est on the under sides of tlie legs. The sternum is black ai'ound the 

 edge, and the abdomen has irregular black spots at the sides and 

 beneatli. The abdomen of the female is large and oval, slightly 

 pointed behind. Tlie epigynnm is small, opening by deep notches at 

 the sides of the short and wide middle lobe. The male is very much 

 like the female, but the abdomen is smaller and the three teeth on 

 the front of the mandibles are larger. The pal))al organs are large 

 and long, with three prominent spines at the end. Figs. 1^>, Ic. The 

 tarsal hook is flat and wide, and the forward corner of the base runs 

 to a shai-p point. The tibia is slightly widened at the end, and has 

 several large hairs on the inner side. 



This species lives under stones and logs, and I have occasionally 

 found it under leaves in woods in winter. Salem, Mass.; Providence, 

 R. I. ; and New Haven, Conn. It is also a common European species. 



Diplostyla. 



Stylophora Mcnge. 



These spiders resemble Bathi/phaiites, except in their copulatory 

 organs. They are all small spiders, living under leaves and low 

 plants. The tarsus of the male palpus is long and the tube of the 

 palpal organ extends outward to its truncated tip, where the tube is 

 coiled in a flat s]>iral. PI. XX. The tarsal hook is large and 

 curved forward. The tube is supported by several strong pro- 

 cesses near its base, and has a soft fringed appendage near its tip. 

 The epigynum has two large openings, between which two soft 

 appendages project backward.

This spider is about 2"5"'"^ long. Cephalothorax and legs yellow- 

 brown. Abdomen black or dark gray, with five or six transverse 

 light markings, usually in the male and sometimes in the female, 

 broken into pairs of spots. The epigynum has long flexible processes, 

 one from the upper and one from the under edge. The openings are 

 at the base of these processes. Figs. 2c, 2d. The tarsus of the male 

 palpus is truncated at the end and slightly narrowed in the middle. 

 The tai'sal hook is long and conspicuous. It is bent in a short curve 

 at th.e end and is widened at the tip. The tube and one of its 

 large appendages are twisted in a circle round the end of the tarsus,
