ARACHNIDES— ARANBIDES— EETITELARI^. 71 



Ero with live each ; Linyphia with three, Corynites and Erigone with two, 

 and Anandrus,^ Clya, Dielacata, Euryopus, Flegia, and Schellenbergia with 

 one each. Flegia, Corynitis, Anandrus, Thyelia, Clya, Dielacata, and Schel- 

 lenbergia are all peculiar to the Tertiaries, Schellenberi^-ia to Oeningen, the 

 others to amber. Nearly all the species are from amber, but beside the 

 Schellenbergia from Oeningen there is a species of Erigone and two of 

 Linyphia from Rott, and two species of Theridium from Oeningen as well 

 as another from Aix. 



America, however, does not bear her proportionate share in this repre- 

 sentation, being poorer even than the stratified deposits of Europe, whereas 

 in every other group it is either better represented or falls short by only a 

 single species. There is a single species of Linyphia, two of Theridium, 

 and some egg-cocoons referred for convenience to the comprehensive genus 

 Aranea. That two of the three species known in the perfect state should 

 belong to the genus most highly favored in the European Tertiaries is a 

 point worth noting. 



The family is best represented in Europe (especially in the Mediterra- 

 nean district) and Avarni temperate America, but a few have been found in 

 the East Indies. (November, 188L) 



Gourret, in his recent investigation of the spiders of Aix, found but a 

 single species of this family among the eighteen Araneides described by 

 him. He referred it to Ariamnes. 



ARANEA Linnt^. 



Under this broad generic name are placed notices of some egg-cocoons 

 which are like those made by species of this group and which have been 

 found at no less than three distinct localities. I am not aware that any 

 such remains have before been noticed.

Among the stones obtained by Mr. Dawson in British Columbia are 

 several containino' the flattened remains of the eo'o'-cocoons of Araneides. 

 There are no less than eight of them, of different shapes and sizes, occurring 



' Anandrus is credited with one species, but it is not described (Menge, Lebenszeiclien, etc., p. 7).
