Palps (fig. 5c). — The i)alps are almost smooth and provided with fairly 

 long pointed hairs; the hand bears above the four doisal tactile hairs, placed in 

 a square; in addition to these four lactile hairs the hand has posteriorly a vertical 

 row of three or four at the base of the hand; both fingers bear several but not 

 so many as in /. Siamensis n. sp. The trochanter, which is about twice tlie length 

 of the breadth is provided with a rather distinct stalk ; the anterior moderately 

 convex, while the })osterior beyond the sudden moderate concavity, has a rather 

 sudden convexity. The femur, which is almost four times longer than broad, has 

 a fairly distinct stalk; the anterior outline has first a shorl concavity and beyond 

 that a moderate convexity to near the tip; the posterior has beyond a low eleva- 

 tion, which markes the stalk off, a very low concavity, which is followed by a 

 more marked distal convexity. The tibia, which is slightly shorter and broader 

 than the femur, and three times longer than broad, has a distinct long stalk; the 

 anterior surface is beyond the almost straight margin of the stalk and a low well 

 marked elevation, moderately convex; the posterior outline is slightly convex from 

 base to tip. The hand is scarcely so long as the tibia and 16 broader, and much 

 shorter than the finger; it is scarcely twice as long as broad; the anterior margin 

 is beyond the stalk very strongly convex, while the posterior is only slightly so. 

 The fingers have their tips bent suddenly to establish pointed strong hooks. 



Coxae. — The coxae are placed on a level with the maxillae and on level 

 with each other; the first pair are as broad as they are long and not widened out 

 towards the extremity; the second pair are longer, moderately widened out towards 

 tlie extremity and more narrower than first; the third pair are widened out distally 

 in so high a degree, that it appears triangular, and is as long as, but much nar- 

 rower than the preceding pair; the fourth pair are the longest and have their 

 interior margin as long as that of the first pair, because they are triangularly 

 pointed and have the point directed obliciuely forwards towards the middle; the 

 inner and hinder margins merge into eacli other, as the postero-exterior corner is 

 smoothly rounded. 



Legs. — The legs are, compared with the size of the body exceptionally 

 weak and thin. The hairs are moderately long and slender; dorsally at the base 

 of the first tarsal joint of the two last pair of legs we find a "tac/i/e" hair, in 

 length sliglitly surpassing the second tarsal joint; the lateral terminal hair of the 

 tarsi is long, slender curved with three distal brandies. The aroliiim extends 

 beyond the claws and is distinctly widened out towards the lip, and the sucking 

 cup has the margin finely serrated. The basal femoral part is widened out distally, 

 much broader than the more distal joints and almost as long as the tarsi ; the 

 tibial femoral part is scarcely half as long as the basal part, moderately enlarged 

 outwards and distinctly shorter than the tibia; this is about 13 times longer than 

 the second tarsal joint, which is again 14 limes longer than the first. The femur 

 of the fourth pair of legs is three times longer than deep, not very much raised
