ment of the teeth differs from that of the other species. 

 The seventh ring is not always so much expanded, and in 

 these cases the animal is slenderer. The form of the 

 antennae above described is due perhaps to the manner 

 in which the animal was preserved. The colour is yel- 

 lowish-gray, the three last rings are horny, reddish- 

 brown, the tips of the forceps very dark. 



During life the other segments are white and 

 soft; the body is clothed with fine scattered hairs, 

 which are most numerous on the antennge and on the 

 posterior segments. 



The length of the body without the antennsB is 23- 

 26 millimetres. 



Length of the antennae 6-13 millimetres. 



Length of the abdomen 15-17 millimetres. 



Breadth of the seventh segment 2f-4 millimetres. 



Last segment and forceps 4-5| millimetres.

M. Humbert has also described^ a species of this 

 genus found in Mexico. It is considerably larger than 

 the /. solifugus, and the antennae have from forty-five 

 to forty-eight segments. The forceps resembles that 

 of the European species, but differs in details.
