HILL: GEOLOGY OF JAMAICA. 147 
epoch than the contributions of the class of writers previously men- 
tioned. His information was supplemented by the recent field work of 
Simpson and Henderson and myself. In this paper he describes Guppy's 
Collections, which are accompanied with no information concerning their 
locality, except that they were collected by Vendryes. We have made 
inquiries of Mr. Vendryes, through Professor Duerden, concerning the 
locality of his collections, and he has stated, in a letter dated October, 
1897, that they were made at Bowden. 
It is sufficient to state, as far as the described species of the so 
Called Miocene and Oligocene Mollusca are concerned, that, instead of 
aving wide and general distribution in Jamaica, they aré known to 
cur in only one or two restricted localities, one of which, Bowden, has 
furnished all the recorded species. 
In but few other places in the world are fossils so beautifully pre- 
served, so representative of diverse orders, or so numerous in species, as 
in the gravels of the Bowden beds at the foot of Captain Baker’s hill, 
orant Day. These occur only two or three feet above sea level, in the 
bluffs of the highway where it starts up the hill. A single barrel of this 
Material, recently collected, has yielded more than three hundred species 
of marine Mollusca, in addition to land and fresh water species, besides 
Wenty-six species of corals, five species of Foraminifera, and traces of 
"yozoa and Echinodermata. 
ln the Bowden beds an entirely new foraminiferal fauna appears, and 
Me which occurs under entirely different conditions from those of the 
°ntpelier beds, representing for the second time in the Jamaican history 
Shallow water foraminiferal fauna. These are of large macroscopic 
torture, are found in the Bowden gravel beds, and are of contempo- 
“aheoug origin with them. Following is a list of the genera collected 
Y me from this horizon at Bowden, as determined by Bagg : — 
& 0ramanafera. — Haplostiche soldanii (Parker and Jones); abundant in 
“tiary, "l'extularia barrettii (Jones and Parker); Miocene to Recent. 
“Xtularia trochus, d'Orb. ; Cretaceous to late Tertiary, Recent. Orbicu- 
Na adunca (Fichtel and Moll); Miocene to Recent. Orbiculina com- 
Pressa, d'Orb.; Miocene to Recent. Cristellaria cultrata (Montfort) ; 
*hiefly Tertiary. Cristellaria cassis (Fichtel and Moll) ; Cretaceous to 
“cent. Cristellaria calcar (Linné); Miocene and Pliocene chiefly. 
p n globulus (Reuss) ; very abundant in Miocene. Gypsina vesi- 
"is (Parker and Jones); same range as G. globulus. Cuneolina 
Pavonia, d'Orb.; Cretaceous (1). Cuneolina sp.; perhaps new. Vaginu- 
Ma legumen (Linné); Trias to Recent. Nummulites ramondi, d'Arch.,
