borne out by series, and that there is not the slightest difference whatever in 

 the coloration of the throat, etc., it cannot be denied that the upper surface of 

 South Arabian examples is generally slightly brc\\Tier, darker. 1 think it thtic- 

 fore advisable for the present to admit reichenowi as a subspecies rather than to 

 rule it out altogether. 



It would be interesting to compare a good series from Muscat. The few 

 specimens in the British Museum seem hardly distinguishable from P. x. xcin- 

 thopygos. 



The wings of Palestine males measure 98-100, females 91-95-5, those of 

 South Arabian males 95-98. once 100, females 88-95 mm. 



Tchitrea viridis ferreti an subsp. nov. 



Typical T. viridis from West Africa have the back much paler rufous. 

 Arabian specimens agree in colour with the form ferreti frc m north-eastern Africa, 

 but nearly all have the bill larger. I would, however, like to see a bigger series 

 before giving a name to this apparently new subspecies. Bury sent us three 

 specimens from Wasil. 



Aerops albicollis major Parrot.

 to Zambesi, east to Uganda). ,

There are two very distinct forms of Aerops albicollis, a western, A. albicollis 

 albicollis, and an eastern, A. a. major. The latter is distinguished frcm the 

 former by larger dimensions, chiefly larger bill and longer wing, and also more 

 bluish tail, generally without any greenish tinge. All Arabian skins are very 

 typical major, but the few Uganda specimens which I have seen belong to 

 A. a. albicollis. 



Columba livia palaestinae Zedl. 



Colnmba livia palaeslinac Zedlitz, Joiirn. /. Orn. 1912. p. 339 (Palpstine). 



We have a o and $ from Menakha, 7 and 27.1.1913, and the British 

 Museum has also a pair from Menakha, as well as a <? frcm Hajeilah, 2,080 ft. 

 Sclater called these birds C. I. intermedia, but this is a mistake, for C. I. inter- 

 media is the form from tropical India and a much darker bird. The Arabian 

 birds are indistinguishable from C. I. palaestinae, and this form is nearest to C. 

 I. schimperihom Nubia and Egypt, and of similar dimensions, but it is slighter 

 darker, especially on the under tail-coverts.
