BV P. CAMERON. 359 



Apart from the difference in colouration, the present 

 species may be known from K . frogijattii by the difference in 

 the form ol the areola : in E. froggattii it is almost twice 

 longer than wide ; in the species just described, horseshoe- 

 shaped, about one-fourth longer than wide.
