I am rather divided in opinion as to whether this species 

 should be referred to Mecistocephalus 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 Oeophilus^ and since 

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

 pleura of the raaxillipedes, such as is seen in the other species 

 of Mecistocephalus^ and the basal plate is wider than in that 

 genus, I decide to refer it provisionally to Geophilus. 



Possibly it is a young example of Mecistocephalus.']

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

 fading to ferruginous on the under surface ; keels and caudal

AntenncB longish, slender; segments 3, 4, 5 long and sub-
