Was always met with in small groves where, for the most 

 part, it frequented the tops of the tall trees. If frightened it 

 tiew only about 10 meters to an adjacent tree where it would 

 settle down again.

Cerchneis Hnnunculus tinnunculus (L.). — Rchw. I. p. 641. 

 1 Q ad. 13. 5. Eldoret. 



From Eldoret in the direction of Elgon the road at first 

 passes through the acacia steppe. Close to the road a little 

 falcon sat perched on a telegraph wire, which on closer in- 

 spection turned out to be the above-mentioned. 



In the collections of the Zoological Institution at the Uni- 

 versity of Lund there are two specimens from the slopes of the 

 Himalaya and in comparing my specimen with these I found that 

 it was exactly like them. 



The colour of the whole of the back is considerably paler 

 than in typical T. t. tinnunculus. The head is brown with fine, 

 black shaft lines. The dark, blackish patches of the back form 

 transverse folds. The tail is brown with 10 transverse-bands.

At first I thought was that this specimen, owing to the pale 

 colours of the plumage, was C. t. saturatus, and li a r t e r t in 

 his work „Die Vogel der pal. Fauna", p. 1086, says with reference 

 to this falcon that „Genaue Verbreitung noch festzustellen". 

 Bannerman (Ibis 1910 p. 322) has reported this bird from 

 North Somaliland on the 18 th July — 25 th August. — My specimen 

 from the 13 th May is just in the moulting stage. 



Nevertheless, I am now convinced, after comparing it with the 

 specimens at the Berlin Museum, that it is only a very pale 

 specimen of C. t. tinnunculus.
