Type: Hyptiotes paradoxus (C. Koch). 
This genus is first mentioned by WALCKENAER 1833 in his above 
cited Mémoire sur une nouvelle classification des Aranéides under the name 
of Uptiotes, but not otherwise characterized, than that it is erroneously sta- 
ted to have six eyes, like Scytodes and Omosites, together with which ge- 
nera it is placed in the family " Cellulicoles”. It was not till in 1837?) that 
WALCKENAER gave a recognizable, though inaccurate, diagnosis of the ge- 
nus " Uptiotes”. But during this interval, 1835, the animal, which was the 
type of WALCKENAERS Uptiotes, had been described by C. KocH under the 
name of Mithras paradoxus (see Synonym.) Under such circumstances it 
may seem dubious, which generie name ought to be preserved; I for my 
part should have unreservedly given the preference to the name Mthras, 
if it had not been previously engaged for another genus of animals; but 
that being the case?), the Walckenaerian name must be adopted. 
As Uptiotes is unquestionably formed from vzzos, resupinus, the name, 
as has been already observed in Agassiz’ Nomenclator Zoologicus, must be 
written Hyptiotes. 
The systematie position of this genus has been, and still is, a sub- 
ject of much dispute. It is remarkable that as long as WALCKENAER and 
Kocx believed it to have only 6 eyes, they acknowledged its intimate con- 
nexion with the Æpeiroide. Koch even introduced it into that family >).
