The male only of this species has been described. Foerster's 

 A. severini is clearly synonymous, the appendages as figured by 

 Martin being exactly like those of my type-male of A. forcipata. 

 This figure is more correct in detail than the sketch sent by me 

 to M. Martin and my own figure, but is sketched with the ap- 

 pendages slightly tipped down, making the inferior appear shorter. 

 The colouration of Foerster's specimen shows it to be a faded 

 immature male.
