Class ARACHNIDA. 



Obs. The spiders were examined immediately after 

 they had been removed from the spirit in which they 

 were preserved. 



1. Dysdera erethryna? Walck. 



Hahn, Arachniden, vol. i. p. 7* pi. 1. f. 3. 



The characters of this spider so nearly agree with 

 Hahn's figure and description of Z). erethryna, that I 

 have little hesitation in referring it to that species, not- 

 withstanding the great distance, in point of locality, 

 between the two individuals. Hahn's spider is found 

 in Spain, France, and Germany. 



2. Theridion Backii (n. s.), Nob. 



Villosum ; thorace subcirculari, rufo : pedibus rufis, 

 fusco annulatis, setisque undique obsitis; pari primo, 

 secundo, et quarto longioribus, subsequalibus ; tertio 

 cseteris breviori : abdomine globoso, saturate fusco. 



This species has considerable resemblance to the 

 female of Hahn's T. quadri-giittatam (pi. 21. f. 64.), 

 but is larger, and in other respects decidedly distinct, 

 I have named it in honour of Captain Back. 



2. Tetragnatha extensa (var.), Walck. 



SchcefF. Icon. Insect, pi. 113. f. 9.
