Arachn. B. ii. p. 10. tab. 40. fig. 101) among the synonyma of 

 the above species, as there appears to be much uncertainty about 

 its identity. M. Walckenaer has added the Clubiona pallens of 

 M. Koch to the synonyma of Clubiona amarantha (Hist. Nat. des 

 Insect. Apt. t. ii. p. 478), supposing it to be the latter species in 

 an immature state, for he remarks that " c'est une jeune que 

 M. Koch a decrite;" this, however, is a mistake, as it is a 

 smaller and perfectly distinct species, and M. Koch's figure of 

 the male clearly represents an individual with the palpal organs 

 fully developed.

Two adult females of this handsome Theridion were received
