 grossen Namaquas und von da nach dem Wendezirkee des Steinbocks, der 

 einzige mittagliche Theil von Afrika") is given, which is, of course, erroneous.

 fixed by W. L. Sclater, Bull. Brit. Orn. Club, vol. 40, no. 245, p. 39, Decem- 

 ber 8, 1919, as Sumatra. The type locality of Falco bassus is therefore best
