Araneida from the swedish expedition through 

 the Gran Chaco and the Cordilleras.

ALBERT TULLGREN. 



With 10 plates. 



The following pages contain descriptions on some species 

 of araneida brought home by tlie Swedish Expedition to Ar- 

 gen tine and Bohvia in the year 1901 — 1902 and nearly all of 

 which are coUected by Baron Erland Nordenskiöld, the lea- 

 der of the expedition. As far as I know only some few spi- 

 ders are before known from the Gran Chaco and therefore 

 the greatest part of the species seem to be new for science. 

 The whole collection contains a large number of specimens 

 especially of larger species, but many of them are of young 

 indeterminable forms. The most species are collected at Ta- 

 tarenda in Bolivia, a little place within the woodland coun- 

 try. Another place is Quinta in the province Jujuy in Ar- 

 gentine, which is situated in the primeval forest along the 

 Sierra Santa Barbaras. The other localities are Salta, a little 

 town in North- Argentine and Moreno, situated about 3,500 

 m. a. the sea on the table land in the province Jujuy.
