belong to a group called Anthracomarti, apparently ancestral 
to the recent Pedipalpi (whip-scorpions and allies) and 
Opiliones or harvest-spiders, and in some respects inter- 
mediate between them. The hind-part of the body is still 
articulated to the fore-part, and consists of flexibly joined 
segments. As in typical Arachnida the mouth is at the 
front of the body, and only the first two pairs of limbs take
