tion and almost 15 years of field experienee in the eountry, Crawford-Cabral (1991) reviewed the 
different proposed biogeographic divisions of the country, and proposed a new map and divisions 
based on mammal data. He agreed with the main “north-south” division proposed by Bocage, call¬ 
ing Bocage’s “northern” region the “Western (or Guinean) Sub-region,” while the “southern 
region” was the “South-Eastern (or Sudan-Zambezian) Sub-region” (Table 4). Both were further 
divided: the “Western (or Guinean) Sub-region” was divided into the “Cabinda sector,” containing 
the “Mayombe” and “the coastal” zones; the “Escarpment and Angola’s Northeast sector,” 
containing the “Congo sub planaltie,” the “escarpment,” and the “northeastern coast” zones; and 
the “Northeastern Angola sector,” containing the “Cuango-Casai area,” whereas the “South-East-
