,g NOTES ON BRITISH SPIDERS. 



Maxilla short, strong, obtuse at their extremity, and greatly 

 inclined to the labium. 



Labium rather small, broader than high, impressed across the 

 middle and rounded at the apex. 



Sternum large heart-shaped broadly-truncate in front very 

 convex, obtuse at its hinder extremity ; the colours of the maxillae 

 labium and sternum is like that of the falces. 



Abdomen short, oval, nearly globular, black, glossy, furnished, 

 but not thickly, with short hairs. 



Spinners short, tolerably compact ; colulus very distinct, 

 oval, pointed at its extremity. 



A single example of this very distinct little spider was found 

 among moss and lichens by A. W. Pickard-Cambridge, in 

 September, 1898, at Dunlugas, in BanrTshire.

The adult male only was described and figured (I.e. supra.). 

 I now subjoin a description and figures of what I believe to be 

 the female of this species. 



Adult female, length i line. 



In colour, general appearance, and characters this sex is similar 

 to the male, but the caput (as usual) wants the elevation of its 

 upper side ; that part is slightly and roundly raised above the 

 thorax, when looked at in profile, there being a dip between 

 them just behind the occiput. The eyes are on black spots, and 

 form a large transverse oval, broader than long. They are, 

 excepting the fore-central pair, which are much the smallest, of 

 tolerable and nearly equal size. The interval between those of 

 the hind-central pair slightly exceeds a diameter, and is rather 

 larger than that between each and the hind-lateral eye next to it. 

 The central quadrangle is slightly longer than broad, its fore- 

 side being much the shortest. Those of each lateral pair are 

 seated a little obliquely on a strongish tubercle. Taken in two
