new Tropical and Southern Opiliones. 41:9 



tubercles, the last two segments of the scute and the following 

 free terga have a median tubercle equalling the others in size. 



Mandibles of normal size ; basal segment with i distal 

 tooth, second segment with 3 proximal teeth. 



Palpi scarcely longer than dorsal scute ; trochanter armed 

 with 1 upper and 2 lower spiniform tubercles ; femur with 4 

 inferior (whereof 3 are proximal) and 1 inner distal ; patella 

 with 1 external, 2 internal ; tibia with 3 pairs, tarsus with 2 

 pairs of long spines; patella, tibia, and tarsus of palp sub- 

 equal in length. 



Femur of first leg with 5 spines below, the second and 

 third the longest, the fifth the shortest; the rest of the femora, 

 unspined, granular ; coxas granular, not spined, except the 

 posterior aspect of that of the second leg, which bears 1 spine. 



Abdominal sterna with a transverse row of small tubercles. 



Measurements in millimetres. — Total length about 4*5 

 (contracted) ; palp 3-5 ; first leg 7, second 12, fourth 15. 



Loc. Ceylon: probably Kandy [E. E. Green). 



On the evidence supplied by one specimen I do not feel 

 justified in separating this form generically from the Pinang 

 species described by Thorell as Podactis armaiissimus (Ann. 

 Mus. Genova, (2) x. pp. 99-103, 1890). Specifically the 

 two certainly differ in colour. A further difference is furnished 

 by the larger size of the dorsal tubercles, justifying their 

 description as " dentes fortes ^' in P. arrnatissimus. Nor is 

 the ocular spine in P. piciulus describable as " dentem sat 

 fortem obtusissimum " ; nor has the femur of the first leg 

 spines on its dorsal margin.
