the Wadi Titti, east of Socna. More recently, Toschi (1951) recorded a 

 specimen from the Wadi SofFegin and assigned it to C. g. vali. Setzer 

 (1957) recorded the most recent specimen of C. g. vali taken from the 

 type locality at the Wadi Bey. These few specimens constitute the 

 only known records of this subspecies in Libya. 



The Wadi Bey is located about 300 kilometers southeast of the type 

 locality of Ctenodactylus gundi gundi, but the range of C. g. vali 

 probably includes most of the arid transitional desert between the 

 Gebel es Soda and the coast. Most of the broad wadis in this region, 

 which drain northward into the Gulf of Sirte, provide suitable habitat. 

 The drier climate of these interior localities and the irregular scarps 

 which are present on the margins of these wadis differ markedly from 

 the more humid climate of the Gebel Nefusa and its higher and more 

 imposing escarpments. The ranges of C. g. gundi and C. g. vali are 

 thus physiographically and climatically distinct. 



Gundis are unknown from the Gebel es Soda and the Gebel el Harug 

 el Asued, both of which appear to have an abundance of suitable 

 habitat. The Gebel es Soda is also only a short distance south of the 

 Wadi Titti, a previous collecting site for the gundi. In the future, gundis 

 will probably be found to occur in both of these areas. 



Setzer (1957) stated that, during his visit to the Wadi Bey in 1955, 

 his guide informed him that in the past numerous gundis had inhabited 

 the "broken rock scarps" but owing to a severe drought the vegetation 

 had dried up and most of the gundis had died.
