The "black streak behind the corner of the orbit" mentioned by 

 Pocock (1. c.) is not in reality a 'streak' in the usual acceptance of that 

 term, but the long black hairs of the narrow line beneath the white band 

 on the forehead turn backwards and upwards at the corner of the eyes 

 and produce a black line. If these hairs should be shorter in any speci- 

 men, as they most likely would be in certain seasons or age, there would 

 be no black mark at this point, as there are no black hairs growing 

 upwards from the corner of the eyes to form a streak. I emphasize 

 this point, because Mr. Pocock makes it one of his characters separat- 

 ing this race from L. tantalus, and might possibly mislead an inves- 

 tigator with a specimen having shorter brow hairs. 



I am not aware that any intermediates between the two following 

 forms and L. tantalus have been obtained, and it might be criticized 

 that they should have been reduced to races, but they are all so
