Araneides of the United States. 23 
time. The anterior spine is sometimes much longer and 
white. Dr. T. W. Harris, of Massachusetts, sent me one 
specimen with only thirteen spines. ‘The cheliceres are very 
short and stout in this species. 
Habitat. The United States. 
42. EPEIRA CANCER. 
Plate III. Fig. 13. 
Description. Black ; disc of the abdomen yellowish with 
black dots, circumference with conical black spines. 
Observations. This little spider, described or rather de- 
lineated by Audubon in his Ornithology, makes perpendicular 
webs and is not rare in the south, but was never seen in the 
north. ; 
Habitat. South Carolina. Common in South Alabama.

43. EPEIRA CAUDATA. 
Plate III. Figs. 14, 142, 14b. 
Description. Female, pale testaceous ; cephalothorax 
piceous; abdomen with a conical projection behind, with 
many variable markings ; joints of the feet tipped with dusky. 
There are also two tubercles on the disc of the abdomen 
Which become obsolete in many, probably when the body i is 
full of eggs. 
Male, rufous ; cephalothorax piceous ; abdomen with two 
White dots and a white band above, which are wanting in 
some, and two white dots underneath ; tip of anterior thighs 
black.

and the difference between the sexes, had caused me to de- 
scribe three species which must be referred to one. It makes 
a vertical web, on which it attaches its cocoons in a row, some- 
times as many. as five in number. These are of a brownish 
color, elliptical, and covered with the remains of the insects
