The most prominent species, aside from the Silk-spider, is the 
great brown House Spider (Heteropoda venatoria), which is very 
common. Fig. 206. 
The cosmopolitan species were probably mostly introduced from 
Europe by the early settlers, while the tropical American forms 
were mostly brought from the West Indies. Probably every vessel 
that arrives brings numerous spiders, some of which may easily be 
naturalized. Doubtless there are numerous additional species, not - 
yet recorded from the islands. 
The following species are generally distributed in both hemis- 
pheres : 
Tegenaria Derhami Scop. 
Pholeus tipuloides Koch. (Fig. 212.) 
Theridium tepidariorum Koch; House Spider. (Fig. 213.) 
Theridium rufipes Lucas; House Spider. 
Uloborus geniculatus Olivier. (Fig. 215.) 
Heteropoda venatoria (L.); Great House Spider.* (Fig. 206.) 
Tapinattus melanognathus Lucas; Black Jumping Spider. (Fig. 
222.)
