tibiae have 5 ov 6 spines, the metatarsi two or more, at least on 

 the anterior legs. The tarsal joint of the palpi is almost cylindrical, 

 not tapering and pointed. The anterior row of eyes is curved back- 

 wards, the posterior, when viewed from above, curves a little for- 

 wards. The distance between the posterior centre and lateral eyes 

 is something greater than the interval between the two posterior 

 centre eyes, which is about equal to the diameter of one of these 

 eyes: the distance between the anterior lateral and centre eyes is 

 more than double as great as the diameter of the lateral eye. The 

 distance from the margin of the clypeus to the anterior centre eyes 

 is somewhat less than the length of the area of the centre eyes. — 

 Mr Cambridge has had the kindness to lend me the only hitherto 

 discovered specimen of this species. Blackwall's figure of it is re- 

 markably good.

A cf of this species has been found by Dr Tullberg in Skane; 

 I have also seen specimens from Scotland , transmitted to me by the 

 Rev. 0. P. Cambridge. — L. obscura <-f is easily distinguished by the 

 lamina of the palpus having at the base, inwards, a strong, erect, 

 pointed and slightly curved tooth : see Blackwall's excellent descrip- 

 tion. His figure of this spider is of little use. 



To Blackwall's description may be added, that the thighs of 

 the l:st pair have one spine above, and that the following thighs are 

 without spines; the tibiae have two spines above, the anterior more- 

 over one towards the apex on each side; these spines are pretty long, 

 those of the tibia? for example double as long as the diameter of the 

 joint. The hindermost metatarsi have one short, fine spine. The 

 anterior row of eyes is sensibly curved backwards; the distance be- 

 tween the margin of the clypeus and the anterior centre eyes is some- 

 thing greater than the length of the area of the centre eyes. The 

 four posterior eyes are situated at equal distances, of less than the 

 diameter of an eye, from each other. The vulva is formed of a short, 

 broad, reddish brown lamina directed backwards, which is twice 

 emarginated at the broadly truncated apex, and accordingly termi-
