On ene side the fourth primary is only about 3 mm. shorter 

 than the third, but on the other wing the difference is 13 

 mm. although, of course, the fourth primary is fully de- 

 veloped.

It vas a very astonishing fact to me when I saw this 

 fine series of Turacos and found that it did not consist of 

 Turacus hartlauhi, which was so well known to me from 

 Nairobi, Kenia etc, but did belong even to another genus, 

 in spite of the great general resemblance. The distance 

 between Nairobi and Juja is not great, but at the former 

 place I never saw Gallirex. All Turacos there as well as at 

 the Escarpment and in different parts of the Kenia-forests 

 were, as far as I could see, Turacus hartlauhi. The latter is 

 also the Turaco of the Kilimanjaro region, the Meru moun- 

 tain, and Gr. Arusha. In a western direction it extends to 

 Elgon etc. But the distribution of Gallirex chlorochlamys is 

 much wider. It extends from Victoria Nyanza down to 

 Zambesi, and along the coast northward to Mombasa and 

 Taita, and again inland as far as Juja and Donya Sabuk. 

 This area embraces thus partly that of Turacus hartlauhi, 

 and at the same time also the home of some other species 

 of Turacus. It appears, however, as if only one species lived 

 in each tract. So for instance did Percival only collect 

 Gallirex chlorochlamys in the Kikuyu forest (Ibis, 1910), and 

 GuRNEY also the same, but not Turacus hartlauhi (Ibis, 1909). 

 This is very interesting, the more so as the habits of these 

 birds seem to be very much alike as is also their appearance. 

 Turacus hartlauhi belongs, of course, more to the thick moun- 

 tain forests where it lives up to the altitude, where the bam- 

 boos begin to mix with the trees (on Kenia I found it at 

 an altitude of about 2,700 m.). But at the same time it also 

 extends down to the dry forests at the edge of the steppe 

 as at Nairobi, and it cannot be very much difference in 

 altitude between the latter place and Juja.
