BIRDS OF ETHIOPIA AND KENYA COLONY 495 



the throat being whitish barred witli black. Known only from the 

 types. 



6. J. r. thorhechei. — Cameroon. Differs from pulchricolUs in being 

 more reddish brown above, and in having a larger bill. Bannerman 

 and Bates *- write that their five specimens of thorhechei have bars 

 on both webs of the longer remiges while according to Hartlaub's 

 description *^ of pulchricolUs^ in the latter form these bars are almost 

 obsolete on the inner webs, except on the first primary. 



The specimens brought back by the Frick expedition are in fairly 

 fresh plumage and are all fully adult. Granvik ** notes that in 

 cosensi young birds have the sides of the throat banded brown and 

 black instead of white and black as in adults. This is also true of 

 aequatorialis. The measurements of the adults show that males 

 are slightly larger than females : Wing, male 91-93, female 89-89.5 ; 

 tail, male 7G-Y9, female 77-78; culmen, male 16.2-17, female 15-16.5; 

 tarsus, male 20-22, female 20-21.5 millimeters. 



In Jynx ruflcollis the outermost primary is longer in the juvenal 

 plumage than in subsequent ones, but the difference is not as great 

 as in Jy7ix torquilla. 



The altitudinal range of this wryneck is quite considerable. 

 Mearns collected the present series at an altitude of 9,000 feet (2,700 

 meters), while other specimens have been taken as low as 5,000 feet 

 (1,500 meters). The range is not as large as that of cosensi, where 

 the limits as far as known are 3,400 feet (1,030 meters) (Simba) and 

 9,000 feet (1,700 meters) (between Londiani and Eldoret).
