 dern authors foUow T. Thorell in dividing the Uropygi into 

 two tribes: Oxopoei and Tartarides; but each of these con- 

 tains only one family. Of the latter one, the Tartarides, seven 

 species have been named, but only six really described, and 

 two of these are only male and female of the same species. 

 The seven species have been referred to four genera, of 

 which, however, two are completely untenable, and the third 

 genus deviates so slightly from that first established that we 

 can only accept it as a subgenus. 



Some years ago the eminent Arachnologist Mr. Eugéne 

 Simon presented us with three (female) specimens of a new 

 species of this group; we found it useful to give a detailed 

 description of this form, thinking that we could contribute 

 somewhat to the knowledge of the structure of the group 

 and to the conception of its genera. When we had nearly
