ARANEIDEA.

The eyes occupy a larger area, and are of a pale, dull, yellowish-brown hue, being much 
paler than in the other species mentioned. 
The legs are rather shorter in proportion, and are pretty distinctly annulated with brown ; 
whereas they have rarely any trace of annulation in T ruricola. 
The abdomen is of a much darker hue, being of a blackish yellow-brown colour, the 
normal median longitudinal marking on the fore half of the upper side is of a brighter orange- 
yellow, and is margined by a much more distinct black border. The form of the genital 
aperture differs but very slightly. The under side of the abdomen is suffused with dark brown, 
and on each side is a marginal border of a darker black-brown.

103. — Trochosa adjacens, sp. n. 
Adult female : length just over 5 lines. 
This spider is very closely allied to T. terricola, Thor., differing from it in about the same 
degree as T. propinqua does from T. ruricola, De Geer. It is rather a smaller spider, and 
the cephalothorax appears also to be of a rather broader form, and the whole spider is of a 
much duller hue and less distinctly marked ; the bands on the cephalothorax are scarcely 
discernible ; the whole being of a dull yellowish-brown colour, pretty densely clothed with 
short, greyish-sandy pubescence, and with some indistinct, darker brown, radiating stripes 
indicating the normal indentations. 
The eyes of the front row are much larger than in T. terricola, and are very nearly 
equal in size to those of the hinder row ; these last, however, being much smaller than the 
corresponding ones in that species. 
The legs in the present spider have no trace whatever of annulation, while those of 
T. terricola are frequently annulated with brown, though never very distinctly, and, in 
general, chiefly on the femora. 
The markings on the abdomen are very similar, as also is the form of the genital aperture, 
though a slight difference in this respect is observable.

Adult female : length 10 lines. 
The cephalothorax of this fine spider is strongly compressed laterally on the margins 
of the caput, and the lateral slopes are much depressed ; the caput, however, is broad at its 
lower margin and tolerably massive above. Its colour is reddish yellow-brown, totally 
obscured by a dense clothing of short, pale sandy-grey pubescence, leaving but very slight 
and broken traces of the ordinary radiating indentations of a darkish brown colour. The 
height of the clypeus is equal to the diameter of one of the fore-central eyes. 
The eyes are in the ordinary position, and occupy an area whose length and breadth 
are, as near as possible, equal ; the front row is distinctly longer than the middle one ; its 
central pair of eyes are much larger than the laterals, though distinctly smaller than those 
°f the hinder row, and are separated by an intei'val less than a diameter, but double as great 
as that which divides each from the lateral next to it ; those of the middle row are divided
