140 PHILORTHRAGORISCUS SERRATUS. 



the brown-coloiired distal part of the claw for a distinct 

 joint. In the middle of the concave side the falcate claw 

 bears a setose spine upon a conical tubercle; near the 

 base of the same joint a similar smaller seta is placed more 

 dorsally. 



The palps (fig. 3) differ greatly in feature from those 

 in DinemaUira en Echthrogaleus ; they possess a long basal 

 joint, that is faintly S-like bent, and occupies about 

 three fourth of its total length. This joint is nearly equally 

 broad throughout its whole length, but it appears not to 

 be quite cylindrical , for on its inner as well as on its 

 lateral side a longitudinal depression is visible; on the 

 middle of the dorsal side it bears two long and a short 

 seta , situated next to each other. The distal part of the 

 palp consists of three or four not distinctly separated joints 

 and ends in a rather sharp terminal apex. 



The anterior foot-jaws (fig. 4) possess two joints, nearly 

 equal in length, but the distal of them about half as slender 

 as the proximal one. The distal joint bears at its extre- 

 mity two slightly curved, digitiform appendages, of about 

 the same length , but the superior stouter than the inferior 

 one ; both are provided at their dorsal side with irregularly 

 placed spines, whereas their ventral face is limited on each 

 side by a regular row of them , arranged like a comb. In 

 the axil between the two digitiform appendages a shorter 

 conical process arises, beset with small spines over its 

 whole surface, except a terminal cylindrical part. These 

 foot-jaws differ greatly in shape from those of Dinematura, 

 which bear at their extremity only a single curved finger- 

 like appendage and springing near its base, nearly under 

 a right angle, another process, that is more faintly curved 

 and beset with small spines ; in the axil between both pro- 

 cesses there is a small tubercle , bearing a tuft of short 

 setae on the top. 



The posterior foot-jaws (fig. 5), also two-jointed but much 

 larger , have a high compressed basal joint and a much 

 more slender claw-shaped terminal one, that, bent backward,
