A GEOLOGICAL RECONNAISSANCE IN HAITI 739 
This middle division (Las Cahobes) is very thick. On the 
road from Hinche to Thomonde these beds are tilted to angles of 
from 75°—85° and the total thickness exposed is probably over 6,500 
feet. 
Excellent exposures of this divisions occur at many place and 
there are some especially interesting localities near Las Cahobes.

Be (Oh pbper—Maissade Beds 
The uppermost division of this series consists of shales, marls, 
and some sandstones and is characterized by lignitic beds which 
near the town of Maissade are well defined. The division is well 
exposed north and west of Maissade along the Riviére Canot and its 
several branches, notably the Riviére Fond-de-Gras, Rio Piedre, 
and Rio Blanco. An excellent section is obtainable on the Rio 
Blanco of that part of the division containing the lignite beds (Figs. 
5 and 6). Following is a detail of this locality and a list of the 
fossils hastily collected from it:
