tances apart, and the whole group of eyes wide in proportion to 

 the width of the head. The abdomen is oval and slightly indented 

 in the middle. The colors arc all dark, and were not noticed when 

 the specimen was fresh. The cephalothorax is of the usual brown, 

 and the legs the same color with the ends of the first and second 

 pairs lighter. The abdomen seems to have been lighter in front 

 of the depression, but there are no distinct markings to be seen in 

 its present condition. The male palpi have no process on the tibia. 

 The palpal organ is prominent as in quinquenotata.

This species lives in sandy places, sometimes in company with longi- 

 pes, which it resembles in color and habits. It is smaller than longipes, 

 measuring 4 mm. in length, the cephalothorax between 1£ and 2 mm. 

 in length. The cephalothorax is shorter and the head narrower than 

 in longipes and the lateral eyes are nearer the middle pairs, Fig. 1 a. 

 The sternum and the legs are slightly shorter than in longipes. 



The legs and cephalothorax are light orange brown, with scattered 

 shining hairs of the same color. The abdomen is covered with 

 iridescent scales, yellow in front, and darker toward the hinder end. 

 The colors vary in different individuals and some are greenish gray 

 as in longipes. There are two pairs of white spots on the abdomen, 

 one pair in the middle and another at the front end, and just behind 

 the front pair is a middle white spot of about the same size, Fig. 1. 



The epigynum differs little from that of longipes, but is usually 

 less regular in shape. The male palpi also are like those of lon- 

 gipes with a similar process on the tibia, Fig. la. 



This species is common on the sand dunes at Ipswich, Mass., 

 among the roots of sand grass. It matures about the first of June, 

 when both sexes are active, running about on the sand from one 

 bunch of grass to another, or hiding under any loose object lying 

 on the ground. The cocoons which are found early in June are 

 white and thin, and contain about eight eggs. 



In pairing the male holds the female by the first and second 

 legs around the thorax between her third and fourth, reaches his 

 head under her and inserts the palpus of the same side as the 

 clasping legs, Fig. 1.

 figures 3 to 3d.) 

 Mature males and females have been found from the middle of 

 May to the first of July at Portland, Me., and at Monhegan, Me.
