falces, niaxillse, labium, tarsi and metatarsi of the legs tinged 

 with yellow-brown. Probably the example described (which 

 is the only one I have yet found), had not long obtained 

 maturity, in which case the colours would perhaps havo become 

 darker in a short time. 



The profile line of the cephalo-thorax shows no difference in 

 the even run, of tho very slightly curved line of the thorax and 

 caput, to the beginning of tho hinder slope. 



The four central eyes form a small square, and are all, as 

 noarly as possible, equally separated from oach other, the 

 intervals being, just about, equal to a diameter of one of those 

 of the posterior pair ; those of each lateral pair are idacod obliquoly, 

 and are nearly, but not quite, contiguous to each other, being 

 also the largest of tho oight ; the interval between the hind- 

 centrals is distinctly less than that between each of them, and 

 the hind-latoral eye next to it. 



This spider is unmistakably allied to some species of Neriene, 

 but differs considerably from them. Among the chief differ- 

 ences are the position of the eyes, of which the posterior row has 

 its convexity directed forwards ; the greater strength of the 

 legs ; and the tarsi, equalling, if not exceeding, the metatarsi in 

 length. On those, and other, accounts it is necessary to establish 

 a new genus for it. 



A single example was found under an old clod of turf near 

 Woolbarrow, on Bloxworth Heath, in September, 1878. 



GENUS NEEIENE, M in part. 



This genus and the next (Walckenaera, Bl.) comprise a vast 

 assemblage of minute spiders, mostly black, or dark-brown, 

 (varying to yellowish-brown in some species) with yellow-brown, 

 reddish-brown, or orange-coloured legs. Among them are some 

 of tho smallest known spiders; the largest does not exceed l-6th 

 of an inch in length; while the smallest is no more than l-25th. 

 There appears to be no sufficient grounds for merely separating 

 the genera JVeriene and Walckenaera, of which this group is made 

 up ; while yet it is impossible to combine them, satisfactorily, in
