pale yellow and gray. The cephalothorax is dark in the middle 

 and light at the sides, with light gray spots over the coxa;. The 

 dark middle area extends forward between the eyes to the front 

 edge of the head, dividing into two below the ej'es. The mandibles 

 are striped on the front with black. The abdomen is light at the 

 sides, and the middle dark marks are united into a broad stripe 

 with irregularly indented edges. The legs are marked with broken 

 dark rings, the femur and the tibia having parts of four rings each. 

 The sternum is dark around the edges, and the whole under side 

 of the abdomen is gray, darkest at the sides, with two indistinct 

 light lines converging toward the spinnerets. The tibia of the male 

 palpus is as short as the patella. The process of the tibia is as 

 long as the diameter of the joint. It is flat and widened at the 

 end, hollowed in at the. middle, and with the corners sharp, and 

 sometimes two little teeth in the hollow. The palpal organ resem- 

 bles that of the other species. 



A female just moulted, from Three Mile Island, Lake Winni- 

 pesaukee, N. H., May 25, 1905. Cephalothorax 6.5 mm. and abdomen 

 the same length; fourth and first legs 24 mm. Colors and markings 

 like those of male. The epigynum resembles that of D. idoneits 

 with the middle portion not as prominent, and the pockets at the 

 sides more open.

 and several males made their last moult. They were under stones 

 and loose boards lying on the ground near the shore. 



Oxyopes scalaris (Hentz) Em. 



This species was found again at Durham, N. H., in June 1904. It 

 resembles closely a species found commonly on the Pacific Coast 

 from British Columbia to California.

 figures 1 to le.) 

 2.5 mm. long, pale and translucent, with black spots on the head 

 and legs and around the sides of cephalothorax and abdomen.. The 

 cephalothorax is as wide as long, and almost circular. The eyes 

 are on the top of the head in two nearly straight rows, the front 

 row shorter than the upper, and the front middle eyes farther apart 

 than they are from the lateral eyes. The upper middle eyes are 

 not round but irregularly oval, largest from front to back. The 

 head extends forward a little beyond the eyes, and under this
