HILL: GEOLOGY OF JAMAICA. 155 
of which, as determined by T. Rupert Jones and W. K. Parker, are 
nearly all identical with those dredged by Barrett in the adjacent sea 
% depths which indicated at least 100 fathoms. 
The species determined by Jones and Parker! are as follows : Nodo- 
Siria raphanus ; Nodosaria raphanistrum ; Dentalina acicula ; Frondicu- 
laria complanata ; *Cristellaria calcar ; *Cristellaria cultrata ; Cristellaria 
“tulata; Cristellaria italica ; *Orbitolina (Gypsina) vesicularis ; Buli- 
Mina ovata; *Lituola (Haplostiche) soldanii; Vertabralina striata; 
"Cuneolina pavonia; Vagulina acumen; Vagulina striata. 
Eight of these species have been found living in the adjacent waters 
Y Barrett. Five of the species (marked *) are the same as those 
identified by Bagg in the Bowden beds. Those genera which are 
‘pecially characteristic of the Oceanic White Limestone and Cambridge 
eds, such as Orbitoides, Nummulinæ, Operculina, Heterostegina, and 
Amphistegina are absent here,? as well as from the Bowden beds. 
In the Falmouth beds of the north and south coast of the west end 
of the island, the third, last, and most recent horizon of abundant well 
Preserved fossil remains of Post-Pliocene Mollusca are met. They in- 
chide Lucina, Cardium, Arca, Solen, and many other genera of bivalves, 
and among the Gasteropoda forms of Turbo and Strombus, such as 
Wound off the present coast, and great numbers of a small Bulla, 
Which ig especially abundant in similar deposits of Yucatan, Barbuda, 
d other West Indian localities. This sub-recent or Pleistocene fauna 
S well worthy of careful study and analysis by those interested in the 
Study of the paleontology of the Mollusca. 
Fauna of the Elevated Coral Reefs. — In the elevated reef of the 
“astal Series, corals are everywhere found, either as the chief material 
of the elevated reefs, as previously described, or as single specimens or 
"agments in the contemporaneous marls, 
aughan has identified the following species of coral in the various 
Oboruco collected by us.
