and are a little divergent at their extremity ; and the eyes of the hind row are equidistant 
from each other; the maxillee also appear to be less inclined towards the labium than in 
N. pallipes. The palpal organs have a strong curved corneous process at their base on 
the outer side, closely adhering to them ; and the abdomen is rather more perceptibly 
clothed with fine hairs than that of N. pallipes. An adult male was beaten from a furze- 
bush at Bloxworth in the summer of 1863. 
LINYPHIA ? OBLONGA, n. sp. 
Female adult, length 25 of an inch. 
In general form this spider is of a flattened oblong, the abdomen being rather broader 
behind than in front; and in its mode of running the whole body is kept very closely 
adhering to the surface upon which it runs. 
The cephalothorax is of a pale yellowish brown colour and semitransparent. The 
normal grooves and indentations are visible, but not strongly marked ; and there is a very 
slight depression at the junction of the caput and thorax; the height of the clypeus is 
greater than the space occupied by the four central eyes. 
Eyes very small, not differing much in size; they are seated on small black spots, and 
are all of a pearly-white colour; the two central ones of the hinder row are nearer 
together than each is to the end one of the same row on its side; the fore centrals are 
close together, and those of each lateral pair are very obliquely placed on a small 
tubercle; the space between the hind centrals is about equal to that between each and 
the fore central opposite to it. 
Legs rather long, slender; relative length 4, 1, 2, 3; they are furnished with hairs 
and a few slender spines, and are of the same colour as the cephalothorax, the tibiæ and 
metatarsi being sometimes suffused with yellow-brown. 
Palpi moderately long, similar in colour and armature to the legs. 
Falces moderately long, powerful, inclined to the maxillz, and similar in colour to the 
cephalothorax ; no teeth could be discerned on their inner surface. 
Maaille strong, rather inclined to the labium, which is short and semicircular; these 
parts, as well as the sternum, are also similar in colour to the cephalothorax. 
Abdomen oblong, longer than the cephalothorax, over which it projects a little, flattish 
above, rather broader behind than in front, of a dull greenish yellow suffused with black 
brown, marked somewhat regularly with pale lines and spots, similar to those in many 
species of Neriene (Bl.), but, like them, these markings are chiefly visible when in spirit 
of wine; itis glossy, and very slightly clothed with a few fine hairs; the underside is 
less suffused with black brown than the upperside. The sexual organs are not very 
prominent, but conspicuous by being marked, and their apertures margined, . deep 
red brown; the aperture is small, and nearly round in form. 
Adult females of this spider (considered to be a Linyphia by Dr. Koch) are not infre- 
quent in May and June upon iron railings at Bloxworth, Dorset ; it may easily be dis- 
tinguished from most other species by its oblong flattened form, as well as by the 
minuteness of its eyes, and (which is also unusual) the fore central eyes being of a pearly- 
White colour like the rest, I have not yet succeeded in detecting the male, which, when
