468 XANTHOPHILUS PRINCEPS 



Mr. Gronvold's illustration of this unique specimen, whicli 

 he was enabled to make through the kindness of Prof. Bocage, 

 will best show how it differs from its closest ally, X. capensis, 

 in its much shorter bill, the eulmen not so straight, the pale 

 yellow of the crown extending on to the nape and forming a 

 well-defined cap, and a narrow line of black separating the 

 golden forehead from the lores. An adult male variety of 

 X. capensis, obtained by Mr. Butler at Caledon, and formerly 

 in my own collection, has nearly as much olive on the sides of 

 the head as in X. temporalis.
