540 REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 
The falces present no remarkable feature. 
The mazille are strong, strongly curved, and inclined to the labium, which is small, of 
a somewhat quadrate form, rounded at the apex. 
The sternum is heart-shaped, and exceedingly convex. 
The abdomen is glossy and thinly clothed with short hairs; it is of a short oval form, 
and very convex above. | 
A single example was received in the autumn of 1871 from the Cheviot Hills, where 
it was found by Mr. James Hardy. It may be easily distinguished from many other 
similarly coloured and closely allied species by the form of the crescent-shaped process 
at the base on the outer side of the palpal organs, and by other differences in the struc- 
ture of these parts, visible when carefully examined through a moderately powerful lens. 
LINYPHIA RETICULATA, sp. n. (Pl. XLVI. fig. 11.) (Vide note, post, p. 553.) 
Male adult, length 13 line; female adult, 24 lines. 
- In general form and structure this species is of the ordinary type, and is nearly allied 
both to L. pallida, Cambr., L. decens, id., and L. microphthalma, id.; it is, however, 
a much larger spider than either of those species, and differs from all in the structure 
of the palpal organs; the whole of the fore part, including the legs and palpi, is of a 
clear brightish orange-yellow colour; the abdomen is dull whitey-brown, marked with 
a sort of network veining of a paler hue. 
The clypeus is prominent below, but very slightly impressed below the eyes; and its 
height is nearly two thirds of that of the facial space ; there are a few bristly black hairs 
directed forwards in the region of tbe eyes, and in a line along the longitudinal centre of 
the cephalothorax. 
The eyes are small, and seated on black spots ; those of the hind central pair are sepa- 
rated by a space equal to about an eye's diameter, and are nearer to each other than each 
is to the lateral of the same row on its side: those of the fore central pair are very nearly 
contiguous to each other; and each forms, with the two hind central eyes, an isosceles 
triangle, the fore central eye forming one end of its base: those of each lateral pair 
are contiguous to each other, and are seated very obliquely on a tubercle. 
The /egs are moderate in length and strength; their relative length appeared to be 
4, 1, 2, 3, there being but little difference between 4 and 1; they are furnished with 
hairs, bristles, and a few erect very fine spines or spine-like bristles. 
The palpi are slender, the palpal bulb being of moderate size, exceeding in length 
. that of the radial and cubital joints together; the latter of these is bent, of the same 
length as, but less strong than the former, and, besides other bristly hairs, has one larger 
and stronger than the rest, and slightly sinuous, directed forwards near the middle of 
its fore extremity on the upperside: the radial joint spreads rather prominently in 
front, in the middle of which the margin appeared to be of a slightly and somewhat 
obtusely angular form; it is also furnished with bristly hairs, those near the margin 
being the strongest, and placed in somewhat of a row, following the direction of the 
margin: the digital joint is oval, with a strong lobe on the middle of the outer side.
