1 14 THELYPHONID^E. 



Sculpturing of upper side practically as in H. oatesii. Sterna 

 also as in that species, but with the punctures a little more 

 numerous. Chela; with the spines on the lower side of the 

 trochanter and femur much smaller : upper side of trochanter 

 smooth, at most obsoletely spined.its anterior border straight ; femur 

 about as long above as anterior edge of trochanter, rather coarsely 

 granular and punctured below, a few spines also on its upper 

 inner edge, otherwise smooth, sparingly punctured ; tibia with a 

 few granules below and internally, smooth and punctured else- 

 where ; apophysis long and slender, almost as long as upper side 

 of tibia, and reaching almost to tip of fingers, its posterior edge

A. Hypoctonus tvoodmasoni, extremity of chela of <$. B. H. saxatilis, ditto. 

 C. H. andersoni, tibial apophysis. D. H. ranguncnsis, first abdominal 

 sternum of 5 E. H. formosus, ditto. F. H. binghami, ditto. 



straight and unarmed, its apex truncate and bidentate, the 

 anterior border lightly concave in its basal and distal portions, 

 lightly convex submesially, and armed with four denticles ; hand 

 wide, as wide as long, strongly convex and smooth above ; a deep 

 semicircular excision on its inner edge and on the base of the 

 linger, the area behind the excision produced into a weakly 

 denticulate rectangular prominence ? immovable finger much 

 narrower at base than in the middle. Ontmatoids small, more than 

 their diameter apart. 



$ . Very like the female of If. binghami, but with the ommatoids 

 small, more than a diameter apart ; the lower side of the femur of 

 the chela more numerously granular and punctured as well, the 

 tipper side of the trochanter without granules ; the 1st abdominal 

 sternum not widely rounded behind, but with its posterior border 

 strongly produced into a large subquadrate lobe ; the anterior 

 half of the plate marked with a pair of subcircular pits, separated 

 from each other by a space which distinctly excels their diameter. 



Length up to about 27 mm. 



Loc. Tenasserim, near Mount Moolevit.
