species will be considered more 

 fully in the appropriate part 

 of this work.^ At present we 

 may <lev()te our attention to 

 the reniarlvable and most in- 

 teresting character of the 

 weh. 



The locations in which 1 

 first discovered the snares, and 

 where afterward I found them 

 to be (juite abundant, had been 

 for several years a familiar 

 and favorite hunting ground 

 for spiders. It illustrates the 

 fact that some of the most in- 

 teresting discoveries that await 

 futiu'e observers may be found 

 near their own well known 

 haunts, and upon ground that

has been often searched by other workers, or even by themselves. 



The first examples of the species collected by me attracted little atten- 

 tion so far as the snare was 



concerned, because 



they seemed to be 



simply a new spe- 

 cies, or the young of an old 

 species of Orbweaver, hang- 

 ing upon the renniants of 

 webs greatly broken by or- 

 dinary wear and tear in cap- 

 turing insects. But the rep- 

 etition of the form, partic- 

 ularly the peculiar character 

 of the open central, struck 

 me as strange. How could 

 the nets of several spiders 

 possibly happen to be twists 

 ed into the same shape, and 

 that shape so strikingly odd 

 as that which I observed ? 

 This caused me to make a

• Dr. Thorell, to whom I sent specimens, has recently written me that he considers my 

 Radiosa quite identical with TheridioHoma geminosuni (L. Kik-Ii), and agrees with ine that 

 on structural grounds alone it may be well ranked with the Urbitolariie.
