meters. Other birds in the series in the Museum of Comparative 

 Zoology agree with the limits set by Swann. 



Sclater " gives the range of this race as extending, " * * * 

 south to Uganda and the Great Lakes," while the typical form ranges 

 from South Africa north to Ivitui, Kenya Colony. A juvenal male 

 from Luchenza, Nyasaland, formerly in the collection of H. Kirke 

 Swann, now in the Museum of Comparative Zoology, is extremely 

 dark above and agrees perfectly with Hartert's ^® diagnosis of the 

 juvenal plumage of abyssinicus. The specimen was identified as 

 abyssinicus by Swann, but was apparently not made use of in his 

 account of the distribution of the races of the lanner falcon. It is 

 slightly questionable if this individual is really abyssinicus, sepa- 

 rated as it is from the range of that race by some 1,200 miles, and not 

 merely an aberrant individual of typical biarinicus. 



When reidentifying the hawks in the Museum of Comparative 

 Zoology, James L. Peters brought the following facts to my atten- 

 tion. One of the so-called races of Falco biar7?iicus, the form feldeg- 

 gii, seems to be worthy of specific distinction. The cere in feldeggii 

 is narrower than in any of the races of biarmicus, the feathers of the 

 lores extend beyond the margin of the nostrils, and the tail is pro- 

 portionately longer, more like that in Hierofalco. I have personally 

 reexamined all the available material and my findings agree fully 

 with those of Mr. Peters. 



The species bianniciis is entirely African and Arabian (including 

 Palestine) in distribution, and contains the following four races : 



1. F. b. biarmicus. — Africa from the Cape of Good Hope north to 

 Angola and Kenya Colony. 



2. F. b. tanyptenis. — Arabia, Palestine, EgyjDt, Nubia, south to the 

 Anglo-Egyptian Sudan (Khartoum). 



3. F. b. abyssinicus. — Ethiopia, Shoa, Gallaland, Eritrea, south- 

 western Arabia (Aden Protectorate), west to Nigeria, south to the 

 lakes of central Africa, possibly to Nyasaland. 



4. F. b. erlangeii. — Africa north of the Sahara from Tunis to 

 Morocco.
