Mr. BrackwaLvs Descriptions of new Species of Spiders. 647 
Length of the female j'5th of an inch; length of cephalo-thorax ++; breadth 
35; breadth of abdomen zr; length of an anterior leg 3; length of a leg 
of the third pair 4^. 
Cephalo-thorax oval, convex above, glossy, with an indentation in the medial 
line of the posterior region. Mandibles powerful, conical, armed with 
teeth on the inner surface, and inclined towards the sternum, which is 
heart-shaped. Maxillæ strong, and inclined towards the lip, which is 
semicircular and prominent at the extremity. "These parts are brownish 
black. Legs slender, and of a pale reddish brown colour; first and fourth 
pairs the longest and equal in length, though, as in numerous other in- 
stances, the latter limbs do not extend so widely as the former, in conse- 
quence of being articulated nearer to each other, third pair the shortest. 
Palpi of a dark greenish colour. Abdomen slender, oviform, projecting 
a little over the base of the cephalo-thorax ; it is thinly covered with 
hairs, and brownish black. Plates of the spiracles very dark brown. 
The male resembles the female in colour, and in the relative length 
of his legs, but his mandibles and maxillæ are tinged with red, and the 
former have a small process in front, near the articulation of the nail. 
The second joint of the palpi has a row of hairs, directed forwards, ex- 
tending along its upper part; third and fourth joints short; the latter, 
which is much the stronger, is slightly elongated in front, and bas a small, 
pointed projection on the outer side, near its extremity ; fifth joint some- 
what oval, having on the upper part a bold prominence, indented on the 
outer side, and a curved, conical protuberance on the inner side; it is 
convex and hairy externally, concave within, comprising the palpal organs, 
which are prominent, highly developed, complicated in structure, and of 
a dark reddish brown colour. 
Adults of both sexes were captured on rails at Capel Garmon, in Denbigh- 
shire, and at Crumpsall Hall, near Manchester, in the autumn of 1836. 
34. Neriene parva. Mas brunneus; abdomine saturatiore. 
Length of the male 35th of an inch; length of cephalo-thorax 355; breadth 
dg; breadth of abdomen 35; length of an anterior leg yg; length of a 
leg of the third pair +5.
