 the relative length of their posterior spinnerets. Nor can it be 

 a Clubionid because its anterior spinnerets are not close together, 

 but far apart.

Figure 5. — Palccodrassus ingcnmis (Scudder). Specimen No. 13520 (83). 

 Legs : a. first left ; b, second right ; c, third right ; d, 

 fourth left, x 10. 



The legs of this species are represented in our textfigure 5, the 

 first and fourth being left legs, while the second and third right 

 legs. It will be noticed that there is a distinct scopula on the 

 first and second tarsi and metatarsi, a condition qtiite common 

 among Drassids. There are three distinct spines on the under- 

 side of the first and second tibia, one of these close to the base, the 

 other two forming a pair a little beyond the middle of the joint. 

 There are also two or possibly three spines on the imderside of 

 the first and second metatarsi, and a pair of spines on the under- 

 side of the first and second fenuu* close to the apical end of the 

 joint. The spines on the third and foiu^th leg are more numerous. 

 We find a median row of three equidistant spines on the under- 

 side of the til)iip accompanied by several lateral spines, and three 

 pairs of spines on the underside of the metatarsi apparently 

 accompanied by a pair of lateral spines. There are also two cir- 

 cular sockets for spines on the third patella, but the spines them- 

 selves are missing as spines are often broken off in life and still 

 more commonly after death. Legs in order 4123.
