1 am rather divided in opinion as to whether this species 

 should be referred to MecistocephaJus or Geophilus] and since 

 there is only one specimen, I refrain from putting it to the 

 necessary anatomical examination of the mouth-parts to settle 

 the point. But since I can detect no definite external cha- 

 racters which absolutely sever it from Geophilus^ and since 

 there is no trace of the thickening of the inner edge of the 

 pleura of the raaxilli pedes, such as is seen in the other species 

 of Mccistocephalus, and the basal plate is wider than in that 

 genus, I decide to refer it provisionally to GeophHas. 



Possibly it is a young example of Mecistocephalusi]

^ . — Colour. Head and upper surface of body pitch-black,

 rising above the middle of the side, small, with rounded 

 anterior angles, and the posterior scarcely produced even at 

 the hinder end of the body ; the keel of the second segment
