The nature and form of individual mounds vary greatly and the 
characteristics listed below are generalized descriptions of mounds 
found in the Distrito Federal and Emas Park. 
Cornitermes cumulans (Fig. 3 a,b): The mound has a very hard 
outer shell of soil surrounding a soft inner core of carton (fecal 
material, communited plant material add bits of soil) which often 
extends below ground as much as 40 cms. The galleries are large and 
unlined. 
Nasutitermes sp. (Fig. 3 c,d): The mound is domed with the outer 
several centimeters softer than the inner core (as in arboreal Nasuti- 
termes and Constrictotermes) and often extends 25cms under- 
ground. The internal structure consists of thin-walled, convoluted.
