it by him; but in any independent arrangement of the Araneidea, I think it ought, in 
conjunction with Uloborus (Latr.), and perhaps Miagrammopes (Cambr.), to form a family 
immediately following the family Epeirides. This opinion is supported by Dr. Thorell, 
who, long before 1 was acquainted with his works, had assigned to Mithras a position very 
near that which it appears to me it should occupy; and more recently, in a work, *On 
European Spiders,’ lately published, Dr. Thorell forms a subfamily of Epeiroide out of 
Hyptiotes (Walck.) and Uloborus (Latr.). 
Hyptiotes paradoxus has as yet been recorded only once in Britain, an adult female 
having been captured in Cumberland in 1863 by Mr. J. B. Hodgkinson (of Preston, 
Laneashire, well known as an acute and untiring lepidopterologist). 
It is a remarkable spider, not only in its general form and appearance, but in the form 
of its snare, which represents a portion only of a regular geometrie or wheel web, and in 
front forms a sector of a circle; it consists merely of three or four lines, radiating from a 
centre, and connected here and there by some cross lines.

The disproportionately large size of the two central eyes of the upper row is a distin- 
guishing character of this spider. Except the single (very young) example described 
(loc. cit.), no other one has yet come under my notice. A recent examination of this 
specimen has raised a suspicion in my own mind that possibly it may be only a very 
young example of Textriz lycosina (Bl.).

— subfusca, Cambr. Ann. & Mag. Nat. Hist., June 1861. 
A careful comparison of the typical example of Agelena subfusca (Cambr.) with un- 
doubted examples of Agelena nava (Bl) has convinced me that the two species are 
identical. In the typical example of the former, the pointed process on the outer side of 
the cubital joint of the male palpus, as also the terminal curved spine beneath the ex- 
tremity of the radial joint, were overlooked by Mr. Blackwall (who kindly examined it 
for me) and by myself. Agelena nava is not rare at Bloxworth in May and June, running 
on the ground and on walls and posts, &c.

This species is allied to T. atrica, but is very much smaller, and is never, I believe, 
found in houses, whereas T. africa is most commonly found in such a habitat. It may
