 and smaller spots of brown pigment, most plentiful round 

 and below the eyes and on the bare part of the cheek, but 

 absent on tlie upper and lower lips and on the nose. Upper 

 lids whiter than surrounding skin, with white eyelasiies.

 front and at the sides this black crown is sharply defined by 

 the greyish-white hair forming a narrow brow-band and by 

 the hair of the same colour clothing the cheeks and the area 

 behind the ear. The hairs on the cheek forming a long
