BEJA AREA. 



Specialized collecting will probably reveal a snail but 

 interesting specialized tick fauna mixed v;ith the Fashsr-Butana 

 fauna that exists on the coastal plains and in valleys of the 

 eastern slopes of the Red Sea Hills. This Area night be sub- 

 divided into a southern sector containing tropical ticks such 

 as R. e. evert si and B. decolor atus , species that nake their 

 last stand aiaong the "Eyalonnas, R. s. sanguineus , and 0. 

 savignyi . In the north, even th'ese'"are lost but Ilyalonna and 

 R. s. sanguineus populations are denser than in the desert and 

 undiscovered Palaearctic species are expected to occur. The 

 preponderence of Hyalonna species provides this Area v/ith a 

 strongly Palaearctic aspect. Specialized Sonali tick fauna 

 of the more southerly coastal plains is not known to reach the 

 Sudan. The composition of tick species that intrude into this 

 Area has some similarity with that further south along the 

 coast but population densities appear to be much lower.
