small reddish shaft stripes on the feathers of the lower underparts. 

 However, this varies, and specimens from the Goolis Mountains, 

 British Somaliland, are said ^^ to lack them entirely, in which case 

 the slightly larger size of spilogaster seems the most reliable differ- 

 ence. All the races of Francolinus sephaena are average ones; the 

 species seems to be in an active phase of evolution. 



FKANCOLINUS AFRICANUS ULUENSIS Ogilvie-Grant 



Francolinus uluensis Ogilvie-Grant, Ibis, 1892, p. 44: Machakos, Kenya 

 Colony. 

 Specimens collected: 



One adult female, Thika River, at big western bend, Kenya Colony, 

 August 29, 1912. 



Soft parts : Iris brown ; bill brownish black, dirty yellow at base, 

 on sides, and below ; feet brownish yellow ; claws brown. 



I have not enough material to attempt a revision of the races of 

 Francolinus africanus and therefore follow the arrangement given 

 by Sclater ^^ adding to his list the subsequently described form 

 archeri. Even if we restrict our attention to the northeast African 

 races, the situation leaves much to be desired. Mackworth-Praed's 

 review ^° is unfortunately vague with regard to Ethiopian, Somali, 

 and north Kenian birds, chiefly because of lack of adequate material. 

 It is difficult to show the ranges of the races on a map, as the ranges 

 are distinct chiefly in the one direction a map does not show, alti- 

 tude. Thus, eUenhecki occurs on Mount Arussa, for example, while 

 archeri is found at the base of that mountain. 



The race uluensis is the form found in the interior of Kenya 

 Colony, chiefly in the highlands, but recorded from the Taveta dis- 

 trict as well (altitude about 2,500 feet (750 meters)). 



The single specimen collected differs from three males from Guaso 

 iSyiro, Fort Hall, and Nairobi (all Kenya Colony) in that it has the 

 entire throat spotted with black; the spots are smallest anteriorly 

 and elongate and become terminally expanded towards the base of 

 the throat. The three males vary in this respect. A young male 

 (spurs present merely as small knobs) has the entire throat immacu- 

 late white; the other two have the lower and lateral parts spotted, 

 only the upper and middle throat being unmarked. However, the 

 spots are not elongate, but roundish. The reddish marlcs on the 

 breast vary in shade from bright chestnut to a deep rufous bay, 

 being brightest and most chestnut in the young male, darkest in the
