Type: Uroctea Durandit (W ALCK.). 
Before this genus of spiders received the name of Clotho, that name 
had already (in 1808) been appropriated by FAUJAS DE Sr. FONDS to a 
genus of shells (= Saxicava FLEUR.), and had therefore here to be replaced 
by the more recent, synonymous denomination Uroctea, given by L. DUFOUR. 
(Conf. p. 9, note 2). 
In U. Durandi the tarsal claws are coarse, strongly curved, broad * 
at the base, and have from the base to a little beyond the middle about 
10—15 long stout comb-teeth, the points of which lie in an almost straight 
line. The inferior claw is comparatively small, with one tolerably long 
tooth near the base. The female’s palpal claw is very strong, curved almost 
into a half-circle, with about 10 strong blunt teeth, gradually, but slightly in- 
creasing in length when reckoned from the base, where they are very short. 
The second joint of the superior spinners forms in this species (the 
only one of the genus, with which I am acquainted) an angle with the short 
basal joint, and is directed obliquely upward; it is of considerable length 
and strongly compressed from the sides, almost lancet-formed, curved up- 
wards and inwards, rounded at the extremity, without any trace of a se- 
parate lamina there; the spinning-tubes form a narrow, close band begin- 
ning at the apex of the spinner and continued throughout the entire length 
of its inferior surface; they are cylindrical, small, and very numerous. The 
anterior or inferior spinners are short, with a plainly visible but short 2" joint. 
The intermediate spinners are very small.

Type: Œcobius domesticus Luc. 
This genus was created by Lucas loc. cit. for two small spiders 
from Algeria, Qc. domesticus and Œc. annulipes Luc., and were reckoned 
by him among the genera of spiders that have but six eyes. SIMON, who
