pointed ; the scutum is furnished with six plumose haii's, a 

 transverse row of four hairs being situated on the anterior

 on the same platelet as the eye, the latter being placed 

 in front of the hair. There are also four longitudinal rows 

 of slender plumose hairs, the outer rows each consisting of 

 two long hairs and a shorter posterior hair, the inner rows 

 each of three long hairs. On each side of the genital 

 opening there are two hairs of moderate length and also an 

 inner border of three short hairs. All these hairs on the 

 dorsal surface are slender and plumose, and their sockets 

 are not enlarged. Hairs on venter few in number; there is 

 a pair of short fine hairs between the last coxa?, followed 

 posteriorly by three pairs of plumose haii's. Integument 

 marked with a sculpturing of very fine wavy lines as in 

 P. podapolipopliagus. Projecting portion of peritreme short.

 the basal part being short, compact, well defined, and 

 strongly convex dorsally; the re»t of the chelicera forming 

 a long slender style, which, apparently, is not bifid at the 

 end as in the two known species of P'lmeliaphilus^ but ends 

 in a single minute tooth or claw, which is slightly curved. 

 Palp short : the basal segment is salient laterally and has 

 a sharp prominent transverse ridge on its dorsal surface; 

 second segment dorsally with a long slender plumose hair; 

 the next two segments each with a shorter hair, which is 

 very fine and apparently not plumose. Legs long and 

 slender, and furnished with numerous fine plumose hairs. 

 With the exception of the last, eacii of the coxse has a pair 

 of short hairs, the inner hair being fine and not plumose, 

 the outer stouter and apparently plumose. There is al^o a 

 forwardly directed plumose hair on the anterior surface of
