C 396 ) 



three skins collected in " Aegypto ntraque." Again, in 1807 (Uis, j). 76), Tristram 

 named the same form " Dn/moica eremita," from examples obtained in the 

 desolate wadis opening on the west side of the Dead Sea, and from Arabia Petraea, 

 i.e. the Sinai Feniusnla. 



There is no mistake that the birds from the Dead Sea, the Sinai Peninsula 

 and the Wadi Hof belong to one and the same form. I have, through the 

 kindness of Mr. Nicoll, been able to compare five of his specimens, inclndiug 

 the t3-pe, two from the Sinaitic Peninsula, and three from Palestine, and there is 

 uo difference whatever between them. This form, the Scotocerca inquictus iiKj/i/etus, 

 differs from all the other forms of S. inquietus, except the much darker .S'. inquietus 

 buri/i Grant from South Arabia, in having a white superciliary line, this being 

 buff or rich cream-colour in the other races. 

 We must distinguish : 



Scotocerca iiiquii'tus saharae. — Sahara of Algeria and Tunisia. 



Scotocerca inquietus inquietus. — Cairo to Sinai and S. Palestine. 



Scotocerca inquietus plat;/ura. — Transcaspia. 



Scotocerca inquietus striatus. — E. Persia, Baluchistan, Afghanistan to 

 Punjab. 



Scotocerca inquietus buri/i. — S. Arabia. 

 All these forms are more fully discussed in the furthcoming fifth part of my
