All the specimens taken by the Helga belong to the typical 

 form of the species and none to the var. abyssorum, Milne- 

 Edwards. This variety is distinguished by the following 

 characteristics :- There are few dorsal setae on the eyestalks ; 

 there is a small tooth at the inner edge of the front border of 

 the second joint of the antennal peduncle ; there are many 

 strong and sometimes spinous granules on the chelipeds ; 

 there are granules and rugosities on the lower part of the carpus, 

 propodite and merus of the walking legs. 



The variety and the typical form are connected by numerous 

 transition forms (Milne-Edwards and Bouvier, 1900).
