Pterocles lichtensteinii sukensis Neum. op. cit. 



Males rather darker above than in P. I. lichtensteinii ; 

 females considerably darker above and below, dark markings 

 very broad^ light markings much deeper in tone.

Wing : (J (4 measured) 180-197 mm. ; ? (2 measured)

Since writing the above I have been able to examine 

 five males and four females of this race collected by 

 A. Blayney Percival in British East Africa, which agree 

 perfectly with tlie other specimens of this race, and which 

 further show that the cross-barriug on the belly of the 

 males is much more defined and clear than in males of either 

 P. /. lichtensteinii or P. /. arabicus. 



The wings of these nine specimens measure : males 175— 

 187 mm. ; females 171-185 mm.

This Sand-Grouse was common.] 



This subspecies differs from the true P. q. quadricincius in 

 its larger size, darker and broader markings of the upper 

 surface, and generally richer tone throughout. On the 

 crown the streaks are more clearly defined and broader, and 

 the white markings on the forehead are perhaps slightly 

 broader.
