coral of Europe. Probably the stratigraphic occurrence of the latter in 
Jamaica was not properly represented to Duncan, and it may haye come 
from the Cretaceous formations of that island, in which some of the 
limestone (notably of Clarendon) is as “hard and white” as any of 
the other white limestones. 
Fauna of the Pliocene Formations. —In the Pliocene, Manchioneal, 
and Mulatto River beds of the Coastal Series, we have the first un- 
doubted appearance of the modern reef building compound corals in the 
Jamaican sequence. In these two localities of supposed Pliocene ages 
the forms occur sparsely as single heads in the former, and as a thin 
stratum of true reef rock about one foot thick in the latter. 
Vaughan has recognized an Orbicella, probably radiata, and a Mean- 
drina from these beds. 
In discussing a species of Terebratula reported by Guppy from Trini | 
dad, Etheridge? distinctly notes that * none occur in the Tertiary of 
Jamaica, although careful search was made through the collection." 
De la Beche says? “At Manchioneal Harbor the white marl contains 
corals, spines of Echinites and Terebratule, besides casts of other shells.” 
Barrett, in a note which was published by Woodward in the “Critic” of 
February 1, 1863, also noted the occurrence of Terebratulidee in the 
new Tertiary of Jamaica, 
We were fortunate to find in these beds at Manchioneal two Terebra- 
tula forms which have been determined by Schuchert to belong to the 
genus Liothgrina. Most of the specimens are L. vitrea, Borne, and 
one specimen is probably L. bartletti, Dall. The former is not know? 
as a living species in the West Indies, but is a common species of the 
Pliocene of Sicily. 
There is also a single specimen of a large and beautiful Caviolina, about 
one centimeter long, very much resembling the figured specimens from 
the Pliocene of Italy. From the so called Pteropod marls, whioh are 
probably allied in age, Etheridge reports? three genera of Pteropods, 
to wit, Oleodora, Creseis, and Cuvieria. The Manchioneal beds conta 
but few other molluscan remains, only a few moulds and casts having 
been found by me. Barrett, who collected more thoroughly, is said 60 
have found sixteen species of recent Mollusca belonging to the surroun” 
ing seas in this marl.* 
The “ Pteropod Marls” of Barrett — our Manchioneal beds of SUP 
posed Pliocene age — contain still distinct foraminiferal fauna, the species
