lateral) and one dorsal spine at base. Tibi're ii. with two 

 dorsal spines and one lateral one at apex on posterior side ; 

 iii. and iv. with two dorsal spines, one at base, the other at 

 apex. 



Metatarsi without any spines. 



Falces three times as long as the height of clypeus, stout 

 (in male slightly attenuate and divergent at apex) ; basal 

 joint presenting no external striae, but some small setigerous 

 granulations towards apex ; with two separate setiform hairs 

 on inner side in front of each joint. Upper margin of fang- 

 groove bearing two stout sharp adjacent teeth ; lower margin 

 with four or five small teeth. 



Sternum rather longer than broad, slightly convex, set 

 with short hairs. 



Abdomen dull olive-green, clothed with short fine hairs, but 

 with no transverse pale lines and spots.

 (PI. II. fig. 2 a.) 



Epigyne of female presenting a very distinct, deep con- 

 cavity, circular or almost square, and truncate at the posterior 

 margin. The spermathecffi and ducts are conspicuous above 

 the orifice. 



This species can very easily be distinguished ixoxo. pygma^um 

 by its larger size, by the different form of the palpal organs, 

 and by the greater distance of the anterior centrals from the 

 laterals; from oblong um ^ Gh.^hj the spines on femora ii. ; 

 from erransj Bl., by the absence of spines on the metatarsi, 

 and the unicolorous dusky abdomen. 



Taken abundantly, of both sexes, at Hoddesdon, in Hert- 

 fordshire, by F. M. Campbell, Esq., and at Bloxworth, 

 Dorset, by the Rev. O. Pickard Cambridge. Adult in xVpril 

 and May. Males and females were sent to Dr. ]\Ieade from 

 Pelton coal-pits, near Durham, in 1860. They seem to have 

 been conveyed down the shaft amongst the horse-fodder. 

 Once there, they became gregarious and formed a huge web 

 on a co-o])crative understanding, with a joint-stock spinning 

 industry. Dr. Meade gives a most interesting account of tlio 

 habits and circumstances of the capture of these spiders in the 

 * Zoologist ' for August, 1860, no. ccxix.
