282 NOTITATES ZOOLOOICAE XXIV. 1917. 



from the Salt Range in North-west India and another from Kandahar are not 

 distinguishable from those of Farsistan, so that I think this ter-meuleni requires 

 confirmation, unless it is quite restricted to Arabistan. 



In the Catalogue of Birds, xxii. p. 126, the distribution of heyi, as I have 

 said above, includes that of cholmleyi, and, moreover, it is said to extend " east- 

 wards to Muscat, Persian Gulf." That is a rather sweeping statement, for 

 nothing was then kno^wi of any Ammoperdix between the west coast of the 

 Red Sea and Sinai and Muscat, though Riippell, in 1845. said that his Jieyi 

 occurred also at Djedda. Therefore the isolated occurrence at Muscat was 

 remarkable and gave rise to doubts of its identity with the other subspecies. 

 Now several specimens are in the British Museum from Muscat. Mr. Bury 

 found some near Timil in South Arabia, and a female has been obtained near 

 Lahej, north of Aden. One may therefore say that an Ammoperdix ranges from 

 Lahej (Aden) to Muscat. This form, however, is neither A. h. heyi nor A. h. 

 cholmleyi. The males agree with the latter in coloration, but have the two white 

 loral patches, more or less completely connected by a white line. The ? is like 

 those of A. h. cholmleyi. Wings of the males, 125-129 mm. 



I name this form : 



Ammoperdix heyi intermedia subsp. nov. 



Type (in the British Museum), S ad. Timil, South Arabia, Bury coll. 

 I therefore distinguish the following forms of Ammoperdix : 



1. A. heyi heyi (Temm.), 1825 : Sinai Peninsula north to the Dead Sea 



and ravines of the Jordan Valley. 



2. A. heyi cholmleyi 0. -Grant, 1897 : western shore of the Red Sea, Nubia, 



Egypt north to Heluan (Wadi Hof). 



3. A. heyi intermedia Hart., 1917 : South Arabia. 



4. A. griseogularis griseogularis (Brandt), April 1843 : Greater part of 



Persia, west to Birejik and Kum-Kale on the Euphrates, north to 

 Transcaspia and Buchara, Afghanistan, Baluchistan to Sind and the 

 Indus, and across the Indus Valley to the Khariar Hills and Salt Range 

 in the Punjab. 



5. A. griseogularis ter-meuleni Zar. and Loud., 1904: Arabistan ; distribu- 



tion and constancy of differences require confirmation. 



V. FORMS OF PERDIX PERDIX. 



The " Grey Partridge " being distributed over neariy the whole of Europe 

 and large parts of Western Asia, and not a migratory, but an entirely or almost 

 entirely sedentary bird, might a priori be expected to form a number of local 

 races. This expectation is realised, though not to such an extent as one might 

 have thought. In the Cat. B. Brit. Mus. xxii. no subspecies were recognised, 

 nor could the author be expected to describe any, as the series in the British 

 Museum was then very poor and deficient in nearly all the most striking forms, 

 and even now it is poor ; for example, there is only one specimen of the Spanish 

 Grey Partridge, not a single one from Italy, none from Brittany or Normandy,
