REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. . 457 
Legs moderately long, not very strong; colour pale yellow, furnished sparingly with 
hairs, among which are a few more erect on the uppersides of the genual, tibial, and 
metatarsal joints; their relative length is 4, 1, 2, 3. 
Palpi similar to the legs in colour, not very long nor stout ; digital joints suffused with 
brown; cubital joints short, curved, enlarged at their extremities; radials shorter than 
the eubitals, and furnished in front towards the outer side with some strong black bristly 
hairs, giving the appearance of a kind of tuft in some positions; the fore extremity of 
each radial is produced into along narrowish projection, directed obliquely outwards, 
imperfectly bifid at its extremity, and with a sharp-pointed, curved, black, spiny projection 
issuing outwards from beneath, near the bifid portion. Palpal organs well developed, 
prominent, and complicated, with a doubled-coiled black spine beneath and slightly be- 
yond their extremity, and in connexion with some semitransparent whitish membrane. 
Maxille strong, moderate in length, obliquely truncate, and slightly rounded on the 
outer sides towards their extremities, and inclined towards the /abiwm, which is short and 
semicircular. "These parts are of a yellowish brown colour, tinged with olive. 
Falces similar in colour to the cephalothorax, straight, strong, moderately long, much 
inclined to the sternum, which is heart-shaped and strongly suffused with blackish. 
_ Abdomen elongate-oval, rather longer than the cephalothorax, glossy, black, sparingly 
clothed with short hairs. An adult male of this spider was captured among low plants 
in underwood at Bloxworth in July 1863. It is allied to W. borealis (Camb.), W. picina 
(BL) and W. hiemalis (BL), but may be distinguished, not only by the form of the 
cephalothorax, but specially by the structure of the palpi and palpal organs. 
WALCKENAERA IGNOBILIS, n. sp. (P. 57. no. 42.) 
Male adult, length „5 of an inch. : 
Cephalothorax large, broad-oval, pointed in front on the lower fore margin, broadest 
behind, normal grooves slight, but apparent. Caput very slightly elevated in the occi- 
pital region, the surface of which is rounded, and slopes off into the surrounding surface 
imperceptibly, and over in a rounding form to the lower margin of the clypeus, at the 
middle of which this portion is prominent in a somewhat pointed subtubercular form ; 
sides depressed longitudinally towards the junction of the caput and thorax. Colour dark 
rich brown ; the sides under a lens appear finely rugulose; the upper and fore parts of the 
eaput are very polished and glossy, and apparently neither punctuose nor rugulose ; some 
very short strong prominent hairs near and about the eyes; the height of the clypeus is 
less than the distance between the upper and lower pairs of eyes. 
Eyes eight, in four pairs, small, on black spots, those of one pair are seated on the fore 
margin of the occipital elevation, and are distant from each other rather more than one 
eye's diameter; these eyes divide equally the upper surface of the caput looked at from 
above; another pair (the eyes of which are close to each other) are seated below on a 
slight common tubercle; on either side of these, a very little below their straight line, is 
a lateral pair, the eyes of each of which pairs are contiguous, and placed obliquely on a 
common tubercle. The area occupied by the eyes is a transverse parallelogram occupying 
nearly the whole width of the fore part of the caput, the space between the fore lateral
