ARACHNIDA 55 



Epeira labyrinthea : Albemarle, James, Narboro, Charles, Chat- 

 ham, Hood, Barrington, Bindloe, Tower, Abingdon, Indefatigable. 

 Cydosa: Albemarle, Narboro, Hood, Indefatigable. 

 Argyrodes : Albemarle, Narboro. 



From these considerations I conclude that the Arachnidan 

 fauna of these islands is more closely related to that of the Cen- 

 tral American region than to that of any other portion of the 

 globe. 



TECHNICAL DESCRIPTIONS. 



Order ARANEIDA. 



Family FILISTATID^. 



FILISTATA FASCIATA sp. nov. 



(PI. I, fig. 15.) 

 Length 5 mm. 



Cephalothorax dull yellowish : legs similar, with not very distinct 

 dark marks on the femora beyond middle, and base and tip of tibia, 

 and on tip of metatarsus ; abdomen dark brown above, with two pale 

 spots at base and four curved pale bands, the intermediate two being 

 barely interrupted on the middle line, none of them reaching the sides, 

 also an indistinct apical spot ; venter rather paler than dorsum, espe- 

 cially at base ; sternum yellowish. Cephalothorax of usual shape 

 (broken and positions of eyes not evident) ; palpi large and heavy ; 

 legs rather short and hairy ; abdomen large ; projecting considerably 

 beyond the spinnerets. 



Two specimens, one young, from Wenman in December. Easily 

 recognized by its banded abdomen and legs. It will fall in F. O. P. 

 Cambridge's genus Filistatoides ; but I do not deem a division of Fil- 

 istata to be necessary.
