I.- INTRODUCTION. 



The British Expedition to the Antarctic Continent under the command of the late 

 Capt. R F. Scott, C.V.O., R.N., sailed from England in the early summer of 1910, 

 and on July 26, passing South Trinidad, a rocky island about lat. 20° S. and long. 

 29° W., sent boats ashore to investigate. The small collection of spiders below 

 described was brought back with the other material thus obtained. 



Two specimens from New Zealand were also taken on the return journey in June 

 and October, 1912. 



Unfortunately, nearly one-half of the specimens have not reached maturity. This 

 renders their determination uncertain, and cousec^uently precludes any clear indication 

 of the source from which the fauna has had its origin. The island is situated in the 

 belt traversed by the south-east trade winds, and the families are mostly those whose 

 members are carried long distances l)y the aid of the wind. 



The following is a complete list : — 



From South Trinidad. 



Uloborus geniculatus, Oliver 

 Tetragnatha 1 ferox, L. Koch 

 Meta 1 flava, 0. P. Cambr.
