RELATIONSHIP OF THE FAUNA. 93 



Uhler calls attention to the significant fact that two of the 

 Pseudoneuropters, Mesothemis longipentds and Ledes unguicidata, 

 are freshwater types, whose larval condition is dependent 

 upon the existence of fresh, or but mildly brackish, waters. 

 The Bermudian earwig {Labidura riparia — Forficula gigantea) is a 

 species recently introduced into the Eastern United States 

 from the Mediterranean region. 



Prior to 1888 there were but six species of spiders recorded 

 from the Bermudas, of which three were described as peculiar 

 by Blackwall — Salticus diversus, Xysticus pallidus, and Epeira 

 gracilipes. To this number we now add eleven additional 

 forms, one of which, Lycosa Atlantica of Marx, proves to be 

 new. Dr. Marx, of Washington, has kindly determined all 

 of our forms, and his notes on species appear on another page. 

 The thirteen species which are not peculiar to the Bermudas 

 are the following : 



Loxoscdes rufescens, . W. Indies, Florida, Europe, Asia, 



Africa, Madeira, Canaries, Cape

 Heteropoda venatoria, . Cosmopolitan.
