Collected by the Barbados-Antigua Expedition 
from the University of Iowa in 1918

During the spring of 1918 Dr. Dayton Stoner of the Univer- 
sity of Iowa collected some spiders at Antigua and Barbados. 
Many of them are forms common throughout the West Indies 
and South America, but six have been found to be new species. 
A few immature specimens cannot be identified, and three 
specimens which are represented by only one sex have been left 
with only a generic determination. Of the twenty-nine species 
of spiders, nine families are represented. The Argiopide has 
nine species, the Clubionide six, the Salticide four, and the 
other families are represented by but one or two species each. 
The types have been placed in the Museum of Comparative 
Zoology at Cambridge and the paratypes and remainder of the 
collection in the Zodlogical Museum at the University of Iowa. 
Very few spiders have been collected at either Antigua or 
Barbados. In 1878 Becker described Lycosa (Tarentula) beckeri 
and two years later Keyserling described from the same col- 
lection Sparassus antiguensis, a spider that since has been found 
at Hayti and Porto Rico. 
The arrangement in families and genera follows Simon’s 
‘‘Histoire Naturelle des Araignées’’ and Petrukevitch’s ‘‘Index- 
Catalogue of Spiders of North, Central, and South America,’’ 
American Museum of Natural History, Bulletin 29, 1911, except 
the Walckenaer names based on Abbot’s unpublished drawings.
