452 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
Mr. William Farren, of Cambridge, in Wicken Fen, near that place, in February 1869; 
and I have great pleasure in naming it after my earliest instructor in araneology, R. H. 
Meade, Esq., of Bradford, Yorkshire. This species comes very near to some species of 
Mr Blackwall's genus Veriene, and would group along with W. depressa and others 
closely allied. 
WALCKENAERA FORTUITA, n. Sp. (Pl. 57. no. 37.) 
Male adult, length 2 of a line (or 45 of an inch). | 
This species seems to be nearly allied to W. bicolor (Bl.); but in the absence of any 
examples of that species, or of any figures of its structural peculiarities, I am inclined to 
think it is distinct. The caput, scarcely elevated above the rest of the cephalothorax, has 
. its upper part rounded; the clypeus (which a little exceeds in height the length of the 
space occupied by the two central pairs of eyes) is a little prominent; and a narrow longi- 
tudinal indentation runs backward from each lateral pair of eyes. 
The eyes are rather closely grouped together on the fore part of the caput, where they 
form two transverse rows, the lower one the shortest and straight, the upper one curved, 
the curve directed baekwards; they do not differ greatly in size; those of the front 
central pair are slightly the smallest; those of each lateral pair are seated a little 
obliquely on a small tubercle; the space between those of the hind central pair is a 
little greater than that between each and the lateral eye of the same row on its side. 
The falces are strong, vertical, conical and a little divergent; they are armed with a few 
minute teeth near their inner extremities. The maxille and labium present no devia- 
tion from the ordinary generic type. All these parts, together with the sternum, are of 
a dark brown colour tinged with yellowish. | 
The legs are rather slender and not very long; they are a little lighter-coloured than 
the cephalothorax, and are furnished with hairs; among these are a very few slender 
erect ones, of a bristly nature and of different lengths, on their uppersides; the legs do 
not differ much in their length, which is relatively 1, 4, 2, 3. 
Palpi short, moderately strong and hairy, similar in colour to the legs; the radial 
and cubital joints are of equal length; but the cubital is much the strongest, being 
enlarged at its extremity (chiefly in front and behind); the upper margin of the extremity 
is uneven or irregular, but presents no marked prominenees or projections; the digital 
joint is rather darker than the rest, moderate in size, of oval form, and slightly protu- 
berant near.the base on the inner side. The palpal organs are well developed, rather 
‘complex, and have apparently a slender filiform convoluted spine enveloped in mem- 
brane connected with their surface. | 
Abdomen oval, moderately convex above, slightly clothed with hairs of a blackish 
colour, shining, with some obscure pale markings, and on the hinder part of the upper- 
side some transverse curved lines of the same nature. : 
In colour and general character an adult female differed in no respect from the adult 
male, except that in the former sex the clypeus was rather less in height. O 
| Three males and one female were taken by myself among grass and other herbage near — — 
the Basingstoke Railway Station, Hants, in June 1869. | :
