Dr. van Someren Coll. 
Obs. This species has been confused with Apus apus 
shelley, which is found in Hast Africa, but which is a paler 
greyish-brown bird like Apus pekinensis. The nearest to 
this species is Apus roehli, which has the mantle dark blue- 
black. It is distinct from Apus nyanze and marwitzi. These 
birds breed in the cliffs at Lake Nakuru, along with other 
species. 
Mr. P. F. Bunyarp exhibited a clutch of four eggs, which 
he believed to be those of the Hobby from County Cork, 
Ireland. But the birds had not been identified. 
The Rev. F. C. R. Jourdain considered that it was 
impossible to distinguish with certainty the eggs of the 
smaller Falcons, and to exhibit such eggs as those of 
the Hobby from Ireland, with no authentication whatever, 
was to bring oology into disrepute. There was no reason 
to believe that the eggs in question were anything but 
Kestrel’s. Messrs. Hartert and Stuart Baker agreed with 
Mr. Jourdain, 
The Rey. R. J. Hale challenged anyone present to 
produce an authenticated clutch of more than three eggs of 
the Hobby from anywhere in the British Isles.
