which the base of the cephalothorax appears to fit. The abdomen is sparingly furnished 
with hairs, and is of a dark black-brown colour, spotted above with white; four of these 
spots are the most conspicuous, and (on the centre of the upperside) form an oblong 
figure, whose fore side is the shortest. The colour of the rest of the spider is a dull 
yellow brown, except the tibiæ of the legs, which are dark, the digital joints of the 
palpi, which are still darker, and the us ix of the cephalothorax, which are strongly 
suffused with reddish brown. 
The falces are long, strong, TON and divergent; their surface is rugose; and 
they are armed on their inner sides with two strong prominent teeth; the hinder one of 
these greatly exceeds the other in size, and has a small tubercle (or small blunt tooth- 
like prominence) near the middle of its fore side. 
The fangs are long, strong, and slightly bicurvate, and with a shallow toothlike eleva- 
tion on the middle of their inner sides. 
This fine spider may be readily distinguished from any hitherto recorded Neriene, both 
by its size (being 1% line in length) and by the highly developed falces and white spotted 
abdomen, by which latter characters it differs also notably from the Drepanodus obscurus 
of Menge, to which in other respects it seems very closely allied. 
À single adult male was found by myself at Bloxworth, running very swiftly among 
short grass in a damp place at the beginning of May 1870, and another in June 1871. 
The proximity of many spiders of the genus Neriene to the Drassides has not escaped 
the attention of araneologists ; and the present species is one in which the affinity is very 
Observable; in its general appearance while alive and running, it had a peculiarly Drassi- 
form appearance. 
NERIENE LUCIDA, n. sp. (Pl. XXXV. no. 27.) 
Male adult, length barely 1 line. 
The cephalothorax (which is margined with black), the falces, maxille, labium, and 
sternum are of a dark, blackish, shining brown. 
The /egs and palpi (except the radial and digital joints, which are dark, the latter being 
nearly black) are of a bright orange-yellow colour, the palpi being of a rather duller hue 
than the legs. 
The abdomen is jet-black, glossy, and sparingly furnished with hairs, and has four 
tolerably conspicuous impressed dots or punctures on its upperside, at about the centre 
of which they form nearly a square. 
In size, form, and colour this spider nearly resembles many others of this group, and 
may be best distinguished by the form of the radial joints of the palpi and the strue- 
ture of the palpal organs. 
The caput is not raised above the level of the thoracic portion of the cephalothorax ; 
and a single longitudinal row of (not very long) bristly hairs occupies the median line of 
the eaput and thorax. 
The eyes are in the usual four pairs, or two curved rows, the curves slight, and directed 
away from each other, thus forming a narrow oval figure; they are rather small, and do
