sampling periods ( viz 
of reptile assemblages in habitats of the Abydos Plain. 
May 1988, April 1989, July 1990). 
This also was the case for larger goannas such as Varanus 
Snakes from the three families were infreqi

captured (or recorded) on the major sampling sites, and 
juveniles of these were 
occasionally pit trapped, these 
only occasionally at the 20 subsidiary 
sites.

Consequently, they were not included in
