L. iheanus, tlie species now described as new, is coloured 

 quite like the Abyssinian form referred to L. bozasi, and has

A FEW weeks ago Mr. Rowland Ward had on exhibition at 

 his establishment in Piccadilly tlie mounted skin of a hornless 

 okapi remarkable on account of its large size, a feature in
