than that between each and the hind lateral eye on its side; 
and a similar relative distance (though not to so great an 
extent) obtains in regard to the eyes of the front row. The 
four central eyes form a quadrangular figure, whose foremost 
side is the shortest, and its posterior side the longest. 
The legs are short and moderately strong; those of the 
hinder pair were wanting; but those of the first are rather 
shorter those of the second and third, while these last two 
appear to differ very little in length; their colour is pale 
yellowish tinged with brown, the femora, genua, and tibie 
being pretty distinctly marked with one or two longitudinal 
reddish-brown stripes, and they are furnished with hairs and 
bristles. 
The palp? are similar in colour and armature to the legs. 
The falces, maxille, labtum, and sternum are similar in 
colour to the legs. 
The abdomen is of a short oval form, broader towards the 
hinder part than in front ; it is of a dull yellowish red-brown 
hue marked with some whitish markings onthe upperside: those 
on the fore part leave a longitudinal tapering central stripe ; 
and those on the hinder part form several ill-defined transverse 
curved lines. 
A single example was contained among the spiders for- 
warded to me several years ago, from Scotland, by Mr. J. W. 
H. Traill. I have hesitated hitherto to describe it as a new 
species, owing to the immaturity of the specimen. It is evi- 
dently allied to P. aureolus, Clk., and to P. cespiticolis, 
Walck. ; but the striped legs appearing to me to distinguish 
it satisfactorily from these species, I now describe it, in the 
confident expectation that, when adults have been found, my 
view of its specific distinctness will be fully confirmed.

An adult male and several adult females were found on the 
22nd of June, 1877, at the roots of star-grass and other 
herbage on the Studland sand-hills. The male being new to 
science, I add here a few notes upon it. 
Adult male, length rather over 14 line. 
The pattern on both the cephalothorax and abdomen is simi- 
lar to that of the female (fully described /. c. supra); upon 
the abdomen, however, it is much obscured by the paler parts 
being ofa slightly sooty-grey hue, caused in some measure by
