In naming these specimens we found it necessarj^ to 

 examine all the birds of this group from the northern 

 half of Africa, and we found that in most cases we agreed 

 with Neumann's revision of the genus (J. f. 0. 1907, 

 pp. 348-358). 



He, however, uses the name minor for the group to which 

 the Sudanese forms belong, but we find that Pachyprora 

 bella Elliot, Publ. Field Columb. Mus. Orn. Ser. vol. i. 1897, 

 p. 47 : Le Gud, Somaliland, is the oldest name. We have 

 not seen the type, but we have birds from almost exactly 

 the same locality which agree perfectly with the description, 

 and there is no doubt that they are of the same group 

 as B. minor. 



There are, therefore, two groups which occur side by side 

 in north-east Africa, B. orientalis Heugl. and B. bella 

 Elliot. Of these B. orientalis can be distinguished at a 

 glance by the lighter brown, much wider, and less sharply
