68 T. THORELL, 
WALCKENAER, it is true, says (probably on the strength of the imaginary 
agreement in the number of the eyes) that his Uptiotes is most nearly rela- 
ted to Scytodes, and he takes up Kooms Mithras paradoxus — which he 
considers different from Uptiotes anceps — under the name of Scytodes mithras; 
but he nevertheless remarks, that U. anceps approaches very near to the 
genus Uloborus "in the position of the eyes and the form of the cephalo- 
thorax” }). Afterwards, in 1847 ?), he however maintains, that "the genus 
Hyptiotes in its cephalothorax, maxillæ and abdomen (?) is intermediate 
between the genera Theridium and Argus”, and says not a word of its 
relationship to Uloborus. He accordingly classes it with the Theridioidæ 
("les Retiteles”: loc. cit. p. 521), and is here followed by Simon, who has 
given the genus a place between Æro and Dictyna. Excepting the abnor- 
mally great distance between the anterior row of eyes and the base of the 
mandibles, and the more sharp-pointed teeth on the inferior tarsal claw, I 
find nothing in Ayptiotes that approaches more to the Theridioide than 
to the Epeiroide. — KocH maintains ?), that "this genus, by the posi- 
tion of the eyes, the structure of the body, and by its habits in gene- 
ral(?) belongs to a family of spiders, of which as yet no other genus is 
known to exist”. Of the habits of this genus KocH seems nevertheless to 
have known nothing. In his Uebers. d. Arachn.-Syst., 5 (1850), he ealls 
this new family Mithraides, and refers to it, together with Mithras, the ge- 
nus Poltys (C. KocH) The family Mithraides takes its place between 
Epeirides and Theridides. (Conf. THORELL loc. cit. p. 192). 
BLACKWALL (loc. cit.) and KEYSERLING *) refer Æyptiotes, together 
with Uloborus, to the Ciniflonide BLACKW. on account of the infra-mammil- 
lary organ and calamistrum: even AUSSERER ”) places that genus next to 
Dictyna and Amaurobius (reckoned by him to the family Agalenoide), 
which is so much the more remarkable, as he is acquainted with the 
form, in which Hyptiotes paradoxus makes its web. What we have above 
(see p. 64) said on the matter with respect to Uloborus, holds good also 
of Hyptiotes. By OHLERT this genus was first *) and rightly assigned to the 
Epeiroide; afterwards 7) he included it in the family ZAomisoide, with which
