Duriiio- the siunnier of 1001, Mr. E. A. Schwarz uiid Mr. H. Barber 

 collected extensively in parts of Arizona, especially in the vicinity of 

 Williams. In the following pages is a list of the Arachnida that the}^ 

 collected. In a previous paper^ I have reported on a collection made 

 by Mr. Schwarz in southern Arizona. There is, however, veiy little 

 similaritv in these two collections. The one made during the past 

 summer contains a great man}' northern species; in fact, a large major- 

 ity of them occur in Colorado. 



In this list there are recorded til spiders and 13 other arachnids, a 

 total of 77 species. In the previous article there were 5.5 species, 87 

 of which are not found in this list; this makes the total number of 

 arachnids recorded from Arizona 114. 



Of the spiders in this list the Attidte are represented by 13 species, 

 the Thomisiidie by 12 species; none of the other families have more 

 than 8 species. Three species are described as new. 



This material forms part of the collections of the United States 

 National Museum.
