REV. O. P, CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 541 
The palpal organs are highly developed, prominent, and complex, and of a dark 
reddish-brown colour: it is impossible accurately to describe these so as to distinguish 
them from the same parts in other closely allied species; but a striking difference may be 
seen in comparison, and this it has been endeavoured to show in the figures given. 
Falces long and powerful, prominent near their base both laterally and in front; five 
sharp teeth of different lengths arm the inner sides of their extremities, which are a little 
divergent. 
The maxille are strong, massive, and inclined towards the labium, those of the male 
being more inclined than those of the female; in the former their extremities are nearly 
contiguous. 
The Zabiuwm is short, broad, rounded at its apex, and transversely impressed across the 
middle. 
The abdomen is of an oval form, and thinly clothed with hairs. 
The female resembles the male in colour and general structure, and is remarkable 
from the long, prominent process or epigyne connected with the genital aperture and 
directed backwards; in this it resembles L. insignis, Bl., and some others; but a differ- 
ence is easily seen on comparison; the abdomen also of the female is larger and more 
convex above than that of the male. 
Adults of both sexes of this distinct and interesting spider were forwarded to me in the 
autumn of 1871 by Mr. James Hardy, by whom they were then lately found on the 
Cheviot Hills. 
Genus NERIENE (Bl.). 
NERIENE SYLVATICA. 
Neriene sylvatica, Bl. Spid. Gt. Brit. and Ir. p. 254. 
Bathyphantes setipalpus, Menge, Preuss. Spinn. p. 124, pl. 23. fig. 48. 
Erigone sylvestris, Westr. Ar. Suec. p. 327 ; Thor. Syn. Europ. Spid. p. 134. 
Adult males of this species (of which the synonymy has been satisfactorily determined 
by eomparison of English, Swedish, and German specimens) were contained in the 
Cheviot-Hills collection received from Mr. J. Hardy in the autumn of 1871. 
NERIENE CONIGERA. | 
Neriene conigera, Camb. Zoologist, 1863, p. 8583; Id. Linn. Trans. xxviii. p. 450, pl. 34. no. 17. 
Adult males and females of this spider were found near Newhaven, Sussex, in June 
1871, by both M. Eugéne Simon and myself; these examples having been longer in the 
adult state than those referred to loc. cit. suprà, were much darker- and brighter-coloured. 
'The females resemble the males in this respect. 
NERIENE (DREPANODUS, Menge) ALBIPUNCTATA. 
Neriene albipunctata, Cambr. Linn. Trans. xxviii. p. 451, pl. 34. no. 15. 
A second example of the adult male of this spider was found by myself in the flower-
