a short fork at the end. (PI. 7, Figs. 7, a.) The palpal organ, (PI. 7, Figs. 7, h), is 

 long and somewhat like that of C. canadevsis.

Clubiona saltitans, n. sp. 



Male 3 mm. long. Female 3.5 mm. 



Cephalothorax 1.5 mm. Colour 



pale, less red in alcohol than C. abboti. Eyes 

 of the upper row in line with the front row 

 and covering the whole width of the head. 

 (Figs. 14, d.) Length of mandibles equal to 

 width of head and slightly longer than in 

 abboti. The male palpus resembles that of 

 abboti, but is more slender and the outer 

 process of the tibia has the lower branch 

 one-half longer than the upper. (Figs. 14, a, b.) 

 It has been found at several places near the 



seashore under stones and sticks on the sand. It sometimes jumps when pursued. 

 This species has been confused with C. abboti. In general it is slightly 



larger, paler and more slender, and the tarsus of the male palpus is distinctly 



smaller. The mandibles are slightly longer, but the arrangement of the teeth 



is the same in both species. (Figs. 14, c)

Xysticus acquiescens, n. sp. 



Male 5.5 mm. long. Legs very short, the first and second pairs 7 mm. long. 

 The general colour is brown, the first legs a little darker and the palpi lighter 

 than the rest. The cephalothorax has the light middle stripe much darkened 

 with brown in the front half. The abdomen has the usual markings in pairs, 

 the hinder pairs united into transverse stripes. (PI. 7, Figs. 1, a.) The first and

second legs have the femur, patella and tibia darkly spotted with brow^n, and 

 the tarsus and metatarsus a little lighter. The male palpus has the two pro- 

 cesses of the palpal organ both small, the basal one simple and the distal one 

 narrow at the base and thickened at the end where it curves toward the other. 

 In front of the tw^o processes is a wide, dark brown ridge. (Fig. 15, b.)
