The small collection of spiders from the Falkland Islands 

 described below was brought to this country by Mr. Rupert 

 Yallentin, who has been good enough to afford me the oppor- 

 tunity of examining them. 



Connected generically with Patagonia and the Magellanic 

 Region, they are all apparently new species. Gathered as they 

 have been over a period of two years, they comprise only six 

 species of spiders and one Opilio, of Sorensen's genus Sadocus, 

 with a fair number of specimens of some of the species. 



Three of these are Argiopidse which are easily conveyed by the 

 wind, and supply no argument for a former land connection 

 between these islands and the mainland of America.

 Genus Araneus Olerck. 



Araneus vallentini, sp. n. (PL I. figs. 3-3 e.) 



The colour as seen in specimens taken from spirit is as 

 follows : — 



Oephalothorax pale yellow-brown with longitudinal streaks of 

 long white hair, rather bare on the sides but a pale marginal 

 streak all round. Mandibles pale yellow-brown at the base, dark 

 brown at the apex. The fangs are dark brown at the base, 

 dingy yellow-brown at the points.
