indentation of the bay. Looked down 
Upon from the elevated back coast hills, as seen in the illustration 
late XX.), these islands appear to be a group of typical coral atolls, 
Consisting of small circular belts of land enclosing interior lagoons. 
; hen visited and closely inspected they are found not to be of this
