is that by Meinertzhagen,*^ while Bannerman,** Neumann,*^ Ogilvie- 

 Grant,^° van Someren,^^ Granvik,^^ ^nd Zedlitz ^^ have all recorded 

 new data and made corrections where necessary. I have read all these 

 and other contributions and have carefully studied about 100 speci- 

 mens of all the forms of the species. As a result I have come to the 

 conclusion that while there is an unusual degree of variation shown 

 in all the races, yet on the whole the geographic variations are 

 greater than (although often rather obscured by) the individual ones, 

 and that the arrangement followed by Sclater ^* is correct. 



FiGurtK 7. — Outermost rectrices of five individuals of Uriolus monacha permistus showing 

 variation, with a figure (lower right) of the same feathers of 0. m. monacha for com- 

 parison. 



The enormous variability of the rectricial pattern is shown in the 

 accompanying figures of the three outermost rectrices of five adult 

 males from southern Shoa (fig. 7). For purposes of comparison 

 the pattern of these feathers in an adult male of the nominate form 

 is included, and is easily distinguished by the relatively small amount 

 of black.
