margin of the inferior claspers, but projecting laterally beyond the claspers on 

 both sides. Sclerites of the juxta or penis-sheath (;') branched near the anterior 

 third. Harpes divided into four pointed processes, the basal pair being widely

 are united to a solid and somewhat rectangular process, the stem of which is 

 attached to the semi-circular sclerite which supports the first pair of pointed 

 appendages ; collectively these appendages are distinctly antler-like and strikingly 

 characteristic.
