domen, the last of which is sometimes continued on the back in 

 the form of a band. It is common in the Southern States, and 

 is well known, as the people there believe its bite is very pois- 

 onous. That spiders are all supplied with a poisonous fluid 

 conveyed in their fangs, there can be no doubt ; but I cannot 

 assert that this is more dangerous than another, for persons 

 who do not study Natural History are apt to confound objects of 

 a different nature. A respectable physician, however, pointed 

 out this species to me as the one, and told me that in every 

 instance he could arrest the violent symptoms arising from its 

 bite by inducing a reaction in the system, and frequently had 

 produced instant relief with a glass of brandy. Most species 

 of this genus are the common prey of the several species of 

 Sphex called dirt-daubers in the South, on account of their 

 making clay nests, in which they enclose with their progeny 

 from twenty to thirty spiders, which serve as food to the young 

 larvas. 



Pholcus, (Walck.). 



Eyes 8, PI. 17, fig. 7 ; legs very long and slender, 1. 2. 4. 3. 

 lingua short, triangular ; maxilhe long, inclined over the lingua. 

 Making a loose web. One species. Inhabiting the ceilings of 

 houses. I seldom met with it at a distance from the Atlantic 

 coast. [104] 



Linyphia, (Latr.). 



Eyes 8, PI. 18, figs. 23, 24 ; legs 1. 274: 3. lingua short, tri- 

 angular; maxilhe short, wider above. Making a horizontal web 

 on bushes, with another one surrounding it above and below, 

 constructed of threads crossed in every direction, as that of 

 Theridium. The spider holds itself downward, under the 

 horizontal web. Five species, all small. 



Te;tragnat]ia, (Latr.). 



Eyes 8, in two rows nearly parallel ; legs very long and
