Outlying tamarix near the oasis of El Gatrun, Fezzan. This peripheral zone of tamarix is 

 typical of most of the larger oases in the Libyan Sahara and provides suitable habitats 

 for several species of Saharan rodents, January 1962. 



*&t 



Date palms interspersed with sandy-clay hummocks supporting tamarix at El Abiad Oasis, 

 Fezzan. The large gerbil, Gerbillus pyramidum, is abundant in the sandy areas around 

 the palm trees where the dense, basal fronds afford shelter and the fallen dates provide a 

 convenient source of food, December 1961.
