rence. The vulva is formed by a tolerably large, rounded, brownish 

 area, which immediately in front of the rima genitalis exhibits two 

 small black spots, and moreover, in front of these, two larger dark 

 spots, which however are not so sharply limited and less distinct.

The palpi of the cf of this species much resemble those of C. 

 lutescens, but the large process of the tibial joint is more pointed, 

 and it is from the under side of the base of that process, and not 

 from the apex of the tibial joint itself, that the second process goes 

 out, which here has the form of a sharp tooth curved and directed 

 forward. — Through the kindness of Mr Cambridge I am in possession of 

 a "C. amarantha Blackw." That this species with its small dimensions 

 and short mandibles cannot be identical with C. amarantha Walck., 

 which is stated to be 5 Paris lines long, and to have the mandibles 

 "as long as the cephalothorax' 1 (vid. sup., p. 215), appears to me self- 

 evident. — The female is unknown to me.

Although the name Clubiona erratica was long previously given 

 by Walckenaer to quite a different spider, Chiracanthium carnifex 

 (Fabr.) C. Koch (= Club, erratica Blackw.), which C. Koch, when 

 he first described Ms C. erratica, erroneously supposed to be identical 

 with it, the specific name erratica may, it seems to me, be retained
