proximity with N. memdionale, Hoek, which I have regarded as a synonym of A. 
(jracilipes, Miers. N. hiemale is, however, a much larger species, and differs in certain 
proportions of the body and limbs, as shown by the measurements given above. The 
greater length of the proboscis and shortness ol the cephalic segment are noteworthy. 
There is also a characteristic difference in the fingers of the chelae, which are much 
straighter, meeting along their length when closed. In N gracilipes the movable finger 
is strongly arched, and the fingers gape widely even when the points cross for some 
distance.
