doubt Tertiary and which flank the entire south face of the north 
range, and in attempting to correlate these three he found it 
puzzling. 
Cretaceous.—Tippenhauer’ described a formation in Haiti of 
undoubted Cretaceous age, similar to part of the Cretaceous series 
of Jamaica. This locality has not been visited by the writer. It 
is thought highly probable that Cretaceous rocks exist in the south 
peninsula. Isolated areas of sandstones, shales, and limestones 
occur in this region, expecially between Leogane and Jacmel, where 
the remnants are engulfed in late Tertiary intrusives and are 
generally metamorphosed (see Plate V, Section B). In this same 
section on the north flank of the hills is exposed a considerable thick- 
ness of tuffs which correspond in character with the Cretaceous 
series of Jamaica. 
In the Monti Cristi Range of Santo ee Gabb? found 
Orbitoides. ‘There is probably present there an upper Cretaceous 
formation of sandstones and shales, possibly the equivalent of the 
Richmond of Jamaica, which he failed to differentiate structurally 
from the overlying Miocene. 
B. EARLY TERTIARY LIMESTONES 
The several thick formations of limestone in Haiti have not been 
differentiated and there are several problems connected with them 
which are worthy of future work. With the exception of small 
areas of volcanic or intrusive rocks the entire central range, the 
Montagnes Noires, and a large belt along the south side of the 
north range are of limestone. Great thicknesses are developed 
and owing to continuous exposures the entire series can be carefully 
studied. From casual observation the series seems to consist of a 
basal member with considerable sandstone and above this a great 
thickness of very compact, light-gray or white, foraminiferal lme- 
stones, often very finely bedded but generally massive, and with 
intercalated beds of coralline limestone (Figs. 1 and 2). 
This series rests on the older complex and the unconformity is 
well exposed at several places along the south side of the north
