The PALPI of the male are most characteristic. Each 

 femur, near its base, exhibits several extremely long teeth. 

 Each of these bears a hair which usually arises from some 

 point a Httle removed from the apex of the tooth. These 

 large teeth arise from the whole under-surface of the joint 

 and are arranged uniserially, there not being room for 

 another series of teeth, although very small granulations 

 may be found on the lateral borders of the joint. The 

 large teeth are only three or four in number, the series of 

 hair-bearing processes being continued nearly to the distal 

 end of the joint as a number of tiny granulations, each 

 carrying its hair. This arrangement is found in no other 

 British Erigone. The femur is 1.21 mm. in length. 



The pateUa is -51 mm. long. It bears a most character- 

 istic apophysis at its distal end. This is curved, and thus 

 difficult to measure. Seen from the outer side it measures 

 .43 mm. from the dorsal surface of the distal end of the 

 pateHa to the point where the inward curve occurs, the total 

 length, including the curve, being nearly or quite equal to 

 that of the article itself. In shape the apophysis is tapering, 

 curved, and pointed at the extremity. It is directed down- 

 wards, slightly forwards, and finally near its termination 

 it is bent sharply inwards. 



The tibia, from its articulation with the pateHa to the 

 tip of the external process, measures .45 mm. Its height 

 at the apex between the tip of the superior process and 

 that of the inferior one is .31 mm. It presents a slender 

 curved stem with a distal expansion bearing four processes 

 or apophyses. Of these the dorsul or superior one is bluntly 

 pointed. The inferior one is slightly gibbous on its lower 

 surface, but bears no actual tooth in the examples examined. 

 The internal process is squarely truncated, whilst the 

 external one is narrow, pointed and curved, being directed 

 forwards and upwards. The shape of these apophyses is 

 quite unlike that of any of our British species, and differs 

 distinctly from all the figures of the other species shown in 

 Kulczynski's monograph.^ 



The tarsus measures .49 mm., it bears a paracymbium 

 similar to that found in other species, and is in no way 

 characteristic.
