Pilumnoplax heterochir (Studer). 



1882. Pilumnus heterochir, Studer, Abhandl. K. Ak. Wiss. Berlin, part ii. pp. 6, 14, pi. i. fig. 3, a-d. 

 1886. Pilumnoplax heterochir, Miers, Rep. Voy. " Challenger," vol. xvii. part xlix. p. 227, pi. xix. fig. 1, a-d. 



Miers and Studer both call attention to the peculiarity in this species that the 

 palm of the larger cheliped is smooth except at the base, while in the smaller 

 cheliped the palm externally is covered with numerous granules. The fingers of 

 both limbs retain their dark colour in spirit. Studer says that in life the colour is 

 intense orange-red, with only the fingers of the chelae black. 



Locality. — Gough Island, depths 75 and 100 fathoms; the lower depth recorded
