between the ej'es in this genus, but Dr. J. C. C. Loman ^ 

 lias already commented upon two female specimens of 

 Ihalonius which did not possess this thorn. 



Podoctis taprohanicus, sp. n. (PI. I. fig. 4.) 



Dorsal surface strongly convex. Scutum about as long as 

 the metatarsus of the third leg, slightly longer than the 

 patella + the tibia of the third leg, and a little shorter than 

 the patella + the tibia of the fourth. Transverse grooves 

 five in number, the first two meeting one another in the 

 mesial line. A pair of long and shar^ily ])oiiited thorns, 

 which are stout at the base, are situated near the middle 

 of the fourth abdominal area. On each side of the anterior 

 margin of the scutum a ridge supporting a row of six conical 

 granules is present, and this ridge is joined to the ocular 

 tubercle by a distinct arch, formed by two fused graimles. 

 A tooth-like projection is placed on each side of the scutum, 

 close to the lateral margin and some distance behind the 

 anterior margin. Numerous very fine granules, each carry- 

 ing a short hair, also occur on the surface. Towards the 

 middle of the hinder part of the cephalothoracic area there is 

 a pair of slight elevations on which granules similar to those 

 on the rest of the surface are present, one or two of them 

 being slightly enlarged, however ; one or two slightly en- 

 larged granules are also present laterally in this part of the 

 scutum. Besides the minute granules, each of the •abdominal 

 areas of the scutum, except the fourth, has a few larger 

 granules, which are arranged in a single transverse row. 

 Ocular tubercle placed slightly nearer the anteiior margin of 

 the cephalothoracic area than to the posterior margin. It is 

 very wide at the base ; in the middle there is the usual thorn ; 

 it has a very stout and wide base, which is rounded poste- 

 riorly, but almost vertical in front; tiie thorn which springs 

 from this tubercular base is straight and fairly long, and as 

 is usual in the genus Pot/oc^iV, it is directed forwardly. Each 

 of the two eyes is situated on the side of a small lateral 

 tumulus on the ocular tubercle. Except anteriorly, where it 

 is quite smooth, its surface is furnished with numerous 

 minute granules. Several slightly larger granules can be 

 distinguished, one of them being placed in the middle of the 

 upper surface of the basal portion of the spine and one or two 

 others on each side of it ; on each side of the spine itself a 

 slightly enlarged granule is also present. Free dorsal seg- 

 ments 1-3 each furnished with a transverse row of enlarged
