16. Cepheus latus. Nic. 

 Nic. 446. 

 Found at Epping Forest. 



The English specimens have small hairs on the abdomen, not 

 figured by Nicolet, and the anterior line of tbe abdomen is very 

 slightly sinuated. I cannot help doubting whether the species is 

 really more than a variety of C. tegeocranus.

 Found everywhere ; common. 



The small hairs on the abdomen figured by Nicolet are absent, 

 or very inconspicuous, in the English specimen. 

 Is Nicolet's N. tibialis really a distinct species ?

 Found at Epping Forest ; scarce. 



This and the next species clearly should not have been included 

 in Koch's genus Zetes, which Nicolet has properly joined to Oribata. 

 I have had great doubt if they are really distinct, but on the whole 

 I think that the difference in the so-called stigmatic hairs, which 

 are good specific distinctions in the Orihatidm, the smaller size and 

 rounder shape of the body, and the far greater development of the 

 general dorsal hairs in this species, are sufficient to justify both 

 being retained, subject to future investigation ; this one, at all 

 events, should stand. 



Colour red-brown, sometimes almost red. Gephalotliorax conical, 

 with a constriction a short distance from the front, thence it curves 

 outwards until about the middle, whence the central portion runs 

 nearly straight back rising to the level of the abdomen ; the lateral
