Japan and the Loo-Choo Islands. 633 



■distinct dark ring near the apex, but often more extensively 

 •darkened ; tlie apex of the metatarsi and the tarsal segments 

 are usually slightly darkened also. 



Material. — A male and female, collected by Mr. S. Aki- 

 yama at Idzu, Japan, 



Pseudohiantes insulanusj sp. n, 



(J. Scutum unarmed; a few indistinct and obsolete 

 granules only are present on tlie posterior segments of the 

 scutum and a number of obsolete granules along the lateral 

 margins. Ventral surface: cox^e of first leg witli a number 

 of granules as in P. japonicus, sp. n. 



Chelicfirce. — Second segment considerably swollen ; near 

 the inner side of its dorsal surface it is furnished with three 

 granules arranged in a longitudinal series, two of them being 

 •minute, but the apical one large and couicah A row of four 

 teeth is present on the edge of the immovable finger ; the 

 first two teeth (counting from the proximal end) are rather 

 large, the two remaining ones minute. Close to its proximal 

 end the edge of the movable finger is armed with a fairly 

 large tooth, which is separated by a considerable gap from 

 the four teeth of the distal half- the latter resemble those. of 

 the immovable finger, the first two of them being fairly large 

 and the other two small. 



Palp. — Trochanter armed above with a conical process 

 And with two others below. A row of granules is present on 

 the upper surface of the femur and a row of six well-marked 

 processes on its ventral surface ; a dentiform granule is 

 situated on the inner side below. Tibia and tarsus strongly 

 armed ; the number and relative size of the spines being 

 exactly the same as in P.japonicus, 



Legs. — Number of tarsal segments 9, 20, 7, 8, 



Measurements in mm, — Tolal length 3*75; length of first 

 leg (from base of femur) 11*75, of second 19, of third 15, of 

 fourth 19-75. 



\_Colour. — Owing to the length of time that this specimen 

 Las been preserved in spirit the markings have practically 

 disappeared, and so I have not described tlie coloration.] 



$ . In the same tube as the male example described above 

 there is another specimen which I identify with doubt as the 

 female of the same species. It is much darker in colour than 

 the male specimen, and differs also in the following details of 

 structure : — 



Chelicera, — Second segment not swollen, and none of the 

 four granules of the row on its dorsal surface are of large
