ON BRITISH ARACHNID A. 69 



A single adult female was received from Mr. W. P. Winter, 

 by whom it was found near the canal between Earby and 

 Gargrave, in the West Riding of Yorkshire, among vegetation 

 under a wall. This spot is quite in the country, so that it is 

 highly improbable that it may have been a foreign importa- 

 tion. M. Simon thinks that it must be an " exotic," but 

 although the importation of foreign spiders often occurs, 

 it has not, so far as I am aware, ever been known to happen 

 in any spot thus far removed from foreign traffic and com- 

 merce. At any rate, even if this should have been the case 

 in the present instance, this spider appears to be undoubtedly 

 a species new to science, and a very remarkable one. 



Araeoneus aequus, sp.n., PI. A., Figs. 11, 12, 13, p. 55. 



Adult female, length 1 line. 



Cephalothorax broad, gradually narrowing to the fore 

 extremity, but with little or no lateral impression at the junc- 

 tion of the caput and thorax. Occiput rather roundly convex, 

 and its profile slopes gradually forwards in an even line to the 

 lower margin of the clypeus, the height of which is about half 

 that of the facial space, and there are several curved hairs in the 

 median line on the hinder part of the caput. The colour is 

 yellow-brown, a little darker on the sides of the caput. 



Eyes small in two almost equally curved rows, whose con- 

 vexities are in opposite directions, or four pairs, those of the 

 posterior row are nearly equally separated ; the interval 

 between the two centrals being perhaps rather the largest. 

 The four central eyes form a square, whose anterior side is 

 much the shortest. 



Legs moderate, and almost equal, in length, colour pale 

 and yellowish, that of the first and second pairs suffused 

 slightly with yellow-brown ; they are furnished with fine 

 hairs, those of the under sides of the femora arranged (as is 

 the case in so many spiders) in two parallel longitudinal 

 lines ; and there is a fine bristle on each of the genual and 

 tibial joints of the two hinder pairs.
