Note. — The females of the other species may be easily distinguished by 

 the characters given for the males. 



Porrhomma errans^ Blackw. (PI. II. tig. 1.) 

 {N. and L. errans, Bl. & Cb.) 



Length of male 1 line ; female H line. 



Cephalothorax and legs similar in colour to those of Meadii, 

 and also in other general respects. 



Eyes. — Posterior row straight, centrals one diameter apart, 

 two diameters (or almost) from laterals ; anterior row straight, 

 centrals scarcely smaller than laterals, one and a half (or 

 scarcely) diameters from laterals, one half from each other. 



Legs. — Femora i. with two s[)ines, sometimes three, one

This species, while readily distinguishable from ^feadn'f 

 ohlonguniy and pggmcvum by the single metatarsal spine, yet in
