74 Mr. S. Hirst on neio Ilarvest-meyi 



iiiiiuite grannie is situated on the middle of this arch. 

 Numerous minute granules, bearing short hairs, are present 

 on the surface and on the bases of the large thorns. A 

 transverse series of larger granules is present just in front of 

 the first distinct transverse groove, and a similar row is 

 2)reseut on each of the following areas of the scutum, with 

 the exception of the penultimate one. Ocular tubercle situated 

 at quite a short distance from the anterior margin ; it is 

 wider than that of P. tajirohanicus, its width being about 

 half the length of the scutum, and is low laterally; in the 

 middle there is the usual long thorn, the base of which is 

 very wide, but not nearly so stout as the base of the central 

 thorn of the ocular tubercle of P. taj^rubanicus. Each of tlie 

 free dorsal segments has a transverse row of granules similar 

 to those which are present on the abdominal segments of the 

 scutum. 



Ventral surface furnished with numerous minute granules; 

 a number of larger conical granules occur on the coxa of the 

 first leg, and other granules which are not so large or distinct 

 are present on the coxa of the second. 



Chelicera. — Proximal segment of ciielicera rather long, but 

 not slender ; its length is about equal to that of the second 

 segment (not including the finger) ; on the inner side it has 

 three rather long tooth-h'ke processes and also one or two 

 granules ; on its outer side there is a series of six long pro- 

 cesses (including the apical one, which is not so strong or so 

 well defined as the others). Second segment considerably 

 stouter than the first ; a little process is present below on its 

 inner side near the proximal end ; dorsally this segment is 

 furnished with a number of minute denticles and also with 

 four larger tooth-like tubercles, of which the largest one is 

 placed near the point of attachment of tlie movable finger 

 and is sometimes divided into two points at its apex. Both 

 the fingers have four teeth on their edge, three of which are 

 placed near the apical end of each finger, and the remaining 

 tooth, which is very large in the case of the movable finger, 

 is placed midway between these three distal teeth and the 

 proximal end of tlie finger. 



Note. — This descri])tion is based on the chelicera of a 

 S[)ecimen which I believe to be a fully adult male. The 

 clieliceree of the other specimens are very different in appear- 

 ance, the proximal segment being considerably shorter and 

 armed with fewer lateral processes. I think that these 

 differences are not due to sex in this particular instance, but 

 merely to immaturity. The dentition of the fingers is the 

 same in these specimens as in the adult one.
