1920.] the Birds of the Anglo- Egyptian Sudan. 827 



These Pigeons from the Red Sea Province (Gebeit is some 

 50 miles W.S.W. of Suakin) appear to be nearest to the 

 Egyptian form C. I. schimperi Pp., but tliey do not agree 

 with that race exactly. They appear to be larger on the 

 whole than Egyptian birds and quite distinctly darker. 

 Neither this race nor C. I. schimperi have any definite white 

 patch on the lower back, but the light colour of tlie back, 

 which is the same as that of the scapulars and wing-coverts, 

 meets the dark colour of the rump in a definite straight line, 

 whereas in C. I. palcestince of Zedlitz, J. f. O. 1912, p. 339, 

 there is on the lower back — in all our specimens at least — 

 an intervening '^ buffer '^ patch of white. Again, on 

 examining southern Arabian birds this same absence of any 

 white is noticeable, but these again are darker still and in 

 fact are approaching the dark C. I. intermedia of India. 

 On the other hand, the only specimen in front of us from 

 Muscat h;;s, like western Persian i)irds (? C. I. gaddi 

 Sarudny), a good deal of white. It appears, therefore, that 

 we have an intergradution from the Egyi)tian bird, through 

 the Red Sea Province birds, and the southern Arabian birds 

 to C. I. intermedia of India, while the Palestine race and the 

 Persian Gulf race may possibly be more closely connected 

 with C. I. livia of Europe. Dr. Hartert, Nov. Zool. xxiii. 

 p. 84, is of opinion that C. I. 2:>alcBstince is identical with 

 Arabian birds, but in that case there either must be two 

 l)irds in Palestine, a dark-backed and a light, the former of 

 which w'e have not got here, or his southern Arabian birds 

 must be different from ours.
