544 REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 
NERIENE CLARA, sp. n. (Pl. XLVI. fig. 14.) 
Female adult, length 12 line. 
In size, general form, and structure this species is nearly allied to N. pudens (infra) ; 
it is, however, a much more richly coloured spider, the cephalothorax being of a deep 
rich shining black chestnut-brown, the legs rich orange, and the abdomen olive-tinged 
black; the latter is rather less obtuse or cylindric in form behind; the hollow (in 
the profile line) between the occiput and thoracic junction is less; and the clypeus, 
which little, if at all, exceeds half the height of the facial space, is less prominent ; on 
the sides and towards the hinder part of the thorax are some indistinct rugulosities and 
impressed dots or punctures, a few of which last may be seen also on the sternum, which 
is convex, shining, and similar in colour to the cephalothorax. 
The eyes form a more regular oval, and are closely grouped ; those of the hinder row 
appeared to be equidistant from each other; those of the foremost row are all very 
near to each other, those of the fore central pair being the nearest together (but not 
quite contiguous), and each is distant from the fore lateral on its side only about half 
the diameter of the former. Those of each lateral pair are a little obliquely placed on a 
slight tubercle, and the fore ones are the largest of the eight. 
The legs are moderately long, and rather strong; the tibiæ of the first two pairs 
appeared to be stronger than usual in proportion to the size of the metatarsi. They are 
furnished with coarsish hairs and a few fine erect bristles. 
The form of the genital aperture is transverse oval; it has a strong rather closely 
applied and somewhat shell-shaped epigyne connected with its fore margin, and directed 
backwards. 
A single example was received in October 1871 from Mr. James Hardy, by whom it 
was found on the Cheviot Hills. 
NERIENE PUDENS, sp. n. (Pl. XLVI. fig. 15.) 
Female adult, length 1} line. 
In general form this spider is rather elongate, the abdomen being oblong-oval, and 
somewhat abrupt and bluff at its hinder extremity when viewed in profile; the cephalo- 
thorax from the same point of view is hollow between the occiput and the junction of 
the thoracic segments ; and the clypeus is slightly hollow beneath the eyes, and prominent 
at itslower margin; the height of the clypeus is less than two thirds, but more than one 
half, of that of the facial space. 
The eyes are on black spots ; they are rather large, not greatly unequal in size, and are 
in the ordinary position; those of the hinder row are equidistant from each other; 
the line formed by the two hind centrals is less in length than that formed by each 
of them and the fore central opposite to it. The two former are separated by rather 
less than an eye's diameter. The fore centrals are very nearly contiguous to each other, 
and each is only about half its diameter separated from the fore lateral on its side ;
