and tlie favsus strongly bont downwards, so tliat Its spines 

 work anrainst the tibia. 



The structure of the palp in this new genus is very similar 

 to that of the Opiliones of the family Hiuzuanidic (=Bi- 

 antida;). In P. japonicus, sp. n., the feninr ofc" the palp is 

 quite unarmed except for a conical granule placed near the 

 base below, and thus resembles completely that of the Hinzu- 

 anidie. In P. (/eniculutus, Poc, and I*. insulanuSy sp. n., 

 there may be only a row of granules on the ventral surface 

 of the ))alp or a row of quite well-developed processes may 

 be present ; these processes do not bear spines, but only fine 

 liairs.

Scutfim. — A pair of sharply pointed processes, which are 

 well marked although not very long, are presejit in the 

 middle of the second of the four divisions into which tho 

 abdominal part of the scutum is divided ; and a pair of 

 minute obsolete granules, placed further apart from one 

 another than the processes of the second division, occur on 

 the third. Obsolete granules may also be present on the last 

 segment of the scutum and on the lateral margins; except 

 for the pair of processes and the inconspicuous granules 

 mentioned, the surface is quite smooth. Ventral surface'. 

 coxa of tirst leg furnished with a number of granules. 



Chelicera. — iSecond seo-ment with a number of oraimles on 

 its dorsal surface, tiie one which is placed nearest to the apex 

 being the largest. 



cJ . Chelicera of the male a little more swollen than that 

 of the female, especially its second segment. A small tootii 

 is situated at the proximal end of the immovable finger, and 

 it is tollowed by a large tooth, and then comes a row of four 

 teeth, the proximal one of them being fairly large, the others 

 minute. A fair-sized tooth is present near the proximal end 

 of the movable tinger, and it is separated from the row of 

 teeth at the distal end by a slight gap ; the latter are four in 

 number, two being large and two small. 



? . In the female sex the edge of the immovable finger of 

 the chelicera is armed with minute teeth only. Movable 

 finger with a row of three teeth near the distal end, the 

 proximal one being the largest. 



Pulp. — A sharp conical granule, which bears a hair, is 

 present on the dorsal surface of the trochanter and another
